2014-01-17 11:14:32

redOrbit Staff & Wire Reports - Your Universe Online Scientists from the California Institute of Technology (Caltech) and NASA’s Jet Propulsion Laboratory (JPL) report in a recent study that they have observed a change in an individual object’s cosmic microwave background radiation resulting from its interaction with massive moving objects for the first time ever. According to the recently-published paper in The Astrophysical Journal, this phenomenon, which is known as the...

Himiko Galaxy's 'Space Blob' Halo Dates Back To The Cosmic Dawn
2014-01-17 08:10:48

redOrbit Staff & Wire Reports - Your Universe Online Questions surrounding the glowing gaseous halo extending from a massive early galaxy that have puzzled astronomers since its discovery in 2009 have finally been answered by research appearing in a recent edition of The Astrophysical Journal. Himiko, a very large and extremely distant galaxy with a gaseous halo extending over 55,000 light years, was first discovered four years ago using the Subaru Telescope located at Hawaii’s...

redOrbit Staff & Wire Reports - Your Universe Online Using the Hubble Space Telescope, a team of researchers has discovered the smallest, faintest and most numerous galaxies ever discovered in the remote universe, according to research presented Tuesday at the annual meeting of the American Astronomical Society (AAS) in Washington DC. The University of California, Riverside-led team – whose research will also appear in the January 10 issue of The Astrophysical Journal – used...

The historical, theoretical and experimental evidence on the lack of expansion of the universe was confirmed at five scientific meetings in Europe and in the Far East (http://www.santilli-foundation.org/Conf-2013-No-Univ-Exp.php). Palm Harbor, Florida (PRWEB) December 20, 2013 The historical, theoretical and experimental evidence on the lack of expansion of the universe was confirmed at five scientific meetings in Europe and in the Far East...

Urban Galactic Clusters Stopped Forming Stars Billions Of Years Ago
2013-12-19 12:36:09

Brett Smith for redOrbit.com - Your Universe Online A new study based on data from NASA’s Spitzer Space Telescope has revealed new details about so-called urban galaxies that exist in large clusters. The study found that these clusters stopped forming new stars about 9 billion years ago, much later than previously thought. These galactic cities were said to have eventually either used up or lost their fuel. Meanwhile, more rural galaxies are still actively forming stars. "We know...

Brett Smith for redOrbit.com - Your Universe Online Based on observations from the South Pole Telescope, a team of international scientists has found subtle patterns in the cosmic microwave background called B-mode polarizations, according to a report in Physical Review Letters. “The detection of B-mode polarization by South Pole Telescope is a major milestone, a technical achievement that indicates exciting physics to come,” said study author John Carlstrom, a deputy director of...

John P. Millis, PhD for redOrbit.com - Your Universe Online For several decades now the leading model for the origin and evolution of the known Universe is a concept known as the Big Bang. Nearly 15 billion years ago, quantum fluctuations of the infinite vacuum of space-time caused the emergence of a rapidly expanding Universe, ultimately filled with matter and radiation. But what initially caused the fluctuation? According to quantum mechanics, it is a natural result of the...

Three Primordial Galaxies Found Merging Near ‘Cosmic Dawn’
2013-11-21 13:36:25

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have found a group of primitive galaxies 13 billion light-years away sitting inside a blob of gas. A team using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope and NASA’s Hubble Space Telescope discovered three infant galaxies merging inside a giant bubble of hot ionized gas. The object, known as Himiko, is 10 times larger than typical galaxies discovered from this era and is comparable in size to our...

Study Uses Big Bang Afterglow To Show Earth Has No Special Place In Expanding Universe
2013-11-07 07:53:48

Dartmouth College In a new study, Dartmouth researchers rule out a controversial theory that the accelerating expansion of the universe is an illusion. While the findings don't explain the cosmic speed-up, they eliminate one provocative possibility that our planet, solar system and galaxy are at the center of the universe and that there is no dark energy. The findings appear in the journal Physical Review D. The 2011 Nobel Prize was awarded for the discovery that the expansion of the...

Astronomers Discover The Most Distant Galaxy Yet In The Universe
2013-10-23 16:48:14

Lawrence LeBlond for redOrbit.com - Your Universe Online A team of Texas and California scientists have discovered the most distant galaxy to date, after searching through a database of nearly 100,000 galaxies imaged by the Hubble Space Telescope as part of the CANDELS survey. Bahram Mobasher and Naveen Reddy of University of California, were part of the team who discovered this distant galaxy. They collaborated on the project with researchers from Texas A&M University, the...

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...
