Latest Physical cosmology Stories
Scientific studies done with the "PAPER" array, one of the world-class scientific instruments in South Africa's Karoo Radio Astronomy Reserve, is producing ground-breaking science and spectacular cosmic images, resulting in several important articles in top astronomy journals.
Del Monte Gives His Perspective of M-Theory and Its Importance to Science Minneapolis, Minnesota (PRWEB) May 09, 2013 Author, physicist and CEO, Louis
A team of international scientists has found the first ever direct evidence of pear-shaped atomic nuclei, a discovery that could shed light on some of the deepest mysteries of the universe.
Using the NSF's Green Bank Telescope, astronomers have discovered large clouds of hydrogen lurking in our galactic neighborhood.
Scientists have debated the merits of the anthropic principle – the notion that the universe is somehow fine-tuned for life, or vice versa – and its variants for decades. The search to understand the nature and evolution of the universe is what plagues the fields of cosmology and astrophysics.
In 2011, the Nobel Prize for Physics was awarded to a trio of researchers. Adam Riess, Saul Perlmutter and Brian Schmidt were able to determine that the speed and scope of the expansion of the universe is not so uniform as once believed.
A team of physicists has made new observations of the blazar known as PKS 1424+240 that reveal it is the most distant known source of very high-energy gamma rays.
Although he probably never expected a career in physics would warrant it, Stephen Hawking received a ‘rock star’ reception to his speaking engagement at the California Institute of Technology (Caltech) in Pasadena, California on Tuesday.
Astronomers say they have discovered a star factory in a galaxy so distant that they see it when the Universe was only six percent of its current age of about 13.7 billion years old.
"If the Universe started with a bang, and no one was alive yet to observe it, would it still make a sound?" It sounds like the start of a really cliché joke, but the answer, surprisingly, is yes.
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...
