Whoa! The JWST may have just dealt a blow to Dark Matter!! Recent observations by the James Webb Space Telescope (JWST) have reignited a debate over the nature of gravity and the role of dark matter in galaxy formation. The widely accepted Lambda-CDM model, which relies on dark matter to explain the formation of structures in the universe, predicts that early galaxies should be small and dim, slowly forming under gravitational pull. However, JWST has revealed ancient galaxies that are bright, large, and fully formed—contradicting these predictions. This unexpected data aligns with the Modified Newtonian Dynamics (MOND) theory, a radical alternative to traditional gravity models. Proposed in 1983, MOND suggests that early galaxy formation occurred rapidly without requiring dark matter. While this challenges long-standing cosmological frameworks, it also opens the door for fresh perspectives on how our universe evolved. #Astronomy #DarkMatter #JWST

Happy eclipse day "Humans are privy to all kinds of space wonders these days, thanks to Mars rovers, Jupiter orbiters, and giant space-dwelling telescopes. We can pull up Hubble’s famous deep field at any moment and see, on a single screen, several thousands of galaxies. But these captured marvels have been reassembled for the sake of our senses. Electromagnetic radiation is converted into visible light, strings of zeros and ones into meaningful information. The sights and sounds are filtered through the government agencies, space companies, and academic institutions that package them for public release. But to be in the path of totality during an eclipse is to experience the cosmos in a truly rare way. We can remove our eclipse glasses and stare at our star. We can experience unadulterated communion with the universe." https://lnkd.in/g9vmpdB2

James Webb Space Telescope Unveils Earliest Galaxies Ever Seen 🌌🔭 Researchers using the James Webb Space Telescope (JWST) have made a groundbreaking discovery by observing the formation of some of the universe's earliest galaxies. These findings, dating back to just 300 million years after the Big Bang, provide unprecedented insights into the early stages of galaxy formation and evolution. The Discovery 🚀 An international team of astronomers has announced the discovery of the two earliest and most distant galaxies ever seen. Located about 13.5 billion light-years away, these galaxies offer a glimpse into the universe's infancy. JWST's advanced infrared capabilities enabled these observations, allowing it to peer through cosmic dust and capture detailed images of distant celestial objects. Significance of the Findings 📊 Understanding Galaxy Formation: Provides insights into the processes that governed the early universe. Refining Models: Helps scientists refine models of galaxy formation and evolution. Historical Insights: Offers a clearer picture of the universe's history. Technical Details 🛰️ Instruments Used: JWST's Near Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI). Infrared Capabilities: Detects light traveling across vast cosmic distances, revealing previously invisible structures and phenomena. Future Implications 🔮 The success of these observations showcases JWST's potential to revolutionize our understanding of the cosmos. As it continues to explore the universe, JWST is expected to make more discoveries, enhancing our knowledge of star formation and galaxy evolution.

Gaia maps largest ever collection of quasars in space and time, Image: Astronomers have created the largest yet cosmic 3D map of quasars: bright and active centres of galaxies powered by supermassive black holes. This map shows the location of about 1.3 million quasars in space and time, with the furthest shining bright when the Universe was only 1.5 billion years old.The new map has been made with data from ESA’s Gaia space telescope. While Gaia’s main objective is to map the stars in our own galaxy, in

The VLT Survey Telescope (VST), the world’s largest visible-light telescope, has captured amazing images of distant galaxies, helping astronomers study the history of the universe. One image shows ESO 510-G13, a galaxy with a strange S-shaped disk that might have been caused by a long-ago collision. Another image features Hickson Compact Group 90, a group of galaxies that are swapping stars and gas, creating a bright halo around them. The telescope also photographed Abell 1689, a galaxy cluster more than 2.3 billion light-years away. This cluster's enormous mass bends light from objects behind it, an effect called gravitational lensing. These images give us valuable insights into how galaxies have evolved and interacted over time. #galaxy #universe #telescope #spacescience

Earlier this year, astronomers revealed one of the James Webb Space Telescope's most spectacular and intriguing discoveries yet. But it seems impossible to figure out exactly what they are.⁠ ⁠ The "Little Red Dots," as they're known, are hundreds of strange galaxies located in one of the most ancient regions of the observable universe. They're only about 2 percent the size of the Milky Way.⁠ ⁠ Here's where it gets really weird: Astronomers can't determine what they are because observing them from different mediums points to them being a different kind of object. And they were only visible for a period of roughly one billion years, and can't be located today.⁠ ⁠ Experts have two hypotheses, both of which could make heads spin. One is that the dots are the galactic version of packing the entire population of China into a single room. The other centers on a black hole so unfathomable that "supermassive" would be an insufficient description

James Webb confirms there's something seriously wrong with our understanding of the universe: In a striking discovery, James Webb and Hubble space telescopes have confirmed that the universe is expanding at varying rates depending on the observation point, which challenges our current understanding of the cosmos. This discrepancy is known as the Hubble Tension. It was first observed by the Hubble Space Telescope in 2019 and further confirmed by the James Webb Space Telescope in 2023, with recent combined efforts by both telescopes eliminating any doubts about measurement errors. The Hubble Tension arises from a conflict between two ways of measuring the universe's expansion rate. One method looks at the early universe, relying on the cosmic microwave background—the ancient afterglow of the Big Bang—to calculate the expected expansion. The other method focuses on the more recent universe, utilizing telescopes to observe stars and galaxies. The problem is, these two methods are yielding vastly different results. It's as if the universe has subtly changed its rules between its infancy and the present day. By observing over a thousand Cepheid stars in galaxies up to 130 million light-years away, the researchers have confirmed the reliability of Hubble's measurements across the cosmic distance ladder, thus ruling out measurement error as a cause for the Hubble Tension and suggesting a profound mystery at the core of our understanding of the universe's expansion. #universe #expansion #hubbletension #discovery #bigbang #hubblespacetelescope2019

🪐 Breaking Space Discovery! 🪐 Astronomers have found a mysterious 'Odd Radio Circle' near the center of our galaxy! Named Kýklos, this radio ring is unlike anything seen before—only visible at radio wavelengths and located just 6 degrees above the Milky Way’s plane. Previous ORCs were found high above the galactic plane or connected to distant galaxies, but Kýklos breaks all the rules! 🌌🌀 Could it be the remnants of a massive, unstable star shedding its outer layers? Or perhaps something entirely new? The next step: follow-up observations with the James Webb Space Telescope! Stay tuned as we uncover more about this cosmic mystery. 🛰️✨

What is black hole ?⚫️ It is a celestial object, a place in space, with such an immense gravity that nothing - not even light - can escape from it. The most common type of black holes are stellar black holes that form after collapse and explosion in supernova of big stars. The gravity of black hole is so strong because matter has been squeezed into a tiny space. Black holes can not be seen, but telescopes can detect the gas and matter orbiting them, in an area called accretion disk. The smallest are micro black holes (hypothetical). They formed when the universe began. The biggest, and recently classified, are ultramassive black holes UMBH. We all know the SMBH, supermassive black holes usually located in the center of the galaxies, but in recent years scientists have detected monsters like Ton 618 or Phoenix A, 66 and 100 billions of solar masses, they are extremely rare, active and voracious. Probably formed by the extreme merger of massive galaxies during the "Cosmic noon". By : Chathumal Lakshitha #sopa #sopaweeklypost #sopafacts
