Latest Big Bang Stories
Led by Berkeley Lab scientists, the Sloan Digital Sky Survey’s BOSS is bigger than all other spectroscopic surveys combined for measuring the universe's large-scale structure
Stanford physics Professor Andrei Linde has been named an inaugural winner of the $3 million Fundamental Physics Prize.
Dark energy makes up about 70 percent of the current content of the Universe and thus holds the ultimate fate of our Universe.
Astronomers have puzzled over why some puny, extremely faint dwarf galaxies spotted in our Milky Way galaxy's back yard contain so few stars.
Dark galaxies are small, gas-rich galaxies in the early Universe that are very inefficient at forming stars.
University of Texas astronomers use Lonestar supercomputer to explore role of dark matter in galaxy formation
Researchers from Europe and Japan have discovered a submillimeter galaxy -- a type of galaxy that has intense star formation activity and is covered by large amounts of dust -- located approximately 12.4 billion light-years away.
Charles L. Bennett and the Wilkinson Microwave Anisotropy Probe (WMAP) team are the recipients of the 2012 Gruber Cosmology Prize.
Theories of the primordial Universe predict the existence of knots in the fabric of space - known as cosmic textures - which could be identified by looking at light from the cosmic microwave background (CMB), the relic radiation left over from the Big Bang.
More atomic hydrogen gas — the ultimate fuel for stars — is lurking in today’s Universe than we thought, CSIRO astronomer Dr Robert Braun has found.
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.

Large-Scale Structure of the Cosmos -- Stars are organised into galaxies which in turn appear to form clusters and superclusters, separated by voids. Prior to 1989 it was commonly assumed that the superclusters were the largest structures in existence, and that they were distributed more-or-less uniformly throughout the universe in every direction. However, in 1989, Margaret Geller and John Huchra discovered the "Great Wall", a sheet of galaxies more than 500 million light years long...
Cosmology -- area of science that aims at a comprehensive theory of the structure and evolution of the entire physical universe. Modern Cosmological Theories Present models of the universe hold two fundamental premises: the cosmological principle and the dominant role of gravitation. Derived by Hubble, the cosmological principle holds that if a large enough sample of galaxies is considered, the universe looks the same from all positions and in all directions in space. The second point...
Redshift -- Redshift is the phenomenon that the frequency of light when observed, under certain circumstances, can be lower than the frequency of light when it was emitted at the source. This usually occurs when the source moves away from the observer, as in the Doppler effect. More specifically, the term redshift is used for the observation that the spectrum of light emitted by distant galaxies is shifted to lower frequencies (towards the red end of the spectrum, hence the name) when...
Quasar -- A quasar (from quasi-stellar radio source) is an astronomical object that looks like a star in optical telescopes (i.e. it is a point source), but has a very high redshift. The general consensus is that this high redshift is cosmological, the result of Hubble's law and that their redshift indicates that they are typically very distant from Earth; we observe them as they were several billions of years ago. Since we can see them despite their distance, they must emit more...
