NASA’s Transiting Exoplanet Survey Satellite (TESS) is the first space-based, all-sky surveyor to search for alien worlds. The spacecraft was launched...
An international team of astronomers has discovered a hot rocky and a warm puffy super-Earth exoplanets orbiting the 7.5-billion-year-old star HD 15337.
An...
A team of planetary scientists at the Australian National University found that our planet is made of the same elements as the Sun but has less of the...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have discovered a planetary system containing at least three small planets, orbiting...
K-type dwarf stars are dimmer than the Sun but brighter than the faintest stars. These stars live a very long time — 17 billion to 70 billion years,...
A decade after its launch and months after its mission ended, glimmers of data detected by NASA’s Kepler Space Telescope in 2009 have been confirmed...
For several years, scientists have tried to explain why so many pairs of exoplanets have an odd configuration — their orbits seem to have been pushed...
Astronomers using data from NASA’s Transiting Exoplanet Survey Satellite (TESS) have discovered two ‘warm’ gas giants orbiting a nearby dwarf star.
An...
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...
