Latest Galaxy Stories
Citizen scientists scanning thousands of images from the Spitzer Space Telescope helped NASA scientists discover mysterious objects which have now been identified as a phase of massive star formation, officials at the US space agency announced on Tuesday.
Traveling to planets in a galaxy far, far away – like in the movie Interstellar – may seem like science fiction, but what if the Milky Way was one massive conduit connecting to another far-off point hundreds of light years away?
A massive, high-definition panorama taken by the Hubble Space Telescope is being called the largest picture ever taken, and it shows Andromeda in unprecedented detail, depicting over 100 million individual stars and traversing a 48,000 light-year-long stretch of the galaxy.
In four billion years, a mere blink of an eye by universal standards, planet Earth will be part of a galactic collision when our Milky Way will smash into the Andromeda spiral galaxy. Scientists got a preview of that event earlier this week.
A titanic eruption took that took place at least two million years ago forced gases and other materials outward at speeds of up to two million miles per hour, and astronomers are just now witnessing the aftermath of the explosion thanks to NASA’s Hubble Space Telescope.
Stars reveal how old they are through their spin rate, and just as we humans slow down as we grow older, so do the massive, luminous balls of plasma found in space, according to research published Monday in the journal Nature.
Don’t look now, Milky Way, but it appears that there’s a new dwarf galaxy in the neighborhood.
Some like it hot, but for creating new stars, a cool cosmic environment is ideal. As a new study suggests, a surge of warm gas into a nearby galaxy -- left over from the devouring of a separate galaxy -- has extinguished star formation by agitating the available chilled gas.
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.
Recently, the infrared Herschel Space Observatory, has taken a series of beautiful high-resolution infrared images of Andromeda. It is the first time we can see M31, at these wavelengths, at such a high resolution.
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...
