SUNSET: 
Milky Way’s Chances of Hitting Andromeda Galaxy May Be 50/50
A new analysis of Hubble and Gaia data suggests that our galaxy might survive an upcoming encounter with the Andromeda Galaxy unscathed.
The Milky Way Returns to the Night Sky in a Tide of Starlight
The summertime Milky Way ascends in the east on May nights. Find a dark sky and let it take you away!
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.
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.
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.
Reveling in the Winter Milky Way
With the Moon departing the evening sky, now's a good time for a closer look at the northern winter Milky Way and its southern summer counterpart, too. No equipment required!
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.
The Milky Way’s Local Arm Is Longer Than We Thought
New maps of the Milky Way suggest the Local Arm that we call home is longer than expected — now upgraded to a major spiral feature (but not quite an arm).
What — and Where — Is the North Polar Spur?
Astronomers make the case that a gigantic ridge of gas sticking out of the galactic plane was blown out by a cluster of nearby supernovae.
Astronomers Discover Galactic “Fossil” Inside the Milky Way
Thousands of stars that once belonged to an ancient galaxy are inside our own.
Star Clusters Reveal the "Kraken" in the Milky Way's Past
Astronomers have reconstructed the Milky Way's merger history, finding that our galaxy has absorbed five large satellite galaxies in the last 12 billion years.
Close Encounters in the Milky Way — and What They Mean for Planets
New research shows stellar flybys are common in our galaxy’s crowded center. That could have both good and bad (but mostly bad) effects on growing planets.
The 10 Million-Degree Gas Around the Milky Way
New observations show ultra-hot gas around the Milky Way. Stellar explosions may have driven this gas out of our galaxy.
Magnetism Rules in the Milky Way’s Core
Recent observations from the airborne SOFIA observatory show that magnetic fields — not gravity — govern the gas at the center of the Milky Way.
Is the Milky Way Throwing Out Forming Stars?
Some of the scant stars dwelling in the Milky Way's halo may have an unexpected origin: They may come from the galaxy itself.
The Milky Way’s Warped Tutu Twirls Every 600 Million Years
Astronomers have known for decades that our galaxy is warped. Now, they can follow the warp’s rotation as it travels around the galactic center.
Nearby Stellar Nurseries Ride a Giant Wave
Astronomers have found a gigantic, undulating wave of stellar nurseries in our galaxy, just outside the Sun’s orbit in the spiral disk.
Warped Milky Way in 3D
Astronomers have used pulsating stars to trace the crooked shape of our galaxy’s disk.
