In a significant breakthrough, scientists have identified three Earth-sized exoplanets in a binary star system, potentially ...

Scientists are observing an Earth-like exoplanet that may contain water using NASA's James Webb Space Telescope, the space agency said in a news release. The exoplanet, known as TRAPPIST-1 e, orbits ...

Scientists have gotten a never-before-seen look at an area around a large exoplanet 625 light-years away where moons like the one orbiting Earth could potentially form. "Moons likely outnumber planets ...

Detecting exoplanets at all is difficult—they typically emit much less than 1% of a host star's brightness. Eclipse mapping requires measuring small fractions of that total as a planet circles behind ...

Astronomers might be close to confirming the presence of an Earth-like atmosphere on an exoplanet for the first time, if more detailed analyses verify preliminary observations from the James Webb ...

With the discovery of ever more exoplanets—over 6,000 now—scientists, of course, want to know if they are habitable for life. (At least, life as we know it.) But assessing habitability is a difficult ...

Astronomers have a new theory about planetary formation, and it revolves around one mysterious concept: interstellar visitors. No, not little green men, but rather deep-space wanderers like the ...

How many planets outside our solar system, known as exoplanets, exist throughout the Milky Way Galaxy? While that might never be determined, NASA recently announced the total number of confirmed ...

"This is the strongest accretion episode ever recorded for a planetary-mass object." Scientists have identified a lone planet with a ferocious appetite. Located in the Chamaeleon constellation roughly ...
