By studying hot gas glowing in circumgalactic space, astrophysicists have found evidence of enormous magnetic fields that wind through and around our galaxy's dark matter 'halo'.
A fluffy cluster of stars spilling across the sky may have a secret hidden in its heart: a swarm of over 100 stellar-mass black holes.
The study suggests Sagittarius A* likely formed through a merger with another black hole, explaining its spin and misalignment.
Look hard enough at the roiling mist of gas and starlight that is our galaxy, and you'll find traces of a violent upbringing.
For years, astronomers thought it was the Milky Way’s destiny to collide with its near neighbor the Andromeda galaxy a few billion years from now. But a new simulation finds a 50% chance the impending crunch will end up a near-miss.
Astronomers have found evidence for an intermediate-mass black hole in IRS 13, a population of dusty stellar objects within the nuclear star cluster of our Milky Way Galaxy.
The two new satellites, named Virgo III and Sextans II, were discovered in a region of space already crowded with more dwarf galaxies than models of dark matter predict.
The Milky Way is only as massive as it is because of collisions and mergers with other galaxies.
A study of the stars crashing around in the Milky Way's galactic center suggests that they are much, much older than they appear – and that their youthful good looks are the result of cosmic cannibalism.
A new image from the Event Horizon Telescope (EHT) collaboration has uncovered strong and organised magnetic fields spiraling from the edge of the supermassive black hole Sagittarius A* (Sgr A*).
A search for the first stars that winked into existence at the dawn of the Universe has yielded one of the oldest stars we've found yet, right next door to our own galaxy.
Towards the center of the galaxy, two streams of stars nearly as old as the Universe have been discovered circling the heart of the Milky Way. These two streams have been named Shiva and Shakti.
A few years ago, astronomers uncovered one of the Milky Way's greatest secrets: an enormous, wave-shaped chain of gaseous clouds in our sun's backyard, giving birth to clusters of stars along the spiral arm of the our galaxy.
The discovery of phosphorus in a molecular cloud at the edge of the Milky Way galaxy extends the presence of the element almost twice as far out as where it was known to exist.
Every 76 minutes, like clockwork, the gamma-ray flux of Sagittarius A*, the supermassive black hole in our galaxy, fluctuates, suggesting an orbital motion of something whirling madly around the black hole.
