Latest Physical cosmology Stories
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.
Louis Del Monte’s webisodes aim to address scientifically how the universe will end. Minneapolis, Minnesota (PRWEB) June 04, 2013 In his newest two-part
Approximately 80 percent of all unidentifiable millimeter wave signals emitted in the universe actually originate from galaxies, according to new research published in Saturday’s edition of the Astrophysical Journal Letters.
Scientists working with the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered the most distant and active star forming galaxies in our universe.
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.
Measuring the number and energy of each particle of light or photon since the Big Bang could provide secrets about the nature and evolution of the Universe, such as how similar or different ancient galaxies were compared to the galaxies today.
Scientists have finally resolved the mystery over the distance and measured brightness of a nearby star system known as SS Cygni.
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...
