Exoplanet Beta Pictoris b can be seen moving around its star in this 17-year timelapse created using "AI-driven ...

In our solar system, Earth is one of but eight planets – nine, if you really want to count Pluto – and the only one remotely hospitable to life. And as technology advances, astronomers only expect to ...

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 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 ...

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 ...

Observations of Exoplanet WASP-69b has uncovered a 350,000-mile-long comet-like tail. The tail is a result of its escaping ...

The team of astronomers behind the find suggested it could help us better understand planet and moon formation in our solar system and beyond the Milky Way. The team was able to make the first-ever ...

"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 ...

When the JWST finally began its long-awaited science operations in July 2022, there was a long list of targets awaiting its attention. Scientists compete for observing time by submitting proposals, ...

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 ...

In principle, discovering new exoplanets is pretty easy. Simply measure the brightness of a star over time, and when a planet passes in front of the star, the brightness will dim slightly. The more ...

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 ...
