James Webb Turns to Examine Planet Showing Potential Sign of Life
The James Webb Space Telescope has identified potential signs of life on exoplanet K2-18b through the detection of dimethyl sulfide gas, exclusive to lifeforms on Earth. [ more ]
'Overmassive' Black Holes Dominated Early Galaxies, Study Finds
Early supermassive black holes in ancient galaxies are smaller than those in our nearby universe but appear too big compared to the mass of stars in their host galaxies.
These early black holes were likely spawned by collapsing gas clouds and were more massive than their galaxies, but galaxies gained stellar mass over time. [ more ]
See the second farthest galaxy ever discovered in new NASA image
The James Webb Space Telescope (JWST) has discovered two new galaxies within the Pandora's Cluster, one of which is now the second-farthest galaxy seen by human eyes.
The newly discovered galaxy, Z-13, was estimated to have emitted light when the universe was about 330 million years old, and it traveled for about 13.4 billion light years to reach the JWST.
The discovery of these galaxies provides valuable insights into the early universe and the formation and growth of galaxies during that time. [ more ]
Daily Telescope: An ancient galaxy behind a veil of dust
Astronomers have observed a dusty galaxy that existed just 900 million years after the Big Bang.
The James Webb Space Telescope has allowed astronomers to see this type of galaxy that was previously invisible to the Hubble Space Telescope. [ more ]
Webb Telescope Uncovers Startling Phenomenon Growing Inside The Milky Way
The James Webb Space Telescope (JWST) captured new images of the heart of the Milky Way, revealing insights into the origin of the universe.
The images offer clues about how a cosmic environment impacts star formation and show previously unseen details of the galactic center.
JWST's Near-Infrared Camera (NIRCam) captured a dense and abundant star-forming region called Sagittarius C, including a pink pocket of massive protostars. [ more ]
Daily Telescope: A snapshot of 500,000 stars near the center of the galaxy
The James Webb Space Telescope has captured an image of a star-forming region named Sagittarius C, 300 light-years from the Milky Way's central black hole.
The image contains about 500,000 stars and will provide important insights into stellar formation.
The image shows a dense cluster with a massive protostar and smaller infrared-dark clouds where future stars are forming. [ more ]
It Rains Molten Sand on This Backward Alien Planet, Webb Telescope Data Reveals
WASP-107b is a gas giant planet that orbits its star backward, in what astronomers call a retrograde orbit.
Data from the James Webb Space Telescope (JWST) reveals that WASP-107b has a glowing tail of helium and rains molten sand.
Astronomers used JWST's Mid InfraRed Instrument to study WASP-107b's atmosphere and found that it contains water vapor, sulfur dioxide, and dense clouds of silicate. [ more ]
In a First, JWST Confirms an Atmosphere on a Rocky Exoplanet
Astronomers used the James Webb Space Telescope to detect the atmosphere of a rocky exoplanet, providing insights into early Earth's history and the search for life beyond the Solar System. [ more ]
The Webb Telescope Just Stumbled Upon A Lava Planet Twice the Size of Earth
55 Cancri e has a thick atmosphere rich in carbon monoxide or carbon dioxide, not vaporized rock. Previous studies suggest it might be carbon-rich with a diamond interior. [ more ]
The vastness of the universe can make it hard to comprehend, but capturing known objects on a cosmic scale helps bridge the gap for human understanding. [ more ]
Could JWST Solve One of Cosmology's Greatest Mysteries?
The James Webb Space Telescope's observations provide conflicting values for the rate of cosmic expansion, failing to settle the disagreement over the Hubble constant. [ more ]
The James Webb Space Telescope may have detected life beyond Earth, with strong evidence for a biosignature forthcoming.
While the detection of a biosignature is intriguing, it falls short of confirming life on other planets due to uncertainties and the complexity of defining life. [ more ]
JWST's Puzzling Early Galaxies Don't Break Cosmology--But They Do Bend Astrophysics
The James Webb Space Telescope (JWST) has observed bright galaxies that stretch back to the early universe, which is puzzling because galaxies shouldn't have had enough time to become so massive.
Studies suggest that the unexpected girth of these early galaxies could be attributed to astrophysical explanations like earlier-forming black holes or bursts of star formation, rather than a flaw in our understanding of cosmology. [ more ]
James Webb Spots Two Planets Solemnly Orbiting Dead Stars
Astronomers have spotted two gas giant exoplanets orbiting the remains of white dwarf stars, which is unusual due to the extreme forces involved.
The discovery suggests that gas giants could survive their hot stars collapsing and transforming into white dwarfs, but further confirmation is still needed. [ more ]
Rumors Circulating That James Webb Has Discovered Life on Other World
The James Webb Space Telescope has sparked speculation among scientists about the possibility of finding signs of alien life.
No definitive evidence has been found so far, but the telescope's observations could lead to the initial identification of potential biosignatures. [ more ]
No, the James Webb Space Telescope hasn't found life out there-at least not yet
Rumors suggest that the James Webb Space Telescope has found a planet with strong evidence of life.
NASA has clarified that while the telescope has not found definitive evidence of life, it may identify potential biosignatures that could indicate habitability. [ more ]
