What can Earth-sized exoplanets teach scientists about the formation and evolution of exoplanets throughout the cosmos? This is what a recently submitted study hopes to address as an international ...

Close stellar encounters could change the structure of our planetary system, potentially dooming Earth or other worlds to ...

Astronomers already know of real stars on paths that could bring them dangerously close to our solar system. One of them, Gliese 710, is expected to pass through the outer edge of the Oort Cloud ...

NASA launched two 12-inch gold-plated copper disks filled with the sounds of children's laughter, heartbeats, and bird calls.

The nearby star Gliese 229 harbours a ‘brown dwarf’ companion: an object less massive than a star but more massive than a planet. High-resolution observations reveal that it is two objects ...

Gliese 229 B, discovered in 1995, has long stumped scientists. Now, we know why — it is a binary system of two brown dwarfs orbiting each other, in orbit around their parent red dwarf star.

Beyond our solar system, countless alien worlds of lava, ice, water and noxious gas swirl through the cosmos. Here are some of the strangest exoplanets that scientists have discovered so far.

NASA announced the discovery of a planet 40 light years from Earth that orbits every 12.8 days and is possibly even habitable. Gliese 12 b is a "super Earth exoplanet" that is nearly the same size ...

Studying Gliese 12 b could help us understand why this is the case. "Gliese 12 b could teach us a lot about how our own solar system has developed as well," Palethorpe added.
