$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...

Dark Galaxies Of The Early Universe Seen For The First Time
2012-07-11 17:25:51

Dark galaxies are small, gas-rich galaxies in the early Universe that are very inefficient at forming stars. They are predicted by theories of galaxy formation and are thought to be the building blocks of today's bright, star-filled galaxies. Astronomers think that they may have fed large galaxies with much of the gas that later formed into the stars that exist today. Because they are essentially devoid of stars, these dark galaxies don't emit much light, making them very hard to detect....

Dark galaxies spotted for the first time

Lee Rannals for redOrbit.com - Your Universe Online Dark galaxies may have been spotted for the very first time using the European Space Observatory's Very Large Telescope (VLT). An international team of astronomers believe they have detected these elusive objects by observing them as they were lit up by glowing quasars. Dark galaxies are very small, gas-rich galaxies in the early universe that are inefficient at forming stars. Scientists believe these galaxies are building blocks of...

Lee Rannals for redOrbit.com - Your Universe Online For the first time, scientists have detected part of the invisible dark matter skeleton of the universe, where over half of all matter is believed to reside. The discovery confirms a key prediction in the theory of how the universe's current web-like structure came to be. The map of the known universe shows that most galaxies are organized into clusters, but some are situated along filaments that connect to the clusters....

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...

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...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
