Black Holes

Dust in the Heart of Circinus

Infrared observations of the Circinus Galaxy may help reveal the shape of the dusty region fueling its active galactic nucleus and shed light on what governs dust structures in other galaxies.

Dark Matter Spotted in the Milky Way?

A team of astronomers claim to have the most compelling case for annihilating dark matter yet.

Direct Evidence of Big Bang Inflation

Researchers with an experiment based at the South Pole have discovered the long-sought "smoking gun" for inflation. The signal was hidden in polarization patterns in the cosmic microwave background and confirms physicists' audacious theory of how the Big Bang happened.

"Proof of Inflationary Universe" to be Announced

Rumors are flying that the long-sought "smoking gun" for inflation has been found in polarization patterns in the cosmic microwave background. If so, it would confirm the inflation theory for how and why the Big Bang happened.

Hubble Displays Galactic Jellyfish

These stunning new images of spiral galaxy ESO 137-001 highlight its violent encounter with the intracluster plasma of Abell 3627, which is stripping away its gas and forming stars in the streamers.

Rocky Encounter with Stellar Lighthouse

Asteroid debris might be bombarding a radio pulsar in the constellation Puppis.

Mystery of the Missing Galaxy Clusters

Astronomers have counted up the number of galaxy clusters in the cosmos and found a problem: the number is much lower than they expected. What's going on?

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.

Galactic Runts Carry Beefy Black Holes

Astronomers have found supermassive black holes in 151 dwarf galaxies, surprising expectations and providing a time machine into black hole formation.

Gaia Launches to Pinpoint a Billion Stars

Gaia launched flawlessly Thursday morning at 9:12 UTC (4:12 a.m. Eastern Standard Time). This long-awaited mission will precisely map the distances and motions of 1 billion stars in our galaxy.

A Double Black Hole?

Strange emission from a distant galaxy paints an enigmatic picture of what’s happening inside its core. One solution: instead of one supermassive black hole, the galaxy hosts two trapped in a tight dance around each other.

Triple Collision in Infant Galaxy

A complex of three bright, star-forming clumps called Himiko is merging in the early universe. With its light reaching us from when the universe was only 800 million years old, this primordial galaxy could yield insight into the elusive process of early galaxy formation.

A Galaxy Near Cosmic Dawn

Astronomers have confirmed that light from a distant galaxy is reaching us from about 700 million years after the Big Bang. The galaxy's emission hints that star formation during that era might have proceeded at a much faster rate than previously thought.

Milky Way

Source Found for Magellanic Stream

New observations solve the origins of a long rivulet of gas encircling the Milky Way.

"Smoking Gun" from Galactic Smashup?

Observations from the Chandra X-ray Observatory suggest that something has slammed into the spiral galaxy NGC 1232. But you'd never know it from the galaxy's unperturbed appearance

Cat’s Paw Nebula: Nearby Mini-Starburst?

The Cat's Paw Nebula is home to many bright, young stars. But thousands of fainter stars concealed behind dust reveal themselves in a new infrared image.

New View of Nearest Galaxies

Spectacular high-resolution images released at the 222nd American Astronomical Society conference in Indianapolis reveal two of the Milky Way’s nearest galactic neighbors in a new light.

The Mysterious Seven

Seven clouds of hydrogen dotting the space between two iconic galaxies might be crumbs from a past encounter or evidence for the elusive cosmic web theorized to fuel galaxy growth.

How to Build a Galaxy

The iconic disk galaxy is perhaps the most common type of galaxy in the universe. But how did these galaxies form their wide, thin skirts and fat, round centers?

Stellar Science

The Most Distant Star Ever Seen?

Astronomers have detected what might be the farthest star ever spectroscopically observed. The bright object blazes in an unusual location, too, perhaps giving insight into star formation in unconventional environments.
