<img data-document-id="cms/api/amp/video/BB1pTpN1" data-reference="video"/> <p> The James Webb Space Telescope Scientists have, for the first time, directly detected the crucial molecule of carbon dioxide in planets beyond our solar system. announced Monday. </p> <p> According to experts, the gas giants cannot support alien life forms; however, they provide insights into an enduring puzzle concerning the formation of far-off worlds. research published in The Astrophysical Journal . </p> <p> The HR 8799 star system, located about 130 light-years away from Earth, is merely 30 million years old — quite young when contrasted with our own solar system, which has existed for approximately 4.6 billion years. According to the research findings, a group of scientists based in the U.S., utilizing data from Webb, were able to directly observe carbon dioxide present in the atmospheres of all four recognized planets within this system. </p> <p> Webb's latest images of two well-known systems, HR 8799 and 51 Eridani and their planets have amazed scientists, providing further insights into the chemical composition of youthful gas giants,” as stated by NASA. statement . </p> <span> <img data-document-id="cms/api/amp/image/AA1B66uz" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1B66uz.jpg"/> </span> <p> They employed Webb’s coronagraph tools, designed to obstruct light from luminous stars so as to obtain a clearer image of the planets orbiting these stars. </p> <p> "Imagine holding your thumbnail up against the sun as you gaze into the sky," said lead study author William Balmer, an astrophysicist at Johns Hopkins University, to AFP. </p> <p> Typically, the Webb telescope identifies exoplanets by observing them as they pass in front of their parent star. </p> <p> The "transit technique" enabled Webb to indirectly discover CO2 in the atmosphere of the gas giant WASP-39 back in 2022. </p> <p> However, with this recent finding, "what we’re observing is the actual light emanating from the planet rather than just the signature of that light coming from the host star," explained Balmer. </p> <p> This isn’t simple—Balmer likened the task to trying to see fireflies with a flashlight next to a lighthouse. </p> <p> Although these gas giants might not support life themselves, it's conceivable that they could have had moons capable of hosting life, he noted. </p> <p> Several ongoing missions aim to discover whether life exists within the huge oceans hidden beneath the frozen crusts of multiple Jovian satellites. </p> <h2> "Key piece of proof" </h2> <p> Carbon dioxide (CO2) is crucial for life on our planet, which makes it an important element in the quest to find extraterrestrial life. </p> <p> Since CO2 turns into tiny ice particles in the extreme chill of space, detecting it can provide insights into how planets form. </p> <p> According to Balmer, Jupiter and Saturn likely initially formed through a "bottom-up" mechanism where numerous small ice fragments combined to create a solid nucleus. This core subsequently attracted gases to expand into massive planets. </p> <p> Thus, the recent finding serves as a "crucial piece of evidence" indicating that distant planets may also develop through processes akin to those observed in nearby planetary systems, according to Balmer. </p> <p> However, how widespread this phenomenon is across the universe remains uncertain. </p> <p> The aim of this type of research is to gain insight into our solar system, life, and our place within it by comparing them to other exoplanetary systems, thus helping us better understand our position in the universe, Balmer said We aim to capture images of other solar systems and observe their similarities or differences relative to our own. This will help us understand whether our solar system is exceptionally unusual or rather typical among others. </p> <span> <img data-document-id="cms/api/amp/image/AA1B62lY" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1B62lY.jpg"/> </span> <p> Astronomers have currently identified almost 6,000 exoplanets, most of which are quite large — and so far, none has been found to be inhabitable. </p> <p> According to Balmer, the "significant advancement we need to achieve" is concentrating our efforts on planets of similar size to Earth. </p> <p> The NASA Nancy Grace Roman space telescope plans to utilize a coronagraph for this purpose shortly following its anticipated launch in 2027. </p> <p> The previous year, the Webb telescope <span> discovered carbon dioxide </span> And hydrogen peroxide present on the surface of Charon, which is Pluto's biggest satellite. </p> <p> Balmer aims to utilize Webb for observing additional four-planet systems, yet he also noted that future funding has become uncertain. </p> <p> The previous week saw the Trump administration declare that NASA's top scientist had been let go, suggesting that further reductions loom for the American space agency. </p>

This new telescope lens could be a game-changer for space imagery

<p> Engineers and astronomers at the University of Utah have designed a unique new kind of telescope lens: a flat lens with microscopic etchings to refract light. If the concept can be scaled up, these lenses could one day replace the heavier, bulkier lenses and mirrors typically used in telescopes, particularly those of professional observatories on the ground and in . Down the line, they could also be implemented on amateur telescopes, the team says. </p> <p> "Our computational techniques suggested we could design multi-level diffractive flat lenses with large apertures that could focus light across the visible spectrum," Rajesh Menon, a Utah professor of engineering, said in a statement . </p> <p> There are two basic types of telescope: refractors and reflectors. A refractor uses lenses to refract light and bring it to a focus. Reflectors utilize at least two mirrors to reflect the light to a focal point. Because large lenses are heavy and expensive to make, larger telescopes tend to use mirrors (sometimes in combination with smaller lenses). Lenses can also suffer from a malaise known as chromatic aberration, in which different wavelengths of light are refracted to slightly different degrees so that different colors come to focus at different points, resulting in color fringing around objects. Optical technicians can alleviate this through the complex use of glass coatings and multiple lenses — though that adds cost and expense. </p> <img data-document-id="cms/api/amp/video/AA1Bbb7M" data-reference="video"/> <p> However, the days of bulky, expensive telescope lenses could soon be coming to an end thanks to the team's new flat lens measuring less than a millimeter thick. that has been developed by a team led by Apratim Majumder, who is a member of Menon's lab at Utah. </p> <p> "Our demonstration is a stepping stone towards creating very large aperture, lightweight flat lenses with the capability of capturing full-color images for use in air- and based telescopes,” Apratim Majumder, a member of Menon's lab at Utah and leader of the crew behind the new lens prototype, said in the statement. </p> <p> Majumder, Menon and their team designed a 100mm (4-inch) flat lens, where microscopic concentric rings are etched onto a glass substrate using a technique called "grayscale optical lithography," which is a variation of a method typically used for etching electronics onto a silicon wafer. Most of the half-millimeter thickness of the flat lens is the glass — the ringed grooves are just 2.4 microns deep. </p> <img data-document-id="cms/api/amp/image/AA1BkHks" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1BkHks.jpg"/> <p> The use of concentric rings on a flat lens isn't new — a precursor, called a Fresnel zone plate, tries to do the same trick but is unable to eradicate chromatic aberration. However, the Utah team's multilevel diffractive lens (MDL) is able to bring all the wavelengths of light for which it was designed to detect (400–800 nanometers, covering the range of visible light and into the near-infrared) to a focus at the same point, thanks to how the size of the rings and the spacing between affect how the incoming light is refracted. Because all the colors come to focus at the same point, there is no chromatic aberration. </p> <p> Back when the telescope was invented by Hans Lippershey in 1608, it was done so by experimenting with putting lenses together. Today, a telescope's optical design involves complex computer modelling and large amounts of data. </p> <img data-document-id="cms/api/amp/image/AA1Bky72" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1Bky72.jpg"/> <p> "Simulating the performance of these lenses over a very large bandwidth, from visible to near-infrared, involved solving complex computational problems involving very large datasets," said Majumder. "Once we optimized the design of the lens’ microstructures, the manufacturing process involved required very stringent process control and environmental stability." </p> <p> The resulting 100mm lens, which has a focal length of 200mm, was then tested on both the sun and the moon , successfully showing sunspots and (in an artificially color-enhanced image) accurate geological features on the lunar surface. The 100mm MDL weighs just 25 grams (0.88 oz), compared to the 211 grams (7.44 oz) of a similarly sized, commercially available 100mm lens that is 17mm thick at its curved center. </p> <p> The Hubble Telescope uses a 2.4-meter primary mirror with a total mass of 1,825 pounds (828 kilograms), and the James Webb Telescope incorporates 18 segments in its primary 21-foot (6.5-meter) mirror in total weighing (on Earth) 1,555 pounds (705 kilograms). On Earth , individual telescope mirrors have an upper size limit of 26-33 feet (8–10 meters), beyond which gravity starts to cause them to sag. The development of a flat, lightweight lens could therefore transform telescopes, particularly for launches where mass is a key limiting factor for getting off the Earth. </p> <p> A description of the flat MDL lens was published on Feb. 3 in the journal Applied Physics Letters . </p>

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

<p> <div class="section1"> <div class="Normal"> <p> 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. </p> <p> <h2> James Webb Space Telescope uncovers surprising galaxy rotation pattern </h2> </p> <p> 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. </p> <p> <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"/> </p> <p> 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. </p> <p> <h2> The discoveries from the James Webb Space Telescope have ignited a novel theory about black holes in the cosmos. </h2> </p> <p> 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. </p> <p> 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. </p> <p> 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. </p> <p> <h2> The movement of the Milky Way and how it might affect the JWST's observations of distant galaxies. </h2> </p> <p> 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. </p> <p> 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. </p> <p> <strong> Also Read | </strong> <strong> Is Sunita Williams going to receive additional compensation for her prolonged time in space?
