Likely Saturn-Mass Planet Imaged by NASA Webb Is Lightest Ever Seen
Astronomers using NASA’s James Webb Space Telescope have captured compelling evidence of a planet with a mass similar to Saturn orbiting the young nearby star TWA 7. If confirmed, this would represent Webb’s first direct image discovery of a planet,…

Frigid Exoplanet in Strange Orbit Imaged by NASA’s Webb
A planetary system described as abnormal, chaotic, and strange by researchers has come into clearer view with NASA’s James Webb Space Telescope. Using Webb’s NIRCam (Near-Infrared Camera), researchers have successfully imaged one of two known planets surrounding the star 14…

Discovery Alert: A Possible Perpendicular Planet
The Discovery A newly discovered planetary system, informally known as 2M1510, is among the strangest ever found. An apparent planet traces out an orbit that carries it far over the poles of two brown dwarfs. This pair of mysterious objects…

NASA’s Webb Lifts Veil on Common but Mysterious Type of Exoplanet
Though they don’t orbit around our Sun, sub-Neptunes are the most common type of exoplanet, or planet outside our solar system, that have been observed in our galaxy. These small, gassy planets are shrouded in mystery…and often, a lot of…

NASA Webb’s Autopsy of Planet Swallowed by Star Yields Surprise
Observations from NASA’s James Webb Space Telescope have provided a surprising twist in the narrative surrounding what is believed to be the first star observed in the act of swallowing a planet. The new findings suggest that the star actually…

NASA’s Webb Images Young, Giant Exoplanets, Detects Carbon Dioxide
NASA’s James Webb Space Telescope has captured direct images of multiple gas giant planets within an iconic planetary system. HR 8799, a young system 130 light-years away, has long been a key target for planet formation studies. The observations indicate…

Discovery Alert: ‘Super-Earth’ Swings from Super-Heated to Super-Chill
The Discovery A possible “super-Earth” orbits a relatively close, Sun-like star, and could be a habitable world – but one of extreme temperature swings, from scorching heat to deep freeze. Key Facts The newly confirmed planet is the outermost of…

NASA’s Webb Exposes Complex Atmosphere of Starless Super-Jupiter
An international team of researchers has discovered that previously observed variations in brightness of a free-floating planetary-mass object known as SIMP 0136 must be the result of a complex combination of atmospheric factors, and cannot be explained by clouds alone.…
