The discovery is the first evidence supporting the hypothesis that very low-mass, low-temperature stars should have Earth-sized or smaller planets orbiting them.
By studying reflected light from a young star system, astronomers have precisely measured the size of the innermost gap between the star and where planets will eventually form.
Computer analysis of the wobble of a nearby star may have turned up evidence for a small, Earth-sized world -- but don't get too excited about it being habitable.
Long before the first confirmed planetary finds in the 1990s, an observer in 1917 caught evidence of planetary debris around a new star, new research into an astronomical glass plate reveals.
Scientists have discovered radioactive debris from relatively nearby stars that exploded a few million years ago, raising questions about whether cosmic rays released by the supernovae impacted Earth’s past climate.
An exoplanet has been discovered in a very strange star system more bizarre than most science fiction storylines.
Where DO baby planets come from? Well, this observation of a young star sporting a ringed protoplanetary disk holds the answer.
Roughly 7 percent of the Milky Way's red dwarf stars live in the outer reaches of the galaxy.
