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...
2MASS J18082002-5104378 B, an ultra metal-poor star located some 1,950 light-years away from Earth, is approximately 13.53 billion years old, making it...
