An international team of astronomers has found a ‘super-Earth’ exoplanet orbiting HD 285181, a 3.7-billion-year-old solar-type star approximately 294...
Astronomers using data from NASA’s Kepler Space Telescope have discovered a planet roughly twice the size of Earth orbiting a star in the low-mass binary...
NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered its third small exoplanet, named HD 21749b. The discovery will be reported in a paper...
Astronomers have discovered a frozen exoplanet nearly the size of Neptune orbiting the quiet G9-type dwarf star K2-263.
An artist’s impression of the...
Extrasolar ‘Neptunes’ are exoplanets with masses and radii similar to those of the ice giants in the Solar System. In 2015, astronomers using the NASA/ESA...
While observing a massive protostar called G11.92-0.61 MM 1, a research team led by University of Leeds astronomers discovered it was not in fact one stellar...
An international team of astronomers has detected helium escaping from the upper atmosphere of HAT-P-11b, a Neptune-mass exoplanet located in the constellation...
Astronomers using data from NASA’s Transiting Exoplanet Survey Satellite (TESS) have discovered a hot-Jupiter exoplanet orbiting the early F-type star...
Astronomers using the Near-Infrared Spectrograph (NIRSPEC) on the Keck II telescope at the W. M. Keck Observatory have confirmed the existence of water...
A potentially rocky super-Earth orbits one of our closest stellar neighbors, Barnard’s star, only 6 light-years away.
An artist’s impression of Barnard’s...
Astronomers using the Spectro-Polarimetric High-contrast Exoplanet Research (SPHERE) instrument on ESO’s Very Large Telescope (VLT) have captured a series...
A new study, published in the Astrophysical Journal, suggests that if a 1- to 2-megawatt (MW) laser were focused through a 30- to 45-m telescope and aimed...
NASA’s Kepler Space Telescope, which spent nine years in deep space collecting data that detected thousands of exoplanets, has run out of fuel needed...
A team of U.S. astronomers has discovered that small planetary systems with multiple planets are more likely to form around stars that have lower amounts...
Stellar superflares from young red dwarfs may make conditions uninhabitable on fledgling planets, according to the new results of the Habitable Zones and...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered a 2-million-year-old planetary system containing at least four...
Astronomers using the NASA/ESA Hubble Space Telescope and NASA’s Kepler Space Telescope have assembled compelling evidence for the existence of a large...
Astronomers have discovered a ‘super-Earth’ exoplanet orbiting a Sun-like star 473 light-years from Earth.
An artist’s impression of the super-Earth...
