Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have discovered a planetary system containing at least three small planets, orbiting...
Hypervelocity stars are solitary stars moving fast enough to escape the gravitational grasp of the Milky Way Galaxy. Discovered in 2014, LAMOST-HVS1 is...
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,...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have spotted streams of molecular gas orbiting around an invisible gravitational...
Astronomers using the NASA/ESA Hubble Space Telescope have observed the massive, luminous globular cluster NGC 2419, also known as the ‘Intergalactic...
Professional astronomers and volunteers working with the Backyard Worlds: Planet 9 citizen science project have spotted the oldest and coldest known white...
Astronomers using ESA’s Gaia satellite have discovered a large stellar stream that is currently traversing the immediate solar neighborhood at a distance...
A duo of astronomers has spotted three new globular clusters in the Milky Way’s bulge, a 10,000-light-year-wide central structure made primarily of old...
Astronomers using the NASA/ESA Hubble Space Telescope have discovered a new dwarf galaxy in our cosmic neighborhood. Named Bedin 1, the galaxy is approximately...
A team of astronomers from the Space Telescope Science Institute and the Institute for Astronomy at the University of Hawaii has released data from the...
Astronomers using ESA’s galaxy-mapping spacecraft Gaia have discovered the first direct evidence that white dwarfs form crystal cores of metallic oxygen...
The Large Magellanic Cloud, a dwarf galaxy located approximately 163,000 light-years away, is on a collision course with the Milky Way with which it will...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have spotted comet-like stars in a young star cluster called Westerlund 1.
This...
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 ESO’s Very Large Telescope have observed an elaborate serpentine system sculpted by colliding stellar winds. The object, called 2XMM...
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...
Astronomers using data from ESA’s Gaia satellite have discovered a new dwarf satellite galaxy of the Milky Way. The dwarf galaxy, named Antlia 2, is...
A new study, published in the Astrophysical Journal, suggests that if a 1- to 2-megawatt (MW) laser were focused through a 30- to 45-m telescope and aimed...
