Hubble Telescope Captures Two Colliding Galaxies Conducting Deadly Dance

The Hubble Space Telescope has captured a new, spectacular image of two galaxies colliding. The interacting galaxies, known as Arp 142, are currently conducting a dance that will either lead to their eventual merge--or their mutual destruction.

Smallest Galaxy in Known Universe Measured: Tiny System Discovered by Astronomers

You normally wouldn't consider a galaxy to be "tiny;" but in this case, it is. Astronomers have now measured the least massive galaxy in the known universe, and have made some surprising discoveries because of it.

Milky Way Galaxy's Local Arm Far Larger Than Previously Thought

Astronomers once thought that our Solar System's Milky Way galaxy resided in a small structure called the Local Arm. Now, though, they've discovered that the Local Arm is far larger than previously thought and is more like the adjacent major arms rather than a small spur.

How Galaxies Feed: Cosmic Swirly Straws Suck up Funnels of Fuel

Galaxies form over billions of years, using cosmic material to form planetary bodies. Now, researchers have discovered how these galaxies actually feed; they may employ a cosmic version of swirly straws.

Rare Merger of Ancient Galaxies Solves Mystery of Galaxy Evolution

Years ago when the universe was still young, two massive galaxies collided. Now, ESA's Herschel space observatory has spotted the rare encounter between the two gas-rich galaxies, which may provide clues to galaxy formation.

Enormous Galaxy Cluster Seen Distorting Space-Time Fabric

Bright arcs can be seen smeared around the heart of the enormous galaxy cluster Abell S1077 in this image taken by the Hubble space telescope. These arcs are actually stretched images of distant galaxies distorted by the cluster's huge gravitational field.

Enormous Cloud Around Two Colliding Galaxies Imaged by Chandra X-Ray Observatory

A new image of the space-based X-ray observatory Chandra shows the enormous cloud of hot gas resulting from the epic collision of two large, colliding galaxies. This unusually large reservoir of gas contains as much mass as 10 billion Suns, spans about 300,000 light years, and radiates at a temperat...

Our Galaxy is Ancient, But New Stars Are Still Born (Picture)

Our galaxy is nearly as old as the Universe itself, but there is still some action in the form of newborn stars. The age of the Universe can be determined quite exactly to be 13.8 billion years, while our galaxy, the Milky Way, is also ancient — some of its stars are more than 13 billion years old...

The Lost Galaxy NGC 4535 Seen Through ESO Very Large Telescope

The ESO 8.2-meter Very Large Telescope made this amazing image of "the lost galaxy" NGC 4535, which is one of the largest galaxies in the massive Virgo Cluster. This mega cluster consists of as many as 2000 galaxies and is about 50 million light-years away. Although the Virgo Cluster is not much lar...

Whirlpool Galaxy M51 is a Real Beauty

The Whirlpool Galaxyis one of astronomy's galactic darlings. Located only about 30 million light-years away in the constellation Canes Venatici (the Hunting Dogs), the Whirlpool's beautiful face-on view and closeness to Earth allow astronomers to study a classic spiral galaxy's structure and star-fo...
