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 ...
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 ...
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 ...
A team of astronomers from the University of Montreal has discovered a new potentially habitable exoplanet orbiting the red dwarf star L 98-59, 35 light-years from Earth. This discovery means there ...
Using the Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new exoplanet orbiting a nearby star. The newfound alien world, designated TOI-2431 b, is ...

Exoplanet atmosphere contains oxygen, NASA says
In a significant leap forward in the quest for extraterrestrial life, NASA recently announced the detection of oxygen in the atmosphere of an exoplanet. This revolutionary discovery will be the ...
Exoplanets are planets outside Earth's solar system. In 1995, a gas giant named 51 Pegasi b, which orbits a star similar to Earth's sun, etched its name in history as the first exoplanet ever ...

Exoplanet 15 light-years away has gravity
Recently, an exoplanet just a short 15 light-years from Earth was discovered, setting the scientific community abuzz. This newly found celestial body boasts a unique gravitational pull, a feature that ...
Just decades after the first exoplanets were identified, our database of the distant worlds—monitored by the NASA Exoplanet Science Institute—has breached a new threshold. Now, astronomers have ...
"Lava planets are in such extreme orbital configurations that our knowledge of rocky planets in the solar system does not directly apply." Astronomers may be starting to get the goods on lava planets.
Astronomers using the James Webb Space Telescope (JWST) have reported a potential detection of a Saturn-like exoplanet orbiting Alpha Centauri A: the closest Sun-like star to Earth, located just over ...
