Earth-sized worlds around a small star might be habitable after all.
We’ve thought that young planets form gaps in the planetary disks of young stars. Now we find that these gaps can form without the presence of planets.
Jupiter-type planets come in two sizes, and these two types of planets formed in very different ways.
Just 10 light years away, Epsilon Eridani is a young star system that tells us how our own solar system may have formed.
Habitable Tatooine-like worlds with two suns are theoretically possible.
Astronomers have found a rich atmosphere around an Earth-sized planet, and that means potentially habitable worlds could exist around red dwarf stars.
The binary star system SDSS 1557 has a rocky asteroid belt, which could hold clues to the formation of Earth-like planets.
Early planets can form from clumps of dust.
Astronomers have found seven Earth-sized planets around a dwarf star. Here’s how they did it.
