Rethinking the Milky Way’s “Galactic Fountain”

The Milky Way recycles gas from dying stars to make new ones — but new observations show pristine gas also comes in from outside our galaxy.

Astronomers Find Stars Cast Away from Galactic Neighbors

After decades of searching, scientists have found stars accompanying the gas streaming from two smaller galaxies that orbit our Milky Way.

Astronomers Map the Milky Way's "Underworld"

A simulated map of the Milky Way shows the location of our galaxy's stellar corpses — and they're not where you might think they'd be.

A Worthy Challenge in Orion

Milky Way

Supernovae Swept Out Barnard's Loop in Orion

Astronomers have mapped Orion in 3D to understand the origin of the large arc of Barnard’s Loop — and you can interact with the 3D image!

Astonishing Radio View of the Milky Way’s Heart

A new radio survey reveals a complex and chaotic galactic center teeming with supernova remnants, star-forming regions, and mysterious filaments.

Local Bubble lined with stellar nurseries

Milky Way

1,000-light-year "Bubble" Is the Source of All Nearby Baby Stars

Supernovae that carved out the Local Bubble, a cavity around the Sun, have also triggered star formation at the bubble's edges.

Astronomers Discover Celestial Ruins on Our Galaxy’s Edge

A stream of stars scattered across 15 degrees of sky was once part of a globular cluster torn apart by our galaxy’s gravity. The stars represent some of the oldest in the Milky Way.
