SUNSET: 
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.
Astronomy in Pictures: Saturn and the Milky Way
The James Webb Space Telescope offers a new view of Saturn, while the IceCube Observatory creates a neutrino-painted picture of the Milky Way.

See Summer's Best “Gobbled” Globulars
Mergers between the Milky Way and long-ago dwarf galaxies have enriched our skies with dozens of iconic globular clusters. Many are visible in small telescopes.
Watch the Milky Way’s Black Hole Spaghettify a Cloud
Two decades of observations show a dusty gas cloud elongating as it approaches our galaxy's supermassive black hole.
Amateur Astronomers Find Glowing Gas Arc Near Andromeda
An arc that glows green thanks to doubly ionized oxygen appears near the Andromeda Galaxy in a photo obtained by amateur astronomers.
A 3D Magnetic Map of the Local Bubble
Astronomers have mapped the magnetic field along the "bubble" of gas 1,000 light-years wide around the Sun.
Speeding Cloud Might Come from Recent, Nearby Supernova
Hypervelocity clouds, generally thought to be falling fast into the Milky Way, might have an alternative explanation that places them near us.
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.
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!
Have We Found the First Rogue Black Hole in the Milky Way?
Hubble observations have revealed a stellar-mass compact object — a black hole or possibly a neutron star — wandering our galaxy.
Hundreds of Thousands of Stars Reveal the Milky Way’s “Teenage” Years
A census of hundreds of thousands of subgiant stars in our galaxy provides a window into the Milky Way's early history.
A Star Where It Shouldn't Be
There’s a massive star in our galaxy’s halo, far away from the usual star-forming haunts. How did it get there?
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.
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.
Stellar Streams Are Revealing Their Secrets
A detailed study of 12 streams of stars swirling in and around the Milky Way will ultimately help shed light on our galaxy's dark matter halo.
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.
Tiny Galaxy’s Giant Black Hole Throws Astronomers for a Loop
A satellite galaxy dwarfed by the Milky Way has a black hole nearly as massive as the one at the center of our galaxy.
How Our Largest Dwarf Galaxy Keeps the Others In Line
New research may explain why satellite galaxies align themselves around the Milky Way
Astronomy in Pictures: Black Holes, Baby Stars, and Magnetic "Tunnels"
Astronomers witness the unfurling of a black hole-powered mushroom cloud, a baby super-Jupiter, and a magnetic "tunnel" around the solar system.
Take a Deep Look into the Milky Way Halo
New analysis shows the best view of the Milky Way halo to date, providing a window into our galaxy's future star formation.
