Learn about the first images of low-mass stars captured by SPARCS, a nanosatellite that could provide insight into exoplanets ...

Finding Earth-like planets orbiting sun-like stars and identifying signs of life such as oxygen or water is a major goal in ...

Astronomers have witnessed evidence of an extremely violent collision between planets, and it resembles the event in Earth's history that created the moon.

Astronomers have found an exoplanet that could serve as a benchmark in future studies. It's a rocky planet orbiting an M-type star, and though these planets are plentiful, this one could serve as a ...

In old measurement data, two US researchers found a star that appeared "completely crazy." Apparently, there was a ...

If you examine our solar system’s giant planets, you’ll notice right away that they’ve all got moons—a lot of moons. While Earth only has the one, Jupiter has about 100 that we know of (and likely ...

A new study shows that stars with low magnetic activity are likely to support exoplanetary systems, making the hunt for these ...

NASA researchers explore a hybrid observatory using a space-based starshade and ground telescopes to improve direct imaging and detect hidden Earth-like exoplanets.

They were too big and too far away to exist by the rules. Now, using the James Webb Space Telescope (JWST), an international team of astronomers has finally cracked the chemical code of these distant ...

Although astronomers have found thousands of exoplanets, the number of confirmed exomoons—and exorings—is still zero. But that may soon change ...

NASA has received the first images from a tiny spacecraft designed to study the ...
