NASA's James Webb Space Telescope has observed the oldest supernova, GRB 250314A, dating back to when the universe was only 730 million years old, providing new insights into early star deaths and galaxy formation.
Astronomers using the James Webb Space Telescope have observed auroras and complex weather patterns on SIMP 0136, a starless, rogue brown dwarf, revealing detailed atmospheric structures, temperature inversions, and steady silicate clouds, driven by magnetic activity and internal heat, demonstrating that even isolated objects can have dynamic weather systems.
NASA's James Webb Space Telescope has directly observed a potential moon-forming disk around the exoplanet CT Cha b, revealing complex carbon-rich chemistry and providing new insights into planet and moon formation processes, with implications for understanding our solar system's origins.
NASA's James Webb Space Telescope has captured detailed images of the Sagittarius B2 molecular cloud, revealing massive stars, cosmic dust, and dense gas clouds in the Milky Way's most active star-forming region, providing new insights into star formation processes near the galactic center.
NASA's James Webb Space Telescope has detected methane gas on the dwarf planet Makemake, suggesting the presence of a thin atmosphere or geological activity, making it only the second trans-Neptunian object after Pluto with confirmed gas. Future observations are needed to determine the exact mechanism behind this volatile activity.
NASA's James Webb Space Telescope has observed the Earth-like exoplanet TRAPPIST-1 e, which may contain water and possibly have a secondary atmosphere, although its primary atmosphere has likely been stripped away by stellar activity. Further studies are needed to determine its atmospheric composition and water presence.
A team using the James Webb Space Telescope has detected methane gas on the dwarf planet Makemake, suggesting it may have a tenuous, active atmosphere or transient outgassing, making it only the second trans-Neptunian object after Pluto with confirmed gas presence.
NASA's James Webb Space Telescope is studying the Earth-sized exoplanet TRAPPIST-1 e, focusing on its atmosphere and potential habitability. Initial observations suggest the planet may have lost its primary atmosphere, but the presence of a secondary atmosphere with greenhouse gases like carbon dioxide remains possible, which could support liquid water. Further observations aim to clarify the planet's surface conditions and atmospheric composition, advancing our understanding of potentially habitable worlds beyond our solar system.
The Webb Telescope's initial observations of interstellar object 3I/ATLAS reveal a CO2-rich coma with minimal water and dust, suggesting a large, CO2-dominated nucleus around 46 km in diameter, challenging existing models of interstellar objects and their composition.
The James Webb Space Telescope has discovered a unique high-altitude haze on Pluto that acts as a thermostat, regulating its climate in a way not seen in other solar system bodies, with implications for understanding planetary atmospheres and early Earth conditions.
NASA's James Webb Space Telescope has found strong evidence of a potential gas giant planet orbiting Alpha Centauri A, the closest Sun-like star system to Earth. Although initial observations suggested the planet's presence, subsequent data did not confirm it, leading to the possibility that the planet may have moved or was a transient detection. If confirmed, this would be the closest exoplanet to Earth orbiting a Sun-like star and could significantly impact our understanding of planetary formation and evolution in binary star systems.
NASA's James Webb Space Telescope has found strong evidence of a potential gas giant planet orbiting Alpha Centauri A, the closest Sun-like star system to Earth. The discovery, based on infrared observations, suggests the planet could be a Saturn-sized gas giant in an elliptical orbit, but further observations are needed to confirm its existence. If confirmed, this would be the closest exoplanet to Earth and a significant milestone in exoplanet research.
A new Webb telescope image reveals a spectacular spiral nebula around two Wolf-Rayet stars in the Apep system, providing insights into star death and cosmic dust formation, and uncovering a third star influencing the nebula's shape.
NASA's James Webb Space Telescope celebrates its third anniversary by capturing detailed infrared images of the Cat's Paw Nebula, revealing new structures and star-forming regions, and continuing to advance our understanding of cosmic phenomena.
NASA's James Webb Space Telescope has analyzed 111 edge-on disk galaxies spanning up to 11 billion years, revealing that galaxies form a thick disk first, followed by a thin disk, with the timing depending on galaxy mass. This study enhances understanding of galaxy evolution and the formation of structures like the Milky Way, utilizing Webb's advanced capabilities to observe faint, distant galaxies and their components.
