Dark Energy Almost 100 Percent Proven?
2012-09-13 09:56:52

April Flowers for redOrbit.com - Your Universe Online Since the 1990's, dark energy has been the most accepted hypothesis to explain the expansion rate of the Universe. A hypothetical form of energy, dark energy is thought to permeate all of space and accounts for about 73% of the total mass-energy of the universe. According to a team of astronomers from the University of Portsmouth and LMU University Munich, dark energy isn't so theoretical anymore. They say, it is really there....

Howard Bloom, who´s been called “the next Stephen Hawking” and the “Einstein, Newton, Darwin, and Freud of the 21st Century,” has written a monumental new tome for anyone curious about the beginning, middle, and end of the cosmos. Brooklyn, NY (PRWEB) September 10, 2012 How does an inanimate universe manage the God-like feat of creating itself from absolutely nothing? And what enables it, after pulling itself up by its own cosmic bootstraps, to continue to...

April Flowers for redOrbit.com — Your Universe Online A team of astrophysicists from the Center for Astrophysics at the University of Notre Dame are exploring a discrepancy between the amount of lithium predicted by the standard models of elemental production during the Big Bang and the amount of lithium observed in the gas of the Small Magellanic Cloud. The Small Magellanic Cloud is a dwarf galaxy with a diameter of about 7,000 light-years.  It contains several hundred...

Early Universe Lit Up By Explosion Of Growth
2012-09-07 05:29:14

April Flowers for redOrbit.com - Your Universe Online A new study from the University of California, Berkeley indicates that the birth of the first massive galaxies that lit up the early universe was an explosive event, happening faster and ending sooner than suspected. Around 13 billion years ago, when the universe was about 750 million years old, extremely bright, active galaxies formed and fully illuminated the universe, according to Oliver Zahn, a postdoctoral fellow at the Berkeley...

Big Bang Tracked With Hydrogen Atoms

April Flowers for redOrbit.com - Your Universe Online If the eyes are the windows to your soul, the stars are the windows to our galactic past because they can unveil the history of our Universe. The farther away a star is, the older it is. The Universe is estimated to be 14 billion years old, but our current telescopes can only see galaxies about 700 million years old and only then when the galaxy is unusually large or as the result of a big event like a stellar explosion. An...

Dark Matter Mystery Close To Being Solved
2012-09-05 05:25:36

April Flowers for redOrbit.com - Your Universe Online Dark matter comprises a large portion of the Universe, filling the space between galaxies and stars. Since the prediction of dark matter some 70 years ago, researchers from a myriad of disciplines — astronomers, cosmologists, and even particle physicists — have been looking for answers to what dark matter could be. New observations from the Planck satellite may bring researchers from the Niels Bohr Institute closer than...

Supernova Lights Up The Galactic Scene
2012-08-31 12:06:23

April Flowers for redOrbit.com - Your Universe Online A recent study, led by Edo Berger of Harvard University, made the most of a dying star's fury to probe a distant galaxy some 9.5 billion light years away. The most distant stellar explosion of its kind ever studied, that dying star lit up the galactic scene. “It´s like someone turned on a flashlight in a dark room and suddenly allowed us to see, for a short time, what this far-off galaxy looks like, what it is composed...

Brett Smith for redOrbit.com - Your Universe Online A debate that has been raging over the distribution of matter in the universe can finally be put to bed thanks to the WiggleZ Dark Matter survey that was conducted over 276 nights from August 2006 to January 2011. The majority of physicists believe that the matter in the universe is distributed evenly on the largest scales and this outlook has fueled everything from Einstein´s equations to calculations that are the foundation for...

Johns Hopkins University professor Charles L. Bennett and members of the Wilkinson Microwave Anisotropy Probe (WMAP) space mission that he led will receive the Gruber Foundation´s 2012 Cosmology Prize in Beijing, China tomorrow. Bennett and the 26-member WMAP team will share the $500,000 prize and are being recognized by the foundation for their transformative study of an ancient light dating back to the infant universe. So precise and accurate are the WMAP results that they form the...

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...

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...
