Hubble Reveals Deepest View  Ever Of The Universe
2012-09-26 05:09:28

April Flowers for redOrbit.com - Your Universe Online Researchers using the Hubble Telescope have assembled a new and improved portrait of our deepest-ever view of the Universe. The eXtreme Deep Field (XDF) photo was compiled by combining ten years worth of NASA and ESA Hubble Space Telescope observations taken of a patch of sky within the original Hubble Ultra Deep Field. The Hubble Ultra Deep Field is a small area of space in the Fornax (The Furnace) constellation created using Hubble...

Milky Way Surrounded By Halo
2012-09-24 19:28:01

Lee Rannals for redOrbit.com — Your Universe Online The Milky Way Galaxy is known for its spirals, as well as Earth's home in the cosmos, but now it will also be known as a galaxy that features a halo. Astronomers using NASA's Chandra X-ray Observatory found evidence that the Milky Way Galaxy is embedded in a halo of hot gas that extends for hundreds of thousands of light years. Scientists estimated that the mass of the halo found is comparable to the mass of all the stars in...

Artificial Intelligence Maps The Universe
2012-09-24 11:48:59

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have developed an algorithm that is able to chart and explain accurately the structure and dynamics of the universe. The team developed a new algorithm based on artificial intelligence which provides results that are close to the observed distribution of motion and galaxies. It has been hard for astronomers to explain the distribution of galaxies. Five percent of the universe is made of normal matter, making up the...

Spitzer And Hubble Telescopes Discover Furthest Galaxy Ever
2012-09-19 19:01:35

Lee Rannals for redOrbit.com — Your Universe Online A long time ago, in a galaxy far, far away, light took off, then traveled 13.2 billion light-years until it was finally picked up by NASA's telescopes. Astronomers have identified the furthest galaxy ever using NASA's Spitzer and Hubble space telescopes. The light captured by the telescope was from when the universe was just 500 million years old, according to NASA. "This galaxy is the most distant object we have ever...

Lee Rannals for redOrbit.com — Your Universe Online Researchers are finding ways to map out the spread and structure of the universe through the light of quasars. Scientists have developed a technique that could offer up a never before seen look back to a time just after the Big Bang. They found, while analyzing the visible light from a small group of quasars, that patterns of light variation over time were consistent from one quasar to another when corrected for the celestial...

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...

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...
