One of the greatest aspects of NASA’s astronomical research program is that the data accumulated from virtually all of the instruments – X-ray satellites, Infrared detectors, gamma-ray satellites – is available to the public.

Gamma ray burst buried in dust

For the first time ever, scientists using the Atacama Large Millimeter/submillimeter Array have discovered molecular gas in galaxies that had once been rocked by gamma ray bursts, according to new research published Wednesday in the journal Nature.

Neighboring Satellite Dwarf Galaxies Do Not Fit The Standard Model

Smith Cloud Survives Galactic Collision Thanks To Full Dark-matter Facket

Like a bullet wrapped in a full metal jacket, a high-velocity hydrogen cloud hurtling toward the Milky Way appears to be encased in a shell of dark matter. stronomers believe that without this protective shell, the high-velocity cloud (HVC) known as the Smith Cloud would have disintegrated long ago when it first collided with the disk of our Galaxy.

Cosmic Clumps Cast Darkest Shadows Ever Recorded

Astronomers have found cosmic clumps so dark, dense and dusty that they throw the deepest shadows ever recorded.

In the normal course of evolution, galaxies initially formed stars as clouds of hydrogen and helium collapsed. Eventually the density and temperature of the cores would ignite nuclear fusion, allowing them to shine during what we call the main sequence phase of their lives.

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 × 1015 M☉ 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 ± 0.17) × 1012M☉. The Virgo Supercluster contains the M81 Group, the Local Group, and some other nearby...
