4 Fakta Ilmiah Mengejutkan Jika Baju Antariksa Astronot Rusia rusak

Unknown astronauts, astronomy, astrophysics, science

Profesi astronot kerap menjadi jawaban bila anak-anak diminta menyebutkan impiannya untuk masa depan. Untuk pikiran polos para kecil itu, astronot memang kelihatan seperti pekerjaan yang sungguh menarik. Astronot memiliki kesempatan melaju dan menjelajahi benda-benda langit yang jarang dapat dilihat atau dicapai oleh manusia biasa. Tetapi pada kenyataannya, ada banyak risiko yang harus dihadapi seorang astronot selama bertugas di ruang hampa.


 Berbicara tentang astronot tentu tidak lepas dari pakaian luar angkasa (
 spacesuit
 ) atau lebih dikenal sebagai pakaian astronot yang begitu terkenal. Pakaian astronot diciptakan secara khusus untuk membantu manusia tetap bertahan ketika berada di ruang angkasa dengan kondisi lingkaran yang sangat berbeda dari Bumi. Pakaian ini dilengkapi dengan teknologi maju sehingga bisa mensimulasikan suasana Bumi bagi siapa pun yang mengenakannya di luar atmosfer kita.


 Berikut ini empat fakta ilmiah mengenai apa yang bakal terjadi kepada seorang astronot apabila pakaian antariksa mereka rusak ketika sedang melakukan ekstravaksi dalam ruang angkasa:
 1. Kelebihan Tekanan: Astronot bisa kehilangan kesadaran hanya dalam hitungan detik akibat tekanan rendah.
 2. Pengembunan Cairan Tubuh: Air dan cairan tubuh lainnya dapat mendidih dengan cepat di lingkungan tanpa atmosfer seperti itu.
 3. Pembengkakan Ekstrem: Akibat hilangnya udara bertekanan, jaringan tubuh menjadi sangat membuncit.
 4. Kebocoran Udara Dalam Paru-paru: Jika paru-paru pecah karena perubahan tekanan, hal tersebut dapat menyebabkan kerusakan serius atau bahkan kematian.
 Informasi ini disimpulkan dari beberapa referensi tentang situasi darurat luar biasa semacam ini bagi para pekerja luar angkasa.

<h2>
 1. Badan astronot akan membesar
</h2>
<img data-document-id="cms/api/amp/image/AA1C8suE" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1C8suE.jpg"/>

 Salah satu aspek dari pakaian astronot adalah terdapatnya kontrol tekanan atmosfer. Menggunakan kostum astronot membuat para astronot dapat bertahan dalam kondisi dengan tekanan sama seperti di permukaan Bumi walaupun mereka berada di ruang luar yang memiliki tekanan sangat rendah. Ini krusial bagi keberlangsungan hidup astronot saat melakukan aktivitas di luar pesawat ruang angkasa.


 Keadaan horor bakal dirasakan oleh seorang astronot apabila pakaian luar angkasanya rusak, terutama pada bagian yang mengontrol tekanan. Dalam situasi tersebut, badan sang astronot bisa bertambah besar akibat gas-gas di dalam tubuh membesar dan hal itu dengan cepat dapat menjadi ancaman serius bagi kehidupan.


 Badan manusia mencakup sekitar 60% cairan dari keseluruhan bobotnya. Ini memberikan risiko besar bagi tubuh manusia untuk membengkak saat berada di ruang angkasa tanpa adanya pelindung seperti pakaian astronot. Menurut prinsip fisika, tingkat pendidihan secara langsung berkaitan dengan tekanan atmosfer.


 Oleh karena itu, jika seorang astronot berada di ruang hampa tanpa menggunakan pakaian antariksa, cairan di dalam tubuh akan dengan cepat mendidih dan menjadi gas serta uap air yang kemudian terakumulasikan di dalam sel-sel dan pembuluh darah. Secara fisik, tubuh astronot ini akan tampak membesar. Dalam konteks medis, situasi seperti ini dapat merusak fungsionalitas organ tubuh sehingga bisa mengarah ke kematian.

<h2>
 2. Astronot akan mengalami kekurangan oksigen.
</h2>
<img data-document-id="cms/api/amp/image/AA1C8IeR" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1C8IeR.jpg"/>

 Manusia memerlukan oksigen agar dapat bernafas. Di bumi, manusia tak mengalami kendala dalam pernafasan akibat kelimpahan oksigen. Sementara itu, kondisi tersebut bertolak belakang ketika berada di ruang angkasa dimana kadar oksigennya sangat rendah dan kurang mencukupi bagi keperluan nafas manusia.


 Baju astronaut dilengkapi dengan
 Portable Life Support System
 (PLSS) memiliki salah satu komponennya yaitu tabung oksigen. Tabung ini amat vital dalam memberikan oksigen kepada astronot selama melakukan aktivitas di luar pesawat ruang angkasa, memastikan bahwa mereka tetap bisa bernafas dengan normal. Oleh karena itu, jika terjadi masalah pada kostum astronot, lebih-lebih mengenai fungsinya sebagai sumber pasokan oksigen, sang astronot mungkin tidak mendapatkan cukup oksigen dan hal tersebut bisa menimbulkan kondisi hipoksia.


 Orang yang menderita hipoksia umumnya akan merasakan kepala berputar serta tubuh letih. Selanjutnya, mereka juga bisa menjadi bingung dan hilang arah. Bila situasi ini dibiarkan tanpa perawatan medis tepat waktu di stadium serius, hal itu bisa menimbulkan kerusakan otak tetap dan bahkan kematian.

<h2>
 3. Astronot akan mengalami kondisi panas berlebihan serta suhu tubuh yang terlalu rendah.
</h2>
<img data-document-id="cms/api/amp/image/AA1C8B3V" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1C8B3V.jpg"/>

 Suhu di ruang angkasa dapat menjadi ekstrem baik dalam keadaan dingin maupun panas. Saat sebuah area atau benda tertular cahaya matahari, temperatur bisa naik hingga sekitar 120 derajat Celsius. Di sisi lain, saat tidak mendapatkan paparan cahaya matahari, suhunya bisa jatuh drastis sampai -150 derajat Celsius.


 Pakaian astronot dirancang dengan sistem pelindung yang membantu mempertahankan suhu tubuh pemakainya secara konstan. Oleh karena itu, apabila pakaian ini rusak saat sedang di ruang angkasa, seorang astronot bisa menderita hipertermia akibat panas berlebihan serta hipotermia disebabkan oleh dingin ekstrem. Dalam kondisi terparah, orang tersebut bisa mengalami kejang, halusinasi, bahkan hilangnya kesadaran.

<h2>
 4. Mengalami paparan terhadap radiasi sinar kosmik
</h2>
<img data-document-id="cms/api/amp/image/AA1C8If5" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1C8If5.jpg"/>

 Bahan yang digunakan untuk membuat pakaian astronot adalah material anti-radiasi. Ini dilakukan agar astronot bisa terlindung dari ancaman paparan sinar kosmik. Saat mereka ada di ruang angkasa, pengaruh paparan radiasi tersebut jauh lebih signifikan. Di luar angkasa tak hanya kehilangan perlindungan lapisan atmosfer yang biasa menyerap sebagian sinar kosmik layaknya di Bumi, tetapi juga menghadapi tingkat radiasi sinar kosmik yang lebih tinggi akibat adanya sumber lain seperti supernova.
 black hole
 .


 Apabila seorang astronot berada di ruang angkasa ketika kostum antariksanya mengalami masalah atau cacat, risiko paparan terhadap radiasi kosmis bakal meningkat signifikan. Ini dikarenakan kurangnya perlindungan dari kostum tersebut serta absennya atmosfir Bumi untuk menetralkan radiasi itu sendiri. Paparan semacam ini bisa memicu kerusakan pada DNA atau penyakit kanker.


 Di penghujung hari, kita menyadari bahwa pakaian astronot tidak hanya semacam seragam pekerjaan layaknya kemeja polisi, militer, atau dokter. Justru, baju astronot adalah sebuah sistem kehidupan yang melindungi diri mereka saat berada di ruang hampa. Dapat disimpulkan jika keselamatan seorang astronot sangat tergantung pada pakaian spesial tersebut ketika bertugas di luar atmosfer bumi.

 In "Project Hail Mary," Ryan Gosling portrays a somewhat awkward and decidedly non-Ken-like character who transforms from a science instructor into an astronaut. This sci-fi thriller was showcased by Amazon MGM Studios during their presentation for cinema operators at CinemaCon on Wednesday.
 
 
 Gosling informs the government handler (Sandra Hüller), who has selected him for a perilous space mission, 'I added the 'not' to astronaut,' he says. 'I can’t even do the moonwalk,'
 
 
 The movie, based on Andy Weir's popular book of the same title, tells the story of an average person who discovers they have the skills necessary for venturing into the farthest parts of space.
 
 
 Phil Lord and Christopher Miller, known for directing hits like "The Lego Movie" and "21 Jump Street," have taken charge of a project based on a script penned by Drew Goddard. This script adapts Andy Weir’s novel "The Martian" into another successful film featuring Matt Damon.
 
 
 Rights to Weir's book ignited a bidding competition, ultimately leading to MGM Studios acquiring them for $3 million before their acquisition by Amazon. In 2023, Gosling took center stage in the blockbuster hit "Barbie." Additionally, he co-starred with Emily Blunt in "The Fall Guy" from last summer; although critically acclaimed, the film did not resonate with viewers.
 
 
 "Project Hail Mary" will debut in the United States on March 20, 2026.
 
 
 In contrast to other streaming platforms, Amazon MGM Studios has won over cinema owners by pledging to distribute more than a dozen films for theatrical release. The company’s appearance at CinemaCon aims to demonstrate the depth of this dedication.

A Giant Eye on the Sky: The ELT Could Detect Life at Proxima Centauri Overnight

Unknown astronomers, astronomy, astrophysics, extraterrestrial, science

<img data-document-id="cms/api/amp/image/AA1Bs4TY" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1Bs4TY.jpg"/>


 With the promise of revolutionizing our view of nearby star systems, the
 
 Extremely Large Telescope (ELT)
 
 is poised to do something no ground-based observatory has done before: detect potential signs of life on a planet orbiting the closest star to the Sun—
 
 Proxima Centauri
 
 —in under half a day. A new simulation study outlines how, thanks to its massive light-gathering power and unprecedented resolution, the ELT may be able to distinguish between living and lifeless planets based solely on the reflected light from their atmospheres.


 This breakthrough possibility is detailed in a 2025 study by
 
 Miles H. Currie
 
 and
 
 Victoria S. Meadows
 
 , which models the telescope’s ability to extract molecular fingerprints from exoplanets that don’t even transit their host stars. Their preprint,
 available on arXiv
 , suggests the answer to one of astronomy’s most enduring questions—
 
 are we alone?
 
 —might be just a few years away.

<h2>
 The next leap in Earth-based astronomy
</h2>

 Set high in the
 
 Chilean Atacama Desert, the ELT
 
 is scheduled to begin operations in 2028. With a primary mirror spanning 39 meters, it will be the largest optical/infrared telescope ever built on Earth. Its enormous surface area will allow it to collect more light than any previous ground-based telescope—and produce images up to 16 times sharper than Hubble.


 While other telescopes like
 
 JWST
 
 have made progress in analyzing exoplanet atmospheres during planetary transits, they face limitations. Most notably, many exoplanets—including some of the most promising Earth-like ones—
 
 do not transit
 
 from our line of sight. That’s where the ELT changes the game.


 Instead of waiting for a planet to pass in front of its star, the ELT will be able to capture
 
 reflected starlight
 
 directly from exoplanetary atmospheres. Using advanced high-contrast imaging and
 
 spectroscopy
 
 , it can isolate molecular signatures such as
 
 oxygen
 
 ,
 
 carbon dioxide
 
 , and
 
 water vapor
 
 —markers that could hint at biological activity.

<h2>
 Simulating the search for life
</h2>

 To evaluate the ELT’s potential, Currie and Meadows created detailed simulations of four Earth-like worlds orbiting nearby
 
 red dwarf stars
 
 :


 ・A lush, non-industrial Earth, rich in water and plant life


 ・An ancient Archean Earth, with primitive life and minimal oxygen


 ・A desiccated, oceanless world, more like Venus or Mars


 ・A barren, prebiotic Earth, with the chemistry for life but no organisms


 The researchers also modeled Neptune-sized
 exoplanets
 for contrast, expecting their thick atmospheres to yield different spectral patterns.


 Their goal: determine whether the ELT could reliably distinguish between living and lifeless planets, while avoiding false positives or false negatives. Could a planet without life appear to be thriving—or worse, could a truly habitable world be mistaken for a dead one?


 Their conclusion was clear: with only ten hours of observation, the ELT could likely identify atmospheric biosignatures on an Earth-like planet around Proxima Centauri. For gas giants, meaningful spectra could be obtained in just an hour.

<h2>
 Proxima Centauri: the prime target
</h2>

 Orbiting just 4.24 light-years away,
 
 Proxima Centauri
 
 is home to at least two known exoplanets—Proxima b and Proxima d. While the exact habitability of Proxima b is still debated, its location within the star’s habitable zone and relative proximity to Earth make it a prime candidate for future observations.


 If even a
 
 thin atmosphere
 
 exists around Proxima b, the ELT might be able to detect it. And if that atmosphere contains molecules associated with biology, the implications would be staggering.


 With the telescope’s capabilities, astronomers won’t need to rely solely on rare planetary alignments or indirect detection. They’ll be able to observe exoplanets directly, opening the door to a more continuous and detailed survey of nearby planetary systems.

<h2>
 Beyond detection: preventing misinterpretation
</h2>

 Importantly, the study also highlights the risk of spectral ambiguity. Not every detection of oxygen or methane should be taken as a smoking gun for life. Natural, abiotic processes can mimic the chemical output of organisms.


 That’s why the
 
 ELT’s resolution
 
 and sensitivity are so critical. By combining multiple spectral features and high-resolution data, researchers hope to develop stronger biosignature frameworks, reducing the likelihood of mistaken conclusions.


 In this context, the ELT will not just search for life—it will help define what counts as evidence.

Temuan Mengejutkan: Pabrik Planet 30 Juta Tahun yang Melawan Teori Ilmiah

Unknown astronomy, astrophysics, earth science, news, science

<img data-document-id="cms/api/amp/image/AA1BgUrf" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1BgUrf.jpg"/>

 
 
 - Para astronom selama ini percaya bahwa cakram gas dan debu yang membentuk planet di sekitar bintang muda hanya bertahan sekitar 10 juta tahun. Namun, sebuah penemuan terbaru dengan menggunakan Teleskop James Webb milik NASA menunjukkan bahwa untuk bintang dengan massa rendah, cakram ini bisa bertahan jauh lebih lama—hingga 30 juta tahun.


 Teleskop Webb mengungkapkan adanya lingkungan yang stabil dan kaya gas di sekitar bintang-bintang kecil, membuka kemungkinan baru bagi pembentukan planet yang lebih lama dari yang diperkirakan sebelumnya.


 Hal ini dapat berdampak besar pada pemahaman kita tentang evolusi planet dan kemungkinan adanya kehidupan di luar Bumi. Salah satu sistem yang menjadi perhatian khusus adalah TRAPPIST-1, di mana planet-planetnya mungkin memiliki waktu ekstra untuk terbentuk di zona layak huni.

<h3>
 'Planet Factory' di Tata Surya
</h3>

 Bila alam semesta punya buku foto, pasti terdapat banyak gambarnya adalah cakram gas dan debu yang berotasi; suatu area dimana planet-planet mulai terbentuk di sekitar bintang-bintang baru. Cakra ini memberikan material bagi pembentukan planet namun umumnya cuma tahan selama kira-kira sepuluh juta tahun sebelum pada akhirnya lenyap.


 Namun, para peneliti di Universitas Arizona mengungkapkan bahwa untuk bintang berukuran kecil dengan massa hanya seperseribu matahari atau kurang, diskus ini dapat bertahan lebih lama daripada yang diprediksi sebelumnya.


 Dalam studi yang dirilis dalam jurnal Astrophysical Letters, kelompok yang dikendalikan oleh Feng Long dari Laboratorium Planet dan Bulan, Universitas Arizona, mengungkapkan bahwa mereka telah menemukan sebuah cakram protoplanet dengan usia 30 juta tahun, tiga kali lipat dari estimasi sebelumnya.


 "Dengan cara pandang tertentu, cakram protoplanet mengungkapkan kepada kami versi bayi dari sistem planet, mencakup bagaimana Tata Surya kita kemungkinan terlihat ketika masih dalam tahap awal," jelas Long, yang juga merupakan Sagan Fellow di Laboratorium Planetologi dan Lunar.



<h3>
 Bagaimana Bintang Memengaruhi Umur Cakramnya
</h3>

 Umumnya, radiasi berenergi tinggi dari bintang muda dapat mendorong gas dan partikel debu keluar dari cakrawala, sehingga mengurangi sumber material yang dibutuhkan untuk menciptakan planet. Akan tetapi, para ilmuwan dalam tim ini mendeteksi sebuah bintang dengan nama formal WISE J044634.16–262756.1B, atau biasa dipanggil sebagai J0446B, yang ada di rasi Columba kira-kira 267 tahun Cahaya jauh dari Bumi. Mereka melihat bahwa disk formator planet tersebut mempertahankan keberadaannya selama tiga kali lipat lebih lama daripada estimasi awal mereka.


 "Walaupun sudah diketahui kalau kebanyakan cakram akan lenyap dalam rentang waktu 10 sampai 20 juta tahun, kami menemukan fakta bahwa untuk beberapa jenis bintang spesifik, cakram tersebut dapat bertahan selama yang lebih lama," ungkap Long.


 Sebagai penyedia material utama dalam proses pembentukan planet, umur dari cakram debu ini akan mempengaruhi seberapa banyak waktu yang dimiliki oleh suatu sistem untuk menghasilkan planet.



<h3>
 Mengapa Kestabilan Kimia Penting dalam Formasi Planet?
</h3>

 Walaupun bintang remaja menjaga diskus debu mereka dalam periode yang cukup panjang, kandungan kimianya tak banyak berevolusi. Peneliti mengungkapkan bahwa walaupun diskus tersebut bertahan hingga ratusan juta tahun, struktur kimianya tetap konstan. Hal ini menyiratkan bahwa kondisi kimia yang tenang bisa memberi kesempatan tambahan bagi pembentukan planet.


 Dengan mengamati komposisi gas pada cakrawala, tim ilmuwan menegaskan bahwa cakrawala yang ada di sekitar J0446B tidak berupa cakrawala debu (
 
 debris disk
 
 ), yang umumnya terbentuk dari bahan-bahan akibat benturan antara asteroid-asteroid tersebut.


 "Tim kami mengidentifikasi adanya gas semacam hidrogen dan neon, hal ini mengindikasikan keberadaan gas primordial pada cakram J0446B," jelas Chengyan Xie, seorang mahasiswi doctoral dari LPL yang turut serta dalam proyek riset tersebut.



<h3>
 Konsekuensi untuk Kehidupan di Luar Planet Earth
</h3>

 Kehadiran cincin gas yang bertahan cukup lama memberikan dampak signifikan pada peluang adanya kehidupan di luar Tata Surya. Satu sistem yang telah menjadi fokus bagi banyak peneliti adalah TRAPPIST-1, yang letaknya kurang lebih 40 tahun Cahaya jauh dari Bumi. Di dalam sistem tersebut ditemukan ada tujuh planet berskala sama seperti Bumi yang mengitari sebuah bintang katai merah; dan tiga di antara mereka berlokasi tepat di zona yang memungkinkan untuk mendukung kehidupan.


 Karena bintang beserta cakram planetnya dapat bertahan selama periode panjang dan termasuk ke dalam kelompok massa yang serupa dengan TRAPPIST-1, temuan ini menjadi sangat vital bagi pemahaman kita mengenai perkembangan sistem planet.


 Ilaria Pascucci, seorang professor bidang ilmu planet dari LPL dan juga penulis studi ini, menyatakan bahwa untuk mencapai tatanan orbit khusus layaknya yang terlihat pada sistem TRAPPIST-1, planets tersebut perlu berpindah posisi di dalam cakram, sebuah proses yang memerlukan adanya gas. Dia menjelaskan lebih lanjut bahwa kehadiran gas secara persisten dalam jenis cakram semacam itu bisa jadi merupakan penyebab utama di balik konfigurasi luar biasa TRAPPIST-1.



<h3>
 Apakah Yang Bisa Kami Petik Hikmahnya dari Disks Sejauh Ini?
</h3>

 Menariknya, cakram protoplanet yang berumur panjang ini tidak dijumpai pada bintang bert massa tinggi layaknya Matahari, sebab bintang jenis tersebut mengalami evolusi dengan kecepatan lebih cepat, memberikan durasi yang singkat bagi pembentukan planet.


 Walaupun Tata Surya kita memiliki rute evolusi tersendiri, penelitian terkait cakram protoplanet tipe ini tetap memberikan pemahaman penting mengenai proses pembentukan planet dalam kosmos. Penyelidik menyebutkan bahwa jumlah bintang dengan massa ringan jauh melebihi kuantitas bintang sekelas Matahari.


 "Melalui pemahaman akan evolusi dari bintang-bintang bermassa ringan serta mengetahui lebih banyak tentang cakram jangka panjang tersebut, kita dapat melengkapi kesenjangan pada koleksi gambar universal," ungkap Long.


 Temuan ini membuka peluang baru untuk mencari tanda-tanda kehidupan di luar Bumi dan menguji kembali pengetahuan kita tentang pembentukan planet, yang ternyata membutuhkan masa yang jauh lebih lama daripada estimasi kami sebelumnya.

NASA Data Indicates Our Universe May Be Nested Within a Black Hole

<img data-document-id="cms/api/amp/image/AA1BaXwR" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1BaXwR.jpg"/>

 A recent study utilizing information gathered by NASA’s James Webb Space Telescope about 263 galaxies has presented fresh support for an unexpected hypothesis.


 According to this theory, our universe might be contained within a black hole which emerged in an even more extensive cosmos.
 Digi24
 .


 Scientists at Kansas State University have found out that the majority of galaxies in our universe spin in the same direction.


 This questions the notion that our universe is uniform, suggesting that we should observe an equal distribution of galaxies spinning clockwise and counterclockwise.


 Lior Shamir, an associate professor of computer science, explained that there are two main possible reasons for this.


 One explanation is that the universe was born in rotation. This fits with the theory of black hole cosmology, which suggests that our universe exists inside a black hole in a larger universe.

 According to this theory, the Milky Way and all other galaxies would be inside a black hole formed in a much bigger universe.


 This idea goes against several widely accepted theories in cosmology, such as the Big Bang theory, which claims that the Big Bang marked the start of our universe.


 Though the new findings are intriguing, they don't definitively prove that the universe is inside a black hole.


 More evidence is needed to fully understand the implications of this model. Another possible explanation for galaxies rotating in the same direction is that the Milky Way's rotation might distort the data.


 If this is the case, scientists would need to adjust their methods for measuring distances in the universe.


 Adjusting these measurements could also explain other mysteries in cosmology, like why the expansion rates of the universe and large galaxies don't quite match up with expectations.


 The study was published in
 
 Monthly Notices of the Royal Astronomical Society
 
 .


 While the theory is still far from being proven, it opens up fascinating new possibilities for understanding our universe and its origins.

Webb Telescope Unveils Baffling Galaxy Images That Challenge Our Understanding

 The James Webb Space Telescope
 has spotted a giant galaxy that shouldn't exist.


 Using this exceptionally powerful telescope, a team of researchers were able to peer back in time and observe this
 never-before-seen spiral galaxy
 , dubbed the Big Wheel, as it looked just two billion years after the Big Bang.


 The farther out in space astronomers look using telescopes like the
 James Webb
 , the further back in time they're seeing, almost all the way to the Big Bang itself.


 A two-billion-year-old galaxy is considered young on a cosmic scale, but the Big Wheel's size at that point in history suggested that it should have been much older.


 The researchers determined that this galaxy stretched nearly 98,000 light years across, roughly the same size as our much-older home galaxy,
 the Milky Way
 , is today.


 Based on experts' current understanding of the early universe, it would be highly unlikely for a galaxy to achieve the Big Wheel's size in just two billion years.


 Study co-author Themiya Nanayakkara, an astronomer at Swinburne University of Technology in Australia, said: 'You have to remember that the Milky Way has had another 10 billion years or so to grow than the Big Wheel.'


 He and his colleagues concluded that the Big Wheel was the largest two-billion-year-old galaxy ever observed, and is likely much bigger than the Milky Way is today - roughly 10 billion years later.

<img data-document-id="cms/api/amp/image/AA1B9N4M" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1B9N4M.jpg"/>

 This presents a puzzling question: how did this galaxy manage to grow so enormous in such a relatively short amount of time?


 'Finding one of these galaxies is not a problem for cosmological theories, because one could be an outlier, but if we keep finding more, then I think we may have to say 'Okay, our models might need some refining,'' Nanayakkara told
 New Scientist
 .


 But he has a theory that could explain how the Big Wheel managed to grow so rapidly without breaking the laws of the universe as we understand them.


 It posits that multiple galaxies collided and merged in quick succession to form one large spiral galaxy, accelerating the growth rate that usually results from the gradual gathering of gas and dust in space.


 This may have been made possible by the Big Wheel's unusually dense surroundings.


 It is located in a region of space where galaxies are packed tightly together, 10 times denser than typical areas of the universe, Nanayakkara wrote in an article for
 The Conversation
 .


 'This dense environment likely provided ideal conditions for the galaxy to grow quickly. It probably experienced mergers that were gentle enough to let the galaxy maintain its spiral disk shape,' he explained.

<img data-document-id="cms/api/amp/image/AA1B6zrt" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1B6zrt.jpg"/>
<img data-document-id="cms/api/amp/image/AA1B9BkK" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1B9BkK.jpg"/>

 At the same time, 'the gas flowing into the galaxy must have aligned well with its rotation, allowing the disk to grow quickly without being disrupted. So, a perfect combination,' Nanayakkara added.


 He and his colleagues published their findings in the journal
 Nature Astronomy
 .


 Finding a galaxy like the Big Wheel was like finding a needle in a haystack. According to Nanayakkara, his team had lest than a two percent chance of discovering it.


 Now, the researchers will begin the hunt for more unusually large galaxies in an attempt to determine exactly how rare they are.


 If they aren't as uncommon as experts currently believe them to be, they may have to reevaluate everything they know about galaxy formation.

Could We Be Inside a Supermassive Black Hole? James Webb's Discoveries Spark New Cosmic Theories

Unknown astronomy, astrophysics, black holes, cosmology, james webb space telescope

<div class="section1">
 <div class="Normal">
 
 Scientists have long been intrigued by the secrets of the universe, and the James Webb Space Telescope (JWST) has provided unprecedented information since it started observing deep space in mid-2022. A recent JWST discovery posed some interesting and surprising questions: Is it possible that our entire universe is contained within a black hole? The bold hypothesis can potentially explain a mysterious cosmic phenomenon seen in the rotation of far-off galaxies.
 
 
 <h2>
 James Webb Space Telescope uncovers surprising galaxy rotation pattern
 </h2>
 
 
 The JWST's observations of the distant galaxies disclosed an intriguing and mysterious pattern. Approximately two-thirds of the galaxies rotate clockwise, and the remaining third rotate counterclockwise. Scientists had predicted a more or less equal proportion, presuming that the rotational direction would be random. The uniformity hints at the presence of some force or structure underneath that might be affecting the galaxies' rotation on a cosmic scale.
 
 
 <img data-document-id="cms/api/amp/image/AA1B81pD" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1B81pD.jpg"/>
 
 
 This finding is based on observations by the James Webb Space Telescope Advanced Deep Extragalactic Survey (JADES). Kansas State University lead investigator Lior Shamir mentioned two potential explanations for this unexpected trend: either the universe itself was created with a rotational motion, or existing cosmological theory must be rethought or reconsidered.
 
 
 <h2>
 The discoveries from the James Webb Space Telescope have ignited a novel theory about black holes in the cosmos.
 </h2>
 
 
 A proposal put forward long ago is what’s called black hole cosmology. According to this idea, our entire universe could potentially reside within a black hole, itself being an element of an even grander cosmic structure. Under this scenario, the event horizon—that critical boundary beyond which nothing escapes, not even light—would effectively mark the outer limit of our universe.
 
 
 Nikodem Popławski, a theoretical physicist and an ardent advocate of this idea, suggests that black holes could serve as origins for entirely new universes. According to his hypothesis, once matter gets drawn into a black hole, it behaves like a tightly wound spring which eventually snaps back, thus generating a fresh universe. He posits that this phenomenon might have triggered the Big Bang and led to the subsequent swift growth of our cosmos.
 
 
 Popławski elaborates on how a rotation within a black hole could influence the characteristics of the resulting universe. Should observations made by JWST provide indications of an apparent cosmic preferential spin, this would strongly support the black hole cosmology theory. In essence, if the cosmos consistently rotates, it would suggest that this rotational characteristic stems from the spin of the original black hole from which our universe emerged.
 
 
 <h2>
 The movement of the Milky Way and how it might affect the JWST's observations of distant galaxies.
 </h2>
 
 
 An alternate possible reason for the observed rotational patterns could relate to the movement of the Milky Way itself through space. Certain researchers suggest that the rotating nature of our galaxy might be altering the way JWST views distant galaxies receding from us. Should this be true, it may compel astrophysicists to reassess distance calculations across the cosmos and potentially resolve debates about the rate at which the universe expands.
 
 
 Although both these reports are intriguing, Lior Shamir emphasizes the necessity for further investigation to truly understand what’s happening. He stated, “It's crucial to determine whether the universe has an actual preferred orientation.” Such research is vital for broadening our comprehension of the laws governing the cosmos and might lead to groundbreaking insights into how the universe was formed and its fundamental structure.

Once in 80 years: Rare 'Blaze Star' nova set to brighten skies this week — how to spot it

Unknown astronomy, astrophysics, aurora borealis

One of these days, a rare astronomical event may brighten the nighttime sky. T Coronae Borealis (T CrB), more commonly referred to as the "Blaze Star," may go off at any moment. The normally unseen star will shine briefly during this once-in-a-lifetime event. Stargazers get a rare glimpse of this explosion in space.


 
 What Is Nova, the "Blaze Star"?
 


 Coronae Borealis is not a single star; rather, it is a binary star system. It is made up of a red giant and a white dwarf in orbit around one another. The white dwarf builds up enough hydrogen to explode once every 80 years. A nova, or abrupt rise in brightness, is the outcome of this.


 No eruptions have occurred since 1786, 1866, and 1946. One occurred in 1217 according to history, as well. The following eruption is scheduled between 2025 and 2026, say astronomers. Some estimates propose possible dates in 2027.


 
 What Makes This Event Unique?
 


 This nova is more than a fleeting moment of light. Because the system is 3,000 light-years from Earth, the explosion occurred thousands of years ago. The astronomers are getting a sneak peek into the past because the light is just now arriving on Earth.


 T CrB will be as brilliant as the North Star, Polaris, at outburst. It will remain visible to the naked eye for a few days. It might be hard to locate the constellation for those who are not used to it, but preparation can make the experience more pleasant.


 
 How and Where to View It
 


 The constellation Corona Borealis has T CrB within it. This small star arc is positioned in the northern hemisphere between Boötes and Hercules.

Galaxies Dwarf Our Imagination: Study Unveils the Truth

Unknown astronomers, astronomy, astrophysics, cosmology, galaxies

Galaxies turn out to be significantly larger than initially believed, stretching vast distances into deep space—distances so great that our home galaxy, the Milky Way, probably comes into contact with our nearest galactic neighbor, Andromeda.

 As you might believe, the journey to the drugstore seems quite lengthy," penned Douglas Adams in The Hitchhiker's Guide to the Galaxy, "however, compared to space travel, this distance is merely insignificant.


 The vastness of space is immense. Our home, Earth, resides as an insignificant speck circling a star located at the periphery of our Milky Way, which itself is merely one among approximately two trillion galaxies in the observable cosmos. Indeed, space spans an extraordinarily large expanse.


 The planet Earth is situated within one of the spiral arms of the galaxy.

 (referred to as the Orion Arm) which is located approximately two-thirds of the way out from the center

 We are aware of the size of the Earth — approximately 12,756 kilometers (7,926 miles) in diameter. Similarly, we know the dimensions of our Sun, which is roughly 1,391,000 kilometers (864,400 miles) across.


 However, just how vast is the Milky Way? Up until this point, the actual dimensions of galaxies have been an enigma.

<h3>
 The size of galaxies exceeds our expectations.
</h3>

 A recent research paper, featured in the journal
 
 Nature Astronomy
 
 It has been discovered that galaxies are much larger than initially believed, possibly even multiple times greater in size.


 The coiled shape of our galaxy constitutes merely its compact central region. In the case of the Milky Way, this spiral spans approximately 100,000 light-years.


 The starlight emanating from stars located within the spiral arms reaches approximately 7,800 light-years out into the vastness of space, marking what was once believed to be the boundary between the end of a galaxy and the start of deep space.


 The research has shown that extensive "halos" of gas stretch beyond the observable spiral arms of stars deeply into outer space.


 Astronomers were able to observe these gaseous halos for the first time thanks to advanced imaging technologies. These techniques allowed scientists to identify galactic gas halos extending more than 100,000 light years into space, significantly expanding our understanding of galaxy sizes.

<h3>
 Kissing galaxies
</h3>

 Actually, the halos of gas surrounding galaxies reach such vast distances into deep space that the galaxies themselves extend outwards considerably.

 .


 The research indicates that our Milky Way is probably colliding with our nearest neighboring galaxy, Andromeda — which is approximately 2.5 million light-years distant, as stated by Nikole Nielsen, the lead author of the study and a researcher at Swinburne University in Australia.


 "We’re now observing the limits of the galaxy’s influence, the point at which it transitions into becoming part of the environment surrounding it, and ultimately merging with the larger cosmic web along with other galaxies. These borders tend to be rather indistinct," explained Nielsen in a press release.


 Researchers believe this finding will aid in unraveling one of the most significant mysteries in astronomy: how galaxies develop over time?


 Examining the gaseous envelopes surrounding various kinds of galaxies — those

 , or those that no longer form stars—will aid in understanding how galaxies accumulate mass over time and the effects they have on one another during interactions.
