An international team of researchers working at the W. M. Keck Observatory in Hawaii have reportedly discovered a new type of galaxy which theoretically should not be able to exist: one that is nearly as wide as the Milky Way but contains just one percent as many stars.

At first glance, there is not the slightest doubt: to us, the universe looks three dimensional. But one of the most fruitful theories of theoretical physics in the last two decades is challenging this assumption. The "holographic principle" asserts that a mathematical description of the universe actually requires one fewer dimension than it seems. What we perceive as three dimensional may just be the image of two dimensional processes on a huge cosmic horizon.

“Dark energy” used to only be a buzzword used by psychics. Now, though, it's picking up steam in physics, too.

About 1/4 of the universe is composed of dark matter, so it’s kind of a big deal. But do you know what it is?

By observing colliding galaxies with the ESO’s Very Large Telescope (VLT) and the Hubble Space Telescope, astronomers have found evidence suggesting for the first time that dark matter may interact with other dark matter in a way other than through gravity.

Chuck Bednar for redOrbit.com - @BednarChuck After two years worth of work by some 300 researchers, the Dark Energy Survey (DES) project have unveiled the first in a series of dark matter maps showing the distribution of the mysterious substance experts believe makes up roughly 27 percent of the universe. According to BBC News, the maps show how conglomerations of dark matter change over time and was created using a 570-megapixel camera attached to the Victor Blanco telescope in Chile....

Astronomers found that the type of supernovae commonly used to measure distances in the universe fall into distinct populations not recognized before, and this questions how fast the universe has been expanding.

A new survey by the NASA/ESA Hubble Space Telescope and NASA’s Chandra X-ray Observatory studied 72 galactic cluster collisions from all different angles and times, revealing that the 85 percent of the universe’s total matter is way weirder than we could ever imagine.

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 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...

As of 2009, JKCS 041 is a group of galaxies with the distinction of being the farthest away group from Earth ever observed. Seen at redshift 1.9, it is estimated to be 10.2 billion light years away. The cluster is located within the constellation Cetus at a photometrically determined redshift of z=1.9 at right ascension 2h 26m 44s declination -04° 41"² 37"³ (J2000.0).

Sample Entry: Astronomy is the scientific study of stars, planets, comets, galaxies, and other phenomena that occur outside Earth's atmosphere (e.g. cosmic radiation). Astronomy deals with the evolution, physics, chemical makeup, meteorology, and motion of celestial objects, and also the formation of the universe. The word Astronomy comes from the Greek words astron (meaning "star") and nomos (meaning "law"). Astronomy is one of the oldest sciences. Since the dawn of man, people always...
