Astronomers have used a new technique to measure — for the first time — the spin of an extrasolar planet.
Exoplanet missions are shifting their goals from counting to characterizing, with multiple instruments coming online to directly image these alien worlds.
With exoplanet Ross 128b in the news, we pay a visit to the star that sustains this potentially habitable exoplanet.
Following a wildly popular contest, the International Astronomical Union has named 14 stars and 31 planets that orbit them.
By combining nearly 1,500 observations with sophisticated computer models, astronomers have shed light on a nearby planetary system, proving that the planets' bizarre orbits will actually remain stable for the next 100 million years.
Researchers have found that a football-shaped, ultra-hot gas giant that’s being devoured by its host star is also one of the least reflective exoplanets ever found.
Data from NASA's Kepler space telescope point to three distinct molds of exoplanets — rocky worlds, gas dwarfs, and ice/gas giants — distinguishable based on the abundances of heavy elements in their host star’s atmosphere.
