Could there be life on other worlds? Scientists believe that distant moons far beyond our galaxy hold the answer.
Astronomers may have a weather forecast for a planet far beyond our solar system. Using sensitive observations from the Kepler space telescope, scientists have uncovered daily weather cycles on six extra-solar planets.
A newly discovered exoplanet may be too big for its star. Scientists have discovered a strange exoplanet orbiting a small cool star about 500 light-years away that's challenging ideas about how planets forms.
Ever wanted to name a planet? Now you may have your chance. A total of 20 of the most popular exoworlds have been made available for naming proposals from registered clubs and non-profit organizations.
Astronomers have made a startling discovery in a nearby galaxy. They've found a planetary system orbiting a star that's only 54 light-years away; all three of the planets are "super Earths."
The hunt for alien life continues, but one planet may not be as hospitable to life as scientists once believed. Researchers have examined our cosmic neighbor, Tau Ceti, and have found that the system is unlikely to host life.
Astronomers have spotted the first ever exoplanet in the visible light spectrum. The exoplanet, called 51 Pegasi b, is located just 50 light-years from Earth in the constellation of Pegasus.
Astronomers have uncovered the inner region of a young star and its planets located 130 light-years from Earth.
Researchers have taken a closer look at the interplay between planets and stars, and have found that stars may actually rip oxygen from potentially habitable planets, making them unlivable.
Astronomers have discovered an exoplanet with a truly terrifying atmosphere.
Luke Skywalker's home planet, Tatooine, may actually be common in the universe. Scientists have found that rocky, desert planets with twin suns may be widespread.
