Astronomers have discovered an exoplanet with several times the mass of the Earth orbiting a nearby star. A paper reporting this discovery is published...
For decades, astronomers have puzzled over the variability of young stars residing in Taurus-Auriga dark clouds, a group of molecular clouds located in...
Astronomers have discovered a giant gaseous planet orbiting a pair of brown dwarfs called 2MASS J02495639-0557352AB (2MASS 0249 for short). The new exoplanet,...
Understanding which chemical elements are present in a star in what abundances can help astronomers estimate the makeup of planets that orbit them, which...
Astronomers using the SPHERE instrument on ESO’s Very Large Telescope have found an infant gas giant orbiting the young dwarf star PDS 70. Not only have...
New research from the Georgia Institute of Technology and the Harvard-Smithsonian Center for Astrophysics suggests that exoplanets Kepler-62f and Kepler-186f...
A team of leading astronomers, biologists and geologists have come together under the Nexus for Exoplanet System Science (NExSS), a NASA research coordination...
The NASA Kepler spacecraft’s reborn K2 mission announced this week the discovery of 78 new potential exoplanets: 30 high-quality planet candidates and...
An extrasolar planet larger than the Earth has been discovered orbiting a nearby cool star, thanks to data gathered by NASA’s Kepler/K2 mission.
Artist’s...
An international team of astronomers from the United States, Australia, and Brazil has identified 121 giant exoplanets in the habitable zones of their...
