Is anybody home? Astronomers have pinpointed two planets orbiting a nearby star that meet pretty much every requirement for supporting life. They're almost exactly the same mass as the Earth, they are billions of years old (which means life could have had time to evolve), and they're orbiting their star at a distance that would support things like water flow and habitable temperatures.

Help name a planet in our solar system

It's been 10 years since the largest unnamed minor planet in our solar system was discovered. Yet it has remained nameless, apart from the identifier 2007 OR10.

Frozen super-Earth discovered six light-years away

Astronomers have found a frozen exoplanet more than three times the mass of Earth, orbiting a star that's only six light-years away. The exoplanet is orbiting Barnard's star, the closest solitary star to our sun.
