For decades, the mystery of Dark Matter has been at the forefront of physics research. Since the 1930s, scientists have been aware that all of the mass that we can see – the stars, the dust, the planets, and black holes – makes up only 20 percent of the Universe.

According to astrophysicists, dark matter is the key to understanding the universe as it comprises 85 percent of all mass found in it and is suspected to have caused the growth of galaxies.

Clumped Galaxies Give General Relativity Its Toughest Test Yet

Many of the oldest and most massive galaxies reside together in enormous structures known as clusters, and now a team of astronomers has confirmed the existence of an unusually distant galaxy cluster.

Testing Einstein's Theory Of Relativity Through Cosmic Microwave Measurements

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...
