For NASA’s TESS, Stellar Eclipses Shed Light on Possible New Worlds
A study of NASA’s TESS (Transiting Exoplanet Survey Satellite) data on stellar pairs undergoing mutual eclipses has uncovered more than two dozen candidate exoplanets, or worlds beyond our solar system. This method allows the mission to locate planets it couldn’t…

NASA Finds Young Stars Dim in X-rays Surprisingly Quickly
Scientists have found that young stellar cousins of our Sun are calming down and dimming more quickly in their X-ray output than previously thought, according to a new study using NASA’s Chandra X-ray Observatory. A paper describing the results published…

NASA’s Webb Redefines Dividing Line Between Planets, Stars
Planets, like those in our solar system, form in a bottom-up process where small bits of rock and ice clump together and grow larger over time. But the heftier the planet, the harder it is to explain its formation that…

NASA’s Hubble Sees Asteroids Colliding at Nearby Star for First Time
Like a game of cosmic bumper cars, scientists think the early days of our solar system were a time of violent turmoil, with planetesimals, asteroids, and comets smashing together and pelting the Earth, Moon, and the other inner planets with…

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…
