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

Milky Way

Mapping the Outer Milky Way

Stars still embedded in their natal clouds act as signposts to map the Sagittarius-Carina, Perseus, and Outer spiral arms of the Milky Way.

High-energy X-rays in Milky Way's center

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.

New Stars On Strange Orbits in Milky Way

Astronomers have found two just-born star clusters an incredible 16,000 light-years above the plane of the Milky Way galaxy.

New Stars in the Shadow of a Black Hole

New observations suggest that several dozen low-mass stars, and eventually perhaps even planets, are forming just 2 light-years from our galaxy’s supermassive black hole.

Cepheids Map Milky Way - and Beyond

Cepheid variable stars are helping astronomers see what our galaxy looks like from within.

Yellowballs: A New View of Star Formation

Thanks to the help of the general public, astronomers have discovered a new signature marking a hidden phase of star formation.

Black Holes

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.

Planck map with cosmic infrared background


Big Bang Inflation Evidence Inconclusive

New analyses suggest that observations heralded as evidence for the universe’s brief growth spurt don’t conclusively show what researchers thought they did.

Milky Way's magnetic field


Planck's Magnetic Map of Our Galaxy

The ESA's Planck mission has released one of the most detailed maps of the Milky Way's magnetic field.

Milky Way

Young Stars Lead the Magellanic Stream

Astronomers have discovered hot, young stars in the Leading Arm of the Magellanic Stream, calling the history of the Magellanic Clouds once again into question.

Milky Way

Fingerprinting the Circumgalactic Medium

A new study finds the space surrounding dwarf galaxies in the nearby universe to be shockingly pristine.


Galaxies Grow By Snacking

Evidence from observations and computer simulations supports a picture of galaxy growth that isn't dominated by the rough-and-tumble crashes of big galaxies. Instead, most of the universe's stellar metropolises appear to feed themselves with nibbles instead of feasts.

Milky Way

Mapping the Milky Way's Arms

Astronomers continue to debate whether our home galaxy has big arms and some smaller appendages — or, as new results suggest, four major arms.
