Milky Way

Our 13 billion-year-old galaxy has gone through many growing pains — usually to the detriment of its smaller neighbors.

An uncharted region of space known as the "zone of avoidance" lurks behind the Milky Way's center – and astronomers just found an enormous, multi-galaxy structure there.

Scientists found the ancient core using data from the Gaia spacecraft

Where are all the galaxy's dead stars hiding? New research draws the map.

New research suggests that a strange 'ripple' is causing the Milky Way's stars to vibrate out of step, and an ancient collision with Sagittarius may be to blame.

A large star surrounded by a spiral-shaped disk of dust could be the result of an ancient near-miss collision at the Galactic Center.

Astronomers have directly measured the mass and velocity of an isolated black hole for the first time using gravitational lensing.

Astronomers have created the most detailed map yet of the magnetic field within one of the Milky Way's galactic bones.

Astronomers have found that part of the MIlky Way known as the thick disk is about 2 billion years older than expected, forming just 0.8 billion years after the Big Bang.

A relatively small pulsar (a dense, collapsed and rapidly-spinning star) belched out a giant filament containing matter and antimatter particles that streamed for trillions of miles.
