About 3.5 million years ago, a Seyfert flare from Sagittarius A*, a supermassive black hole in the center of the Milky Way Galaxy, created two enormous...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have discovered an intermediate-mass brown dwarf orbiting a young star about 841...
Astronomers have discovered a hot-Jupiter exoplanet so close to its host star, called NGTS-10, that a year on that planet lasts only 18.4 hours, making...
NASA’s Spitzer Space Telescope has imaged an active star-forming region in the constellation of Aquila. The region is full of cosmic bubbles, which are...
A new study by astronomers from the A. Mickiewicz University and the Space Research Centre of the Polish Academy of Sciences suggests that the interstellar...
Using data collected by the NASA/ESA Hubble Space Telescope, astronomers have created the deepest ever catalog of variable sources (variable stars in our...
A team of astrophysicists from Columbia University proposes that the strange long-term dimming of the KIC 8462852 star (also known as Tabby’s star or...
Astronomers using the MeerKAT telescope at the South African Radio Astronomy Observatory have spotted a pair of enormous radio-emitting bubbles in the...
A runaway star called PG 1610+062 was probably ejected from the Milky Way’s Carina-Sagittarius spiral arm at a velocity of 341.8 mi/s (550 km/s) with...
Astronomers from the Red Dots Collaboration have detected three rocky exoplanets orbiting Gliese 1061, which is the 20th nearest star to the Sun. The outermost...
Astronomers using data from ESA’s Gaia spacecraft have identified a number of clusters, associations and co-moving groups of stars within about 3,300...
A volcanically active rocky exomoon may orbit WASP-49b, a hot gas giant approximately 550 light-years away in the constellation of Lepus.
An artist’s...
The temperature on the nightsides of short-period gas giants (hot Jupiters) is surprisingly uniform, suggesting the dark sides of these exoplanets have...
Using data from ESO’s High Accuracy Radial Velocity Planet Searcher (HARPS) instrument, a multinational team of astronomers has uncovered evidence for...
A team of researchers from Germany, Austria and Australia has found traces of the radioactive isotope iron-60 — the tell-tale signature of a supernova...
Pulsars are rapidly rotating neutron stars observed to have pulses of radiation at very regular intervals that typically range from milliseconds to seconds....
An international team of astronomers from the United States, Germany and Israel has discovered a new class of pulsators that vary in brightness every 5...
SMSS J160540.18-144323.1, an ultra-metal-poor red giant star located in the halo of the Milky Way, on the other side of the Galaxy about 35,000 light-years...
By measuring the distance from the Sun to thousands of classical Cepheid stars and the associated young stellar populations scattered across the Milky...
