  JWST Detects Thick Atmosphere on Ultra-Hot Rocky Exoplanet TOI-561 b

  Astronomers using the James Webb Space Telescope have discovered compelling evidence of a thick atmosphere surrounding TOI-561 b, an ultra-hot rocky exoplanet orbiting its star every 11 hours. Despite extreme radiation and molten surface conditions, the planet appears cooler than expected, suggesting heat-redistributing atmospheric winds and volati...

  JWST Detects Oldest Supernova Ever Seen, Linked to GRB 250314A

  Astronomers using the James Webb Space Telescope have detected the oldest supernova ever recorded, tied to gamma-ray burst GRB 250314A. Occurring when the universe was only 730 million years old, the explosion provides a rare glimpse into the first generations of stars and early galaxy growth, highlighting Webb’s unmatched ability to study the di...

  TRAPPIST-1e Methane Signal Likely False, Webb Data Suggests Airless Planet

  The TRAPPIST-1 planetary system, located about 39 light-years from Earth, hosts seven rocky worlds orbiting a cool red dwarf star. While several of these Earth-sized planets lie in the star’s habitable zone, new observations from the James Webb Space Telescope suggest their atmospheres may be too thin to support life. Earlier hints of methane aro...

  James Webb Space Telescope Spots an Exoplanet Losing Its Atmosphere in a Huge Helium Stream

  Astronomers using NASA’s James Webb Space Telescope have observed a massive helium cloud escaping from the super-puff exoplanet WASP-107b, marking the first direct detection of such atmospheric loss. Webb’s infrared data reveal an enormous exosphere nearly ten times the planet’s radius, with helium streaming both ahead of and behind the plane...

  James Webb Space Telescope Finds Unexpected Ultraviolet Radiation Around Young Protostars

  Astronomers using the James Webb Space Telescope have detected unexpected ultraviolet radiation around five young protostars in the Ophiuchus molecular cloud. Since infant stars are not expected to emit UV light, the finding challenges long-standing star-formation models. Researchers ruled out external illumination from nearby stars, concluding the...

  James Webb Telescope May Have Discovered Universe’s Earliest Supermassive Black Hole

  James Webb may have discovered the universe’s earliest supermassive black hole in galaxy GHZ2. Observations reveal high-energy emission lines, challenging existing models of rapid black hole and galaxy growth. Upcoming JWST and ALMA studies aim to confirm AGN activity and refine our understanding of early cosmic evolution.

  Webb’s Stunning View of Apep Shows a Rare Triple-Star System Wrapped in Spirals

  Webb’s mid-infrared images of Apep reveal a rare triple-star system producing vast carbon-rich dust spirals from colliding stellar winds. The two Wolf–Rayet stars and a distant supergiant create layered shells that record centuries of activity and enrich the galaxy with elements vital for future stars and planets.

  James Webb Space Telescope May Have Spotted the Universe’s First Stars, Astronomers Say

  Astronomers using the James Webb Space Telescope have detected a distant, metal-poor galaxy whose unusually massive, ultraviolet-bright stars match the expected signatures of Population III — the universe’s first stars. Through the help of gravitational lensing and Webb’s infrared sensitivity, researchers observed light from just 800 million ...

  James Webb Telescope May Have Spotted First Generation of Stars in the Universe

  Astronomers using JWST may have discovered Population III stars in cluster LAP1-B, offering new insights into early galaxy formation and the universe’s first luminous objects. JWST observations suggest Population III stars may have formed 13 billion years ago, helping trace early galaxies. These stars might be building blocks for larger galaxies ...

  Webb Finds Phosphorus-Bearing Gas in an Ancient Brown Dwarf

  NASA’s James Webb Space Telescope has detected phosphine (PH₃) in the atmosphere of the ancient brown dwarf Wolf 1130C, about 54 light-years away in Cygnus. This marks the first confirmed detection of a phosphorus-bearing gas in such a metal-poor object. The finding surprises astronomers, as phosphine was previously undetected in similar brown ...

  NASA’s JWST Produces First-Ever 3D Map of Distant Planet WASP-18b

  NASA’s James Webb Space Telescope has created the first-ever 3D atmospheric map of an exoplanet, revealing the extreme conditions on WASP-18b, an “ultra-hot Jupiter” located 400 light-years away. Using infrared eclipse mapping, scientists discovered a scorching hotspot over 2,700 °C where water molecules are breaking apart. This groundbreaki...
