The Hubble Space Telescope has been used to study 25 hot Jupiters. It has helped to answer "questions important to our ...

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 ...

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 ...

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 ...

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 ...

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 ...

"It was just a matter of time before we found them." Thirty years ago, on Oct. 6, 1995, the very first exoplanet to be discovered around a sun-like star was revealed. Called 51 Pegasi b, it was a ...

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 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 ...
