In celebration of the 30th anniversary of the launch of the NASA/ESA Hubble Space Telescope, astronomers used the telescope to take a portrait of the giant...
Comets spend most of their lives at large distances from any star, during which time their interior compositions remain relatively unaltered. Cometary...
Clusters of supernovas can cause the birth of scattered, eccentrically orbiting stars in outer halos of Milky Way-mass galaxies, according to new research...
Astronomers using data from NASA’s Kepler Space Telescope have discovered an Earth-sized planet in the habitable zone of a low-mass star called Kepler-1649.

A due of researchers used numerical simulations to show that interstellar objects like ‘Oumuamua, a fast moving, cigar-shaped object of extrasolar origin...
Gamma-ray bursts are the most energetic explosions in the Universe, beaming out huge jets of light-emitting plasma, which travel through space at 0.99...
Astronomers using the CARMENES spectrograph at Calar Alto Observatory in Spain have discovered a super-Earth exoplanet orbiting an M-dwarf star in the...
A bright X-ray source in a massive star cluster in the outskirts of 6dFGS gJ215022.2-055059, a barred lenticular galaxy located about 806 million light-years...
Using data from the Atacama Large Millimeter/submillimeter Array (ALMA), a team of astronomers has found striking orbital geometries in circumbinary protoplanetary...
Astronomers using the NASA/ESA Hubble Space Telescope have captured a stunning image of a huge HII region called LHA 120-N 150. This bright pink cloud...
Astronomers have spotted a pulsating white dwarf star in the binary stellar system SDSS J115219.99+024814.4 (SDSS J1152+0248 for short).

WASP-76b, a gas-giant exoplanet located some 640 light-years away in the constellation of Pisces, has a day side where temperatures climb above 2,400 degrees...
Using data from NASA’s Transiting Exoplanet Survey Satellite (TESS), a team of professional astronomers and citizen scientists has discovered a star...
On February 15, 2020, a team of U.S. astronomers observed Betelgeuse, a dimming red supergiant located approximately 650 light-years away from Earth, using...
W43A, an aged star located some 7,000 light-years away in the constellation Aquila, ejected high-speed bipolar jets less than 60 years ago, according to...
Super-puffs, an intriguing, growing class of exoplanets, are the objects with exceptionally large radii for their masses and thus correspondingly low densities....
