NASA’s Webb Observes Exoplanet Whose Composition Defies Explanation

Scientists using NASA’s James Webb Space Telescope have observed a rare type of exoplanet, or planet outside our solar system, whose atmospheric composition challenges our understanding of how it formed.  Officially named PSR J2322-2650b, this Jupiter-mass object appears to have an exotic helium-and-carbon-dominated atmosphere unlike any ever seen before. Soot clouds likely float through the […]

NASA’s Webb Detects Thick Atmosphere Around Broiling Lava World 

Researchers using NASA’s James Webb Space Telescope have detected the strongest evidence yet for an atmosphere on a rocky planet outside our solar system, as NASA leads the world in exploring the universe from the Moon to Mars and beyond. Observations of the ultra-hot super-Earth TOI-561 b suggest that the exoplanet is surrounded by a […]

Astronomers Map Stellar ‘Polka Dots’ Using NASA’s TESS, Kepler

Scientists have devised a new method for mapping the spottiness of distant stars by using observations from NASA missions of orbiting planets crossing their stars’ faces. The model builds on a technique researchers have used for decades to study star spots. By improving astronomers’ understanding of spotty stars, the new model — called StarryStarryProcess — […]
