Big Bang May Have Actually Been A Big Freeze
2012-08-21 05:03:30

April Flowers for redOrbit.com - Your Universe Online Bazinga! A team of researchers from the University of Melbourne and RMIT University has postulated an alternative theory for the start of the Universe. Instead of a Big Bang, they say the Universe more likely started with a Big Freeze. The research team suggests that our understanding of the Universe could be revolutionized by investigating the cracks and crevices common to all crystals, including ice. The Big Bang theory is a...

Watch the Video: Recreating a Slice of the Universe Lee Rannals for redOrbit.com - Your Universe Online Scientists have found a way to accurately follow the birth and evolution of thousands of galaxies over billions of years. For the first time, scientists at the Harvard-Smithsonian Center for Astrophysics (CfA) and their colleagues at the Heidelberg Institute for Theoretical Studies (HITS) have made it possible to build a universe from scratch that brims with galaxies like we...

Gamma-ray photons seen emanating from the center of the Milky Way galaxy are consistent with the intriguing possibility that dark-matter particles are annihilating each other in space, according to research submitted by UC Irvine astrophysicists to the American Physical Society journal Physical Review D. Kevork Abazajian, assistant professor, and Manoj Kaplinghat, associate professor, of the Department of Physics & Astronomy analyzed data collected between August 2008 and June 2012...

There's Plenty Of Dark Matter Near The Sun
2012-08-09 14:54:46

April Flowers for redOrbit.com - Your Universe Online Astronomers at the University of Zurich, ETH Zurich, the University of Leicester and NOAC Beijing have found large amounts of invisible "dark matter" near the Sun. They also found tantalizing hints of a new dark matter component within our own galaxy. The study results, which will be published in the journal Monthly Notices of the Royal Astronomical Society, are consistent with the theory that the Milky Way is surrounded by a massive...

April Flowers for redOrbit.com - Your Universe Online The largest-ever 3-D map of massive galaxies and distant black holes was released this week in the hopes that it will help explain the mysteries of "dark matter" and "dark energy." This new sky map is the work of the Sloan Digital Sky Survey III (SDSS-111) collaboration. SDSS-III is mission is to map the Milky Way, search for extrasolar planets, and solve the mystery of dark matter. The research team began to gather data in 2008 for...

First Public Data Release From The Baryon Oscillation Spectroscopic Survey (BOSS)
2012-08-08 10:08:02

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 The Third Sloan Digital Sky Survey (SDSS-III) has issued Data Release 9 (DR9), the first public release of data from the Baryon Oscillation Spectroscopic Survey (BOSS). In this release BOSS, the largest of SDSS-III's four surveys, provides spectra for 535,995 newly observed galaxies, 102,100 quasars, and 116,474...

$3 Million Fundamental Physics Prize Won By Stanford Physicist
2012-08-01 08:21:00

Stanford physics Professor Andrei Linde has been named an inaugural winner of the $3 million Fundamental Physics Prize. The award recognizes Linde's work developing cosmic inflation theory, a modification on big bang theory that generates a more accurate description of the birth of the universe. Andrei Linde freely admits that when he began developing theories of cosmic inflation in the early 1980s, the concept seemed like pure science fiction. But, as experimental data has verified his...

Dark energy makes up about 70 percent of the current content of the Universe and thus holds the ultimate fate of our Universe. Several possible scenarios are possible depending on the properties of dark energy; one is that the Universe will end in a so-called big rip. This interesting topic was recently explored by five researchers from the University of Science and Technology of China, the Institute of Theoretical Physics at the Chinese Academy of Sciences, Northeastern University, and...

Astronomers have puzzled over why some puny, extremely faint dwarf galaxies spotted in our Milky Way galaxy's back yard contain so few stars. These ghost-like galaxies are thought to be some of the tiniest, oldest, and most pristine galaxies in the universe. They have been discovered over the past decade by astronomers using automated computer techniques to search through the images of the Sloan Digital Sky Survey. But astronomers needed NASA's Hubble Space Telescope to help solve the...

Lee Rannals for redOrbit.com - Your Universe Online The Hubble Space Telescope has helped scientists unravel the mystery of the extremely faint dwarf galaxies. These galaxies are thought to be some of the tiniest, oldest and most pristine galaxies in the universe. They have been discovered over the past decade by astronomers using automated computer techniques to search through the images of the Sloan Digital Sky Survey. The Hubble has given scientists views of three of the small-fry...

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. Credit: NASA/Wikipedia What is Cosmology? I once commented to an acquaintance that I was fascinated by the field of Cosmology, and mused that if I had more time, I...

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 × 1015 M☉ 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 -04° 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...
