Astronomers Observe Galaxy In Act Of Dying

Astronomers announced at the 222nd American Astronomical Society meeting in Indianapolis that they have observed the first clear example of a galaxy in the act of dying.

Halo Clouds Spotted Around Colliding Galaxies

A detailed study of an enormous cloud of hot gas that envelops two large, colliding galaxies has been made using NASA’s Chandra X-ray Observatory. This oversized gas reservoir contains as much mass as 10 billion Suns, is 300,000 light years across, and radiates more than 7 million degrees Kelvin.

Astronomers Rethink Black Hole Growth Rate

New research published in the Astrophysical Journal suggests black holes are growing at larger rates than what had previously been thought possible.

Hubble Image Shows Hercules A

A new Hubble Space Telescope image released today shows off a multi-wavelength view of radio galaxy Hercules A.

Hubble Tuning Fork Interactive Diagram

The European Space Agency released an image this week of an interactive diagram known as the Hubble Tuning Fork which helps to describe the shape of galaxies, which can come in all different sizes.

Monster Galaxy Found

A team of astronomers has grabbed an image of a huge elliptical galaxy with a core that is bigger than any seen before.

Astronomers Discover Elliptical Galaxy With Split Personality
2012-10-22 14:25:03

While most elliptical galaxies are considered vintage, retired star making neighborhoods, astronomers have found one that has a personality more like that of a pinwheel-shaped spiral galaxy.

Galactic Collisions Between Big Galaxies Form Even Bigger Galaxies
2012-10-12 14:36:09

When massive galaxies belly-up to the interstellar buffet, their centers expand as they gobble up other galaxies that contain billions and billions of stars, according to a new report from University of Utah astronomers.

Galaxy Pair Imaged By Hubble
2012-09-06 08:18:33

The Hubble Space Telescope has taken a portrait of two different galaxies forming a peculiar galaxy pair called Arp 116. The image released today shows the dramatic differences in size, structure and color between spiral and elliptical 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 Coma Cluster (Abell 1656), along with the Leo Cluster, is one of two major clusters compromising the Coma Supercluster. It contains over 1000 identified galaxies. Most of the galaxies in the center of the Coma Cluster are elliptical galaxies including both dwarf and giant. However the center is dominated by NGC 4874 and NGC 4889, two giant elliptical galaxies. The brightest galaxies are visible, a few degrees north of the galactic pole, with an amateur telescope larger than 20 cm. The...

Spiral Galaxy -- Among the galaxies, there are apparently three main categories, according to their appearance: the disk galaxies (`cosmic frisbies' according to P. Murdin, D. Allen, and D. Malin), consisting of a huge disk of stars and interstellar matter, which may form interesting patterns, the elliptical galaxies (`cosmic footballs') which are uniformly looking, ellipsoidal agglomerations of stars, and the irregular galaxies (`cosmic misfits') which cannot be integrated in this scheme....

Elliptical Galaxy -- In astronomy, one of the main classes of galaxy in the Hubble classification and characterized by a featureless elliptical profile. Unlike spiral galaxies, elliptical galaxies have very little gas or dust and no stars have recently formed within them. They range greatly in size from giant ellipticals, which are often found at the centres of clusters of galaxies and may be strong radio sources, to tiny dwarf ellipticals, containing about a million stars, which are...

Seyfert's Sextet -- Seyfert's Sextet is a group of galaxies in which gravitational forces are exerted between its members. The galaxies are so tightly packed together that gravitational forces are beginning to rip stars from them and distort their shapes. Those same gravitational forces eventually could bring the galaxies together to form one large galaxy. The name of this grouping, Seyfert's Sextet, implies that six galaxies are participating in the action. But only four galaxies are...
