University of Texas astronomers use Lonestar supercomputer to explore role of dark matter in galaxy formation From Earth, observers use telescopes to look and learn about the distant luminous spheres. But the telescope often isn't the only instrument used. Karl Gebhardt, professor of astrophysics at The University of Texas at Austin and one of the principal investigators for the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) project, makes revolutionary discoveries about dark...

Scientists Discover New Submillimeter Galaxy
2012-06-23 04:56:58

Using an array of radio telescopes, researchers from Europe and Japan have discovered a submillimeter galaxy -- a type of galaxy that has intense star formation activity and is covered by large amounts of dust -- located approximately 12.4 billion light-years away. The international team of experts, which was led by Kyoto University Associate Professor Tohru Nagao, used the Atacama Large Millimeter/submillimeter Array (ALMA) in southern Chile to locate the galaxy, the researchers announced...

Charles L. Bennett and the Wilkinson Microwave Anisotropy Probe (WMAP) team are the recipients of the 2012 Gruber Cosmology Prize. Their observations and analyses of ancient light have provided the unprecedentedly rigorous measurements of the age, content, geometry, and origin of the universe that now comprise the Standard Cosmological Model. The Prize citation further recognizes that the exquisite specificity of these results has helped transform cosmology itself from “appealing...

Small Planets Less Pickier For Host Stars Than Previously Thought

Lee Rannals for redOrbit.com [ Watch the Video ] New observations show that small planets may be more widespread in our galaxy than previously thought. Lars A. Buchhave, an astrophysicist at the Niels Bohr Institute and the Centre for Star and Planet Formation at the University of Copenhagen, and colleagues studied the composition of over 150 stars harboring 226 planet candidates smaller than Neptune for the research. Scientists previously thought that the formation of small...

Theories of the primordial Universe predict the existence of knots in the fabric of space - known as cosmic textures - which could be identified by looking at light from the cosmic microwave background (CMB), the relic radiation left over from the Big Bang. Using data from NASA's Wilkinson Microwave Anisotropy Probe (WMAP) satellite, researchers from UCL, Imperial College London and the Perimeter Institute have performed the first search for textures on the full sky, finding no evidence...

Hidden Patterns Of Light Revealed By Spitzer
2012-06-08 03:30:50

The faint, lumpy glow given off by the very first objects in the universe may have been detected with the best precision yet, using NASA's Spitzer Space Telescope. These faint objects might be wildly massive stars or voracious black holes. They are too far away to be seen individually, but Spitzer has captured new, convincing evidence of what appears to be the collective pattern of their infrared light. The observations help confirm the first objects were numerous in quantity and furiously...

More atomic hydrogen gas – the ultimate fuel for stars – is lurking in today´s Universe than we thought, CSIRO astronomer Dr Robert Braun has found. This is the first accurate measurement of this gas in galaxies close to our own. Just after the Big Bang the Universe´s matter was almost entirely hydrogen atoms. Over time this gas of atoms came together and generated galaxies, stars and planets – and the process is still going on. Astronomers want to understand...

Universe At Peak Observation Period 13 Billion Years Ago
2012-05-23 11:22:26

Lee Rannals for RedOrbit.com Harvard-Smithsonian Center for Astrophysics theorist Avi Loeb says that modern time is not the ideal scenario to study the universe, but rather about 13 billion years ago was. Loeb said that according to his new calculations, just about 500 million years after the Big Bang proves to be the best-case scenario when studying our cosmos.  He says that the farther you go into the future, the more information you lose, making our time period better than those...

Baby Galaxies Grew Up Faster Than Previously Believed
2012-05-18 03:53:28

[ Watch the Video ] Baby galaxies from the young Universe more than 12 billion years ago evolved faster than previously thought, shows new research from the Niels Bohr Institute. This means that already in the early history of the Universe, there was potential for planet formation and life. The research results have been published in the scientific journal, Monthly Notices of the Royal Astronomical Society Letters. For several thousand years after the Big Bang 13.7 billion years ago,...

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...
