Astronomers have found that dark matter does not slow down when colliding with itself, meaning it interacts with itself less than previously thought, narrowing down what this crazy substance might be.
WASHINGTON, March 26, 2015 /PRNewswire-USNewswire/ -- Using observations from NASA's Hubble Space Telescope and Chandra X-ray Observatory, astronomers have found that dark matter does not slow
A mysterious explosion in the sky observed in the 17th century was not a nova, but a much rarer, violent stellar collision.
Astronomers have identified a previously invisible stellar cluster currently forming over 1 million new stars, according to a report in the journal Nature.
Hi neighbors! Astronomers have discovered a 'treasure trove' of 9 previously undetected dwarf satellites (including 3 small galaxies) orbiting around the Milky Way.
A dwarf galaxy recently discovered orbiting the Milky Way appears to be radiating gamma rays, and leading researchers from Brown and Carnegie Mellon universities hypothesize that it could be filled with particles of the mysterious substance known as dark matter.
PITTSBURGH, March 10, 2015 /PRNewswire-USNewswire/ -- A newly discovered dwarf galaxy orbiting our own Milky Way has offered up a surprise -- it appears to be radiating gamma rays, according
Some of the galaxies in our universe are veritable star nurseries. For example, our own Milky Way produces, on average, at least one new star every year. Others went barren years ago, now producing few if any new stars. But why?
Dust plays an extremely important role in the universe - both in the formation of planets and new stars. But dust was not there from the beginning and the earliest galaxies had no dust, only gas. Now an international team of astronomers, led by researchers from the Niels Bohr Institute, has discovered a dust-filled galaxy from the very early universe. The discovery demonstrates that galaxies were very quickly enriched with dust particles containing elements such as carbon and oxygen, which...
A team of Brazilian astronomers were surprised when they investigated a seemingly empty spot in the Milky Way and found a stellar nursery containing 2 clusters of stars.
Image Caption: The Hubble Extreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed by humans. Each speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is estimated to contain more than 200 billion galaxies.

The Virgo Cluster consists of galaxies at a distance of around 59 Mly away in the constellation Virgo. Containing between 1300 to 2000 galaxies the Virgo Cluster is the heart of the Local Supercluster. Its mass is estimated at 1.2 Ã— 1015 Mâ˜‰ out to 8 degrees of the cluster's center or a radius of about 2.2 Mpc. Most of the brighter galaxies in the cluster were discovered by Charles Messier in the late 1770's and early 1780's, including the giant elliptical Messier 87. Messier...
The two Magellanic Clouds (or Nubeculae Magellani), composed of the Large Megellanic Cloud and the Small Magellanic Cloud, are irregular dwarf galaxies visible in the southern hemisphere. They are members of our Local Group and orbit the Milky Way galaxy. Persian astronomer Al Sufi, in 964, was the first to have written anything about the Magellanic Clouds proving they have been known since early time amongst the Middle East peoples. Sufi, in his Book of Fixed Stars, calls the clouds...
The M96 Group (also known as the Leo I Group), one of many in the Virgo Supercluster, is located within the Leo constellation and contains between 8 and 24 galaxies, including three Messier objects. The Leo Triplet, which is physically near M96 Group, and M96 may actually be separate parts of a much larger group.
The M81 Group, containing the well known galaxies Messier 81 and Messier 82, is a group of galaxies within the constellation Ursa Major. Along with Messier 81 and 82 are several other galaxies with apparent brightness. The center, located at an approximate distance of 3.6 Mpc, is one of the nearest groups to the Local Group. The total estimated mass of the group is (1.03 Â± 0.17) Ã— 1012Mâ˜‰. The Virgo Supercluster contains the M81 Group, the Local Group, and some other nearby...
