Latest Big Bang Stories
When astronomers peer into the deepest regions of the cosmos they are not seeing the Universe as it exists today, but rather how it looked billions of years ago.
After four years surveying the Universe for the European Space Agency, the Planck space telescope’s Low Frequency Instrument will be turned off on Saturday.
Astronomers report that they have detected a subtle signal from the Big Bang for the first time, giving a glimpse into the first moments of the Universe.
Scientists have proposed a groundbreaking new theory to explain the discrepancies between different methods for measuring the expansion of the universe.
Physicists have reproduced a pattern resembling the cosmic microwave background radiation in a laboratory simulation of the Big Bang, using ultracold cesium atoms in a vacuum chamber at the University of Chicago.
The best way to solve a mystery, as any detective can tell you, is to revisit the scene where it began and look for clues. Scientists, searching for the mysteries of our universe, are trying to go back as far as they can to the Big Bang.
This spring, scientists from the Max Planck Institute showed humanity the most detailed map ever created of the early universe. The map was generated from data gathered by the Planck spacecraft.

The 2013 Gruber Cosmology Prize recognizes Viatcheslav Mukhanov and Alexei Starobinsky for their formative contributions to inflationary theory, an essential component for understanding the evolution and structure of the universe.
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...
