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 ...

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 ...

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 ...

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 ...

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 ...

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 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. Using data from NASA’s James ...
