Astronomers studying a faint red dwarf star called LHS 1903 have found a four-planet system arranged in a sequence that no standard model of planet formation predicted. The system follows a ...

Up until now, exoplanet surveys have mostly focused on nearby, bright stars that are sun-like or are red dwarfs, which are known to frequently host planets. While astronomers have discovered thousands ...

Scientists might have just found Earth's icy, distant cousin a few hundred million light-years away. HD 137010 b is one of ...

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.

What can carbon dioxide in an exoplanet’s atmosphere teach us about its formation and evolution? This is what a recent study published in The Astrophysical Journal hopes to address as an international ...

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

A team of scientists has confirmed that the nearby star GJ 887 hosts at least four planets, one of which could be a habitable ...

Astronomers have collected evidence of a violent collision between two planets in a distant star system. The first clues of this cataclysmic event came when a rather boring star began behaving very ...

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 ...

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 ...

As part of the Decadal Survey on Astronomy and Astrophysics (Astro2020), the Panel on Exoplanets, Astrobiology, and the Solar System will identify and articulate the scientific themes that will define ...

Three hundred and forty light years from Earth, there burns a triple star system lighting a planet unlike any other world we've ever seen. What might you see, if you could go there and look up at its ...
