Astronomers using NASA’s Transiting Exoplanet Survey Satellite have discovered a sub-Neptune exoplanet orbiting TOI-220, a bright and old K-type dwarf...
Astronomers using the NASA/ESA Hubble Space Telescope have imaged a Jupiter-sized, still-forming planet around the orange dwarf star PDS 70. This is the...
Dark matter with masses below 1 GeV can scatter, become captured, deposit annihilation energy, and increase the heat flow within extrasolar gas giants,...
Astronomers using the Spectro-Polarimetric High-contrast Exoplanet Research (SPHERE) instrument on ESO’s Very Large Telescope have discovered and directly...
Kepler-34, Kepler-35, Kepler-38, Kepler-64 and Kepler-413 — multiple star systems located between 2,764 and 5,933 light-years away in the constellations...
A new study published in the Journal of Geophysical Research: Planets is a first step toward a generalized theory of how precipitation and condensible...
Using data from NASA’s Transiting Exoplanet Survey Satellite (TESS) and the HARPS-N spectrograph at the 3.6-m Telescopio Nazionale Galileo, astronomers...
Using data from NASA’s Transiting Exoplanet Survey Satellite (TESS) and several ground-based telescopes, astronomers have discovered and confirmed a...
1I/‘Oumuamua, a strange object of extrasolar origin discovered on October 19, 2017 by the Pan-STARRS 1 telescope, was small, about half as long as a...
Using the NASA/ESA Hubble Space Telescope, astronomers have found evidence of volcanic activity reforming the atmosphere of Gliese 1132b, a rocky exoplanet...
Five sub-Neptunes and one super-Earth exoplanet orbit a moderately bright K-type star called K2-138.
An artist’s impression of the six-planet system...
Astronomers have discovered evidence for a giant planet orbiting Vega, a young star located 25 light-years away in the constellation of Lyra.
An artist’s...
Astronomers from the CARMENES (Calar Alto high-Resolution search for M dwarfs with Exoearths with Near-infrared and optical Échelle Spectrographs) consortium...
LHS 3844b’s hemispheric tectonics is the direct consequence of a significant temperature contrast between its day- and nightside and is absent in the...
Radionuclides are ubiquitous in sediment and rock, where their decay leads to the production of hydrogen and oxidized chemicals via radiolysis of water;...
In a study published in the journal Science Advances, a team of European astronomers shows that water can be delivered to a terrestrial planet in the form...
A team of astronomers from Spain, Italy and Germany has discovered a short-period super-Earth exoplanet circling the nearby red dwarf Gliese 740.
An artist’s...
K2-290A, the primary star in the triple stellar system K2-290, is tilted by 124 degrees compared with the orbits of both of its known planets, and has...
