A team of astronomers in the United Kingdom has used a machine learning algorithm to analyze a sample of candidate exoplanets identified by NASA’s Kepler...
An international team of scientists has found interstellar iron-60, a radioactive isotope with a half-life of 2.6 million years that is predominantly produced...
A new image from the NASA/ESA Hubble Space Telescope shows a tiny portion of a nebula called the Cygnus Loop.
This Hubble image shows a small portion of...
Astronomers have observed cold, dense and high-velocity molecular gas outflowing from the center of our Milky Way Galaxy. The presence of this gas is puzzling,...
In a paper published in the Astrophysical Journal Letters, Harvard University astrophysicists Avi Loeb and Amir Siraj show that an equal-mass stellar companion...
Multiple supernova explosions about 65 light-years away may have contributed to the ozone depletion and several subsequent extinction events at the Devonian-Carboniferous...
A team of professional astronomers and citizen scientists from the Backyard Worlds: Planet 9 project has spotted 95 new brown dwarfs near the Sun.

‘Oumuamua, a recently-discovered cigar-shaped object of extrasolar origin, is not made of molecular hydrogen ice after all, according to a new study...
The red supergiant Betelgeuse is one of the brightest stars in the night sky and appears even more luminous because it is so close to Earth, only 650 light-years...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered an extremely distant galaxy that looks surprisingly like our...
On July 4, 2020, NASA’s Transiting Exoplanet Survey Satellite (TESS) completed its primary mission and is continuing its search for new extrasolar worlds.
An...
The heliosphere is a giant magnetic bubble that contains our Solar System, the solar wind and the solar magnetic field. Outside the heliosphere is the...
Astronomers using NSF’s Very Long Baseline Array, a continentwide system of 10 radio telescope antennas located between Hawaii and Puerto Rico, have...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered a giant set of spiral arms around the young variable star RU...
Astronomers using the FORS (FOcal Reducer and low dispersion Spectrograph) instrument on ESO’s Very Large Telescope (VLT) have obtained a stunning image...
The Phoenix stellar stream, a thin over-density of stars in the halo of our Milky Way Galaxy originally identified by the Dark Energy Survey, is composed...
Using ESA’s International Gamma-Ray Astrophysics Laboratory (Integral), NASA’s Neil Gehrels Swift Observatory and several radio telescopes, astronomers...
Astronomers from the Radial Velocity Experiment (RAVE) Collaboration have released a database of spectra and associated fundamental stellar parameters...
