Data Supports Cold Model Dark Matter

Researchers found that the density of the dark matter was greater near the center of the galaxy clusters, on average, gradually becoming more diffuse moving out towards the cluster’s edge. This is consistent with a cold dark matter model, which, along with other evidence, has been the leading candidate theory for some years.

How Does Hydrogen Drive Star Formation In Galaxies

A major field of study in astronomy seeks to understand how galaxies form and evolve. One advantage that we possess is that as we study the light from the most distant galaxies, we are effectively looking back in time, seeing the oldest galaxies in the Universe when they were still young.

Euclid Dark Matter Mission Now In Development
2013-06-11 13:13:58

The European Space Agency's Euclid module under development in France will be helping to explore dark energy and dark matter in the universe.

Dark Matter Not Actually Dark
2013-06-11 09:51:15

New research is building upon the notion that dark matter may be Majorana particles, and suggests that perhaps dark matter can interact electromagnetically after all – meaning that dark matter may not be ‘dark’ after all.

Astronomers Size Up The Smallest Galaxy In The Universe

University of California, Irvine scientists reported on Monday that they have measured the least massive galaxy in the known universe.

Black Holes Abundant Early Universe
2013-06-06 14:16:28

New data from NASA’s Chandra X-ray Observatory and NASA’s infrared Spitzer Space Telescope, has revealed that the early Universe may have contained more black holes than previously expected.

The big bang theory is the leading theory to explain the origin of the Universe. But this does not mean that the big bang is without its problems.

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...
