Latest Galaxy Stories
Stretching almost halfway around the Milky Way galaxy, the Magellanic Stream is a ribbon of gas that has puzzled astronomers for decades. Now, using data from the Hubble Space Telescope (HST), astronomers now believe that they have nailed down its source.
An international team led by astronomers from Kyoto University, the University of Tokyo and the University of Oxford has released its first version of a 3D map of the Universe from its FastSound project
In the hunt for dark matter and dark energy, researchers now have a new weapon in their arsenal: the Hyper-Suprime Cam (HSC).
Thanks to new data obtained from the Hubble Cosmological Evolution Survey, researchers have solved the mystery as to why some galaxies appear to grow larger even after they no longer form new stars.
Understanding how the Milky Way formed is one of the central scientific questions in astronomy. Yet given the scale and complexity of the galaxy, there is a lot to consider.
Astronomers have been observing the Whirlpool Galaxy since the 18th century, but they’ve never seen it like this.
Astrophysicists writing in The Astrophysical Journal have shed some new light on the universe's brightest objects - quasars.
Astronomers using NASA's Hubble Space Telescope are tracking the orbital motion of 33,000 stars in one of the Milky Way's oldest globular clusters.
“How to Understand the True Cosmos” aims to dispel misconceptions in astrophysics. Massachusetts (PRWEB) July 19, 2013 The rapid pace of scientific
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...
