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 ...

A distant Sun-like star began dimming unpredictably, prompting astronomers to investigate what was blocking its light.

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 ...

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

It provides a dynamic, time-resolved view of planetary transformation, a missing link between young inflated worlds and the compact sub-Neptunes that populate the galaxy.

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