Amid the COVID-19 pandemic, native Hawaiians who oppose construction of the Thirty Meter Telescope (TMT) project on Maunakea in Hawaii have reduced their presence on the mountainside.
A recent study went full Indiana Jones to show that our home galaxy, the Milky Way, was a cannibal in its earlier years, swallowing five smaller galaxies.
The Milky Way's warped shape probably is due to a long-running collision with a smaller galaxy. But which galaxy this might be is a mystery.
There are at least two bright spots in these strange times: Telescopes are still studying distant galaxies and penguins are still pooping across Antarctica.
The neutron-star merger that showered the solar system with its precious metals was fairly close and fairly recent.
In six studies published March 16 in a special edition of The Astrophysical Journal supplemental series, astronomers used NASA's Hubble Space Telescope to spy on 13 quasar outflows.
A distant globular cluster that's home to dozens of fast-rotating stars could provide new clues about the formation of the Milky Way and the gas halo that surrounds the galaxy.
The red supergiant star Betelgeuse is nearing the end of its life, and researchers are preparing for what it will look like when the star explodes in a supernova.
Astronomers have finally found something they have spent decades searching for: a teardrop-shaped star that pulsates on only one side.
Astronomers scouring the cosmos for new planets have made a chance discovery, identifying the rare eclipse of two brown dwarfs.
A bright, red star that started dimming dramatically in 2019 isn't about to explode, as some scientists initially thought — it's just really dusty, a new study shows.
Looking for life traditionally starts with finding a planet with the right temperature — but scientists are working to find new criteria for tracking down potentially habitable worlds.
A giant white dwarf star may be the offspring of a collision between two other white dwarfs, a new study finds.
Astronomers have imaged more than 300 newborn stars, revealing new clues about the early stages of star formation and the birth of planets.
A volatile double star system appears to change its behavior rapidly and unpredictably like a cosmic story of Dr. Jekyll and Mr. Hyde.
Stars don't see gender, and now, NASA is working to not see it either when allocating telescope time to scientists, inspired by a successful experiment with the Hubble Space Telescope.
