Someone dimmed the lights in space. Scientists observe a dimming quasar for the first time ever, and this could lead to a understanding of the mysterious black holes and their lifespans.
Company receives 'Big Data Competency' status and introduces enhanced solution for Amazon Redshift at AWS re:Invent in Las Vegas BURLINGTON, Massachusetts, November 11, 2014 /PRNewswire/ --
Pamela Fleming, Executive Vice President, The Institute for Basic Research, Florida, announces that "The recently observed 'Red Moon' establishes the lack of expansion of the universe
New program to further ease onboarding and provide express data loading to the cloud BURLINGTON, Massachusetts, July 22, 2014 /PRNewswire/ -- Attunity Ltd.
Two recent studies of the early Universe using the Baryon Oscillation Spectroscopic Survey (BOSS), a component of the third Sloan Digital Sky Survey (SDSS-III), have made the most accurate measurement of the rate of expansion in the early Universe to date.
RedShift reaches a key milestone in the development of its next generation of broadly tunable mid-IR lasers. Burlington, MA (PRWEB) January 22, 2014
Researchers from the Baryon Oscillation Spectroscopic Survey (BOSS) announced on Wednesday that their project has measured the scale of the universe to an accuracy of one percent.
Dundas Data Visualization is now able to provide data visualization solutions for analyzing and presenting big data on Amazon Redshift. Toronto, Ontario (PRWEB)
According to Hubble’s law, the frequency of light from distant galaxies is shifted toward the red in a way proportional to their distance D, z = HD, where H is Hubble's constant. Dr. J.
In a recent NPR interview, astronaut Chris Hadfield indicated that his spaceship became "blood red" when seeing Sunrise, thus confirming that Sunlight passing through our atmosphere
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).
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...
