Galactic Archaelogy in the Milky Way Halo

The motions of thirteen stars in our galaxy’s halo outline a shell-like structure, perhaps the remains of an ancient galactic collision.

A Cold New View of the Milky Way Galaxy

A stunning submillimeter mosaic of the Milky Way Galaxy captures a portrait of the cold dust and gas swirling along the galactic plane.

A Galaxy Hit-and-Run

Ripples found in the Milky Way’s disk reveal our galaxy survived an ancient hit-and-run. Now, astronomers might have caught the culprit.

Milky Way

Our “Magnetic” Black Hole

Astronomers have detected magnetic fields writhing around the Milky Way's central black hole.

Star-Counting in the Galactic Bulge

Astronomers have taken a careful census of the smallest stars in our galaxy’s center.

Milky Way: Young Stars in an Old Bulge

The presence of stars just 100 million years old in the Milky Way Galaxy’s central regions confirms our galaxy’s nonviolent past.

Buckyballs Solve Interstellar Mystery

Soccer ball-shaped molecules lurking in the dusty corners of the Milky Way help resolve a long-standing problem.

Witnessing Light Echoes from a Neutron Star

X-ray echoes from binary star system Circinus X-1 are helping astronomers measure its distance from Earth.

Mapping the Milky Way with embedded star clusters

Mysterious X-rays Spotted in Galactic Center

NASA’s NuSTAR mission has detected an unexpected haze of high-energy X-rays in our galaxy’s center, perhaps the signal of a mass stellar graveyard.

Ripples in the Milky Way

Astronomers have detected what look like four undulations in the Milky Way Galaxy’s disk. If the structures are all part of the disk, our galaxy is more than half again as large as we thought it was.

G2 Survives Black Hole Pass

The gaseous object G2 has survived its swing around the Milky Way’s central supermassive black hole, but the questions of what it is and where it comes from remain unanswered.

Laniakea: Our Home Supercluster

Astronomers have mapped the cosmic watershed and discovered a massive supercluster that extends more than 500 million light-years and contains 100,000 large galaxies. The Milky Way sits on the edge of this humongous structure.
