Latest Physical cosmology Stories
Researchers have discovered direct, empirical evidence of the existence of gas flows that are consumed by galaxies as fuel.
A cerebral volume that basically presents the analyses of the human scientific knowledge and its significance and contribution to a better understanding of the creation of the universe and life
Astronomers have reportedly discovered the largest known structure in the universe – a formation so massive it would take a vehicle that was moving at light speed roughly four billion light years to cross it.
A popular theory that emphasizes dark energy as a contributor to the acceleration of the universe’s expansion does not fit newly obtained data with regards to one fundamental constant – the proton to electron mass ration – claims a University of Arizona astronomy professor.
Have you ever wished for a time machine to be able to travel to the distant past? What about a "Wayback Television Set" that would allow you to watch an entire month of ancient prehistory in real time?
An astronomer wrote in the journal Physical Review Letters about a new mechanism for the magnetization of the early universe.
The researchers in charge of an award-winning space mission that set out to collect fundamental measurements of the universe have announced they will be releasing their final results after nearly a decade of work.
In 1998 scientists measuring the expansion of the Universe made a startling discovery: the Universe is accelerating. Previously, researchers believed that the expansion of the Universe would eventually slow under the influence of gravity.
Astronomers have discovered seven primitive galaxies that formed more than 13 billion years ago, during the Universe's infancy.
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 Ã— 1015 Mâ˜‰ 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 -04Â° 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...
