Why Do Quenched Galaxies Seem To Keep Growing?
2013-08-02 04:02:20

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.

Google Hangout: A New Baby Picture Of The Universe

This spring, scientists from the Max Planck Institute showed humanity the most detailed map ever created of the early universe. The map was generated from data gathered by the Planck spacecraft.

Mystery Missing Massive Galaxies

New observations have given a group of astronomers the best view yet of how star formation regions can get selfish and gassy.

Astronomers Catch Distant Galaxy Snacking On Gas
2013-07-04 13:01:16

Astronomers were able to catch a distant galaxy in the act of snacking on nearby gas while using the European Space Observatory's Very Large Telescope.

Hubble And VLT Data Reveals Details Of An Early Galaxy
2013-07-03 04:39:20

Researchers have published details, including size, mass and content of elements, of an early galaxy in the scientific journal Monthly Notices of the Royal Astronomical Society.

Spiral Galaxies Larger Than Thought

Astronomers now say spiral galaxies like the Milky Way galaxy are actually larger than previously thought.

New Hubble Image Shows Interacting Galaxies
2013-06-20 18:59:33

New images taken by the Hubble Space Telescope of a pair of galaxies experiencing a close encounter have been released.

Astronomers Observe Galaxy In Act Of Dying
2013-06-03 13:16:28

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.

Cold Gas May Fuel Galaxy And Star Formation
2013-05-26 05:49:55

As galaxies grow over the course of billions of years, they apparently use the cosmic equivalent of bendy straws to feed on cold gas and gain mass, according to new research published in the May 20 edition of the Astrophysical Journal.

Galaxy Mega Merger Spotted By Herschel And Keck
2013-05-23 04:53:50

Around 11 billion years ago, two hungry young galaxies collided and they are now forming a massive galaxy approximately 10 times the size of the Milky Way. The new mega-galaxy, HXMM01, was discovered as part of a UC-Irvine led project conducted with the W.M. Keck Observatory, the Herschel space observatory, and other research facilities around the world.

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...

The Abell 520 galaxy cluster is an strange structure formed by a major merger. Due to its odd and chaotic nature it has been given the nick-name the Train Wreck Cluster. The Dark Matter within the cluster does not act as expected like it does in other clusters, therefore, Abell 520 creates problems for many of the prevailing theories about Dark Matter. It also disrupts many alternative theories of modified gravity. Similar to the Bullet Cluster the gas contents and galaxies within the...

Ring Galaxy -- A subclass of interacting galaxies, ring galaxies, provides a unique laboratory for studying unusually large bursts of non-nuclear star formation. The rings in these systems are often large (10s of kiloparsecs) and contain what appear to be associations of giant H{\small II} regions. As a basis for future modeling of star forming regions in observed ring galaxies we present a series of combined n-body/gas numerical experiments on ring formation and evolution. Three...

Molecular Cloud -- Molecular clouds are interstellar nebulae that have a density and size sufficient to permit the formation of H2, molecular hydrogen. However, this molecule is difficult to detect, and the molecule most used to trace the H2 is CO (carbon monoxide). The ratio between CO luminosity and H2 mass is roughly constant, although there are reasons to doubt this assumption in observations of some other galaxies. In the Milky Way, molecular clouds account for roughly one-half...

Globular Cluster -- A globular cluster is a cluster of stars that is spherical in shape and extremely dense towards its core. Globular clusters are usually composed of hundreds of thousands of old stars, similar to the bulge of a spiral galaxy but confined to a volume of only a few cubic parsecs. Some globular clusters (like Omega Centauri in our Milky Way, and G1 in M31) are truly massive clusters, with several million times the mass of our Sun. Such globular clusters may be the...
