An international team of astronomers led by Yale University and the University of California-Santa Cruz have pushed back the cosmic frontier of galaxy exploration to a time when the universe was only 5% of its present age.

Astronomers have shown for the first time how star formation in "dead" galaxies sputtered out billions of years ago.

NASA's Hubble Space Telescope has photographed a set of wispy, goblin-green objects that are the ephemeral ghosts of quasars that flickered to life and then faded.

Hubble Views Galaxy NGC 5023 on Edge

This Hubble Space Telescope image shows an edge-on view of the spiral galaxy NGC 5023. Due to its orientation we cannot appreciate its spiral arms, but we can admire the elegant profile of its disk.

A supermassive black hole with a mass four million times that of the Sun lies at the heart of the Milky Way galaxy.

By combining observations from the Japan-led Suzaku X-ray satellite and the European Space Agency's infrared Herschel Space Observatory, scientists have connected a fierce "wind" produced near a galaxy's monster black hole to an outward torrent of cold gas a thousand light-years across.

Like the lost little puppy that wanders too far from home, astronomers have found an unusually small and distant group of stars that seems oddly out of place.

The MUSE instrument on ESO's Very Large Telescope has given astronomers the best ever three-dimensional view of the deep Universe.

NGC 7814 - Little Sombrero

Galaxies can take many shapes and be oriented any way relative to us in the sky.

Galaxies can die early because the gas they need to make new stars is suddenly ejected, research published today suggests.

At a time when our earliest human ancestors had recently mastered walking upright, the heart of our Milky Way galaxy underwent a titanic eruption, driving gases and other material outward at 2 million miles per hour.

Galaxy IC 335 As Seen by Hubble

This new NASA/ESA Hubble Space Telescope image shows the galaxy IC 335 in front of a backdrop of distant galaxies.

The Milky Way's New Neighbor

The Milky Way, the galaxy we live in, is part of a cluster of more than 50 galaxies that make up the 'Local Group', a collection that includes the famous Andromeda galaxy and many other far smaller objects.

For the first time, an international team of astronomers, led by Dr. James Geach from the University of Hertfordshire, has revealed the dramatic 'blow out' phase of galactic evolution.

An Abrasive Galactic Collision

A collision of two galaxies has left a merged star system with an unusual appearance as well as bizarre internal motions.

Using the world's largest radio telescope, two astronomers from Swinburne University of Technology in Australia have detected the faint signal emitted by atomic hydrogen gas in galaxies three billion light years from Earth, breaking the previous record distance by 500 million light years. Their results appear in a paper published in the journal Monthly Notices of the Royal Astronomical Society.

Strange Galaxy Perplexes Astronomers

With the help of citizen scientists, a team of astronomers has found an important new example of a very rare type of galaxy that may yield valuable insight on how galaxies developed in the early universe. The new discovery technique promises to give astronomers many more examples of this important and mysterious type of galaxy.

Youthful Compact Galaxies

Researchers using NASA's Hubble Space Telescope and Chandra X-ray Observatory have uncovered young, massive, compact galaxies whose raucous star-making parties are ending early.

Peering through a giant cosmic magnifying glass, NASA's Hubble Space Telescope has spotted a tiny, faint galaxy -- one of the farthest galaxies ever seen. The diminutive object is estimated to be more than 13 billion light-years away.

A Young Galaxy in the Local Universe?

Astronomers usually have to peer very far into the distance to see back in time and view the universe as it was when it was young.
