If you're feeling all tied up with obligations this holiday season, perhaps a newly studied galaxy feels the same way.
Gas halos surround some of the earliest galaxies in the universe, providing a reservoir of cool gas that fuels the growth of supermassive black holes.
Astronomers have captured the first image of the most distant star-forming galaxy ever observed with a telescope.
What do Van Gogh's "Starry Night," traditional Ethiopian coffee ceremonies and a river in Alaska have in common? All are now commemorated in the solar systems around ours.
Astronomers gazing into the heart of the Milky Way have discovered new clues about our galaxy's dramatic past.
Scientists have created the first "hotspot" map of the surface of a strange star, thanks to a telescope on the International Space Station.
For the first time, a Polish group has identified two nearby stars that seem to have plucked up their icy partners, swinging them into orbits around our sun.
Scientists have spotted an incredibly weird, 'impossible' white dwarf star in a discovery that suggests these objects are even more common than suspected.
Nineteen newly discovered dwarf galaxies seem to be missing their dark matter, and physicists aren't sure why.
For the first time ever, astronomers have spotted evidence of a planet circling a superdense stellar corpse known as a white dwarf, a new study reports.
Hoag's object, which is a galaxy within a galaxy within a galaxy, has befuddled stargazers since astronomer Arthur Hoag discovered it in 1950.
In a quiet orbit around the far side of the moon, three radio antennas are now outstretched, craning for whispers from a mysterious period early in the universe's history.
While black holes are famously known for devouring any matter that gets too close, these cosmic behemoths may have a nurturing side, too.
In 1987, a star exploded, creating the brightest supernova to light up Earth's skies in 400 years. That star's corpse has been missing for 30 years. Now, researchers think they've found it.
An international team of scientists has created the most detailed large-scale model of the universe to date, a simulation they call TNG50.
Gamma-ray bursts, the most powerful kinds of explosions known in the universe, can generate even more energetic light beams than astronomers previously realized, according to a set of new studies.
This week, the variable star Mira reaches its highest point, roughly halfway up in the southern sky at around 10 p.m. local time.
An intervening cluster of galaxies acts like a cosmic microscope and bends and magnifies light from a distant galaxy.
