  Sino-German research group draws a new map at the Urumqi radio telescope and discovers two supernova remnants It may not be much use to hitchhikers through the galaxy, but it is extremely valuable to astronomers: the new radio atlas of the Milky Way. After almost ten years of work, researchers at the Max Planck Society and the Chinese Academy of Sciences have completed their investigation into the polarized radio emission in the galactic plane. The atlas is based on observations...

  A galaxy with a combination of characteristics never seen before is giving astronomers a tantalizing peek at processes they believe played key roles in the growth of galaxies and clusters of galaxies early in the history of the Universe. The galaxy, dubbed Speca by the researchers, is only the second spiral, as opposed to elliptical, galaxy known to produce large, powerful jets of subatomic particles moving at nearly the speed of light. It also is one of only two galaxies to show...

  An international team of astronomers has discovered an exotic planet that appears to be made of diamond orbiting a tiny star in our galaxy. The new planet, which is far denser than any other previously known, consists primarily of carbon.  However, its high density has led scientists to calculate the carbon must be crystalline, meaning a large part of the planet would effectively be diamond. "The evolutionary history and amazing density of the planet all suggest it is...

A team of astronomers have discovered the largest and farthest reservoir of water ever detected in the universe. The researchers found a mass of water vapor that is at least 140 trillion times that of all water in the world's oceans combined, and 100,000 times more massive than the sun. The team said the light has taken 12 billion years to reach Earth, and the astronomers were observing the light when the universe was just 1.6 billion years old. "The environment around this quasar is unique...

Whether on their own or orbiting as a pair, black holes don't typically sit still. Not only do they spin, they can also move laterally across their host galaxy. And according to astrophysicists at Brigham Young University, both types of movement power massive jets of energy known as quasars. The study, which appears in the current issue of Proceedings of the National Academy of Sciences (PNAS), is the first to compute what may fuel some of the brightest persistent lights in the universe....

The discovery potential of the future international SKA radio telescope has been glimpsed following the commissioning of a working optical fibre link between CSIRO's Australian SKA Pathfinder (ASKAP) telescope in Western Australia, and other radio telescopes across Australia and New Zealand. The achievement will be announced at the 2011 International SKA Forum, taking place this week in Banff, Canada. On 29 June, six telescopes "“ ASKAP, three CSIRO telescopes in New South Wales, a...

Astronomers are puzzled by the announcement that the masses of the largest objects in the Universe appear to depend on which method is used to weigh them. The new work was presented at a specialist discussion meeting on 'Scaling Relations of Galaxy Clusters' organized by the Astrophysics Research Institute (ARI) at Liverpool John Moores University and supported by the Royal Astronomical Society. Clusters of galaxies are the largest gravitationally bound objects in the Universe containing...

WASHINGTON, June 15, 2011 /PRNewswire-USNewswire/ -- Using the deepest X-ray image ever taken, astronomers found the first direct evidence that massive black holes were common in the early universe. This discovery from NASA's Chandra X-ray Observatory shows that very young black holes grew more aggressively than previously thought, in tandem with the growth of their host galaxies.

Early results from dramatically upgraded telescope show breadth of scientific impact A new and uniquely powerful tool for cutting-edge science is emerging on the crisp, high desert of western New Mexico. Outwardly, it looks much the same as the famed Very Large Array (VLA), a radio telescope that has spent more than three decades on the frontiers of astronomical research. The 27 white, 230-ton dish antennas still peer skyward, the 72 miles of railroad track still wait to transport the...

Berkeley Lab-led BOSS proves it can do the job with quasars The biggest 3-D map of the distant universe ever made, using light from 14,000 quasars "“ supermassive black holes at the centers of galaxies billions of light years away "“ has been constructed by scientists with the third Sloan Digital Sky Survey (SDSS-III). The map is the first major result from the Baryon Oscillation Spectroscopic Survey (BOSS), SDSS-III's largest survey, whose principal investigator is David Schlegel...

Image Caption: NGC 4414, a typical spiral galaxy in the constellation Coma Berenices, is about 56,000 light-years in diameter and approximately 60 million light-years distant. Credit: NASA/ESA/Wikipedia What is Astrophysics? For much of the modern age the term Astrophysics has been used synonymously with Astronomy. This interchange is so common that many textbooks even offer the two as having the same meaning. However, from a strictly historical perspective there are differences...

Radio telescopes, used in tracking and collecting data from satellites and space probes, are a form of directional radio antenna used in radio astronomy. They operate on the radio frequency portion of the electromagnetic spectrum where they detect radio sources. Radio telescopes are large parabolic antennas used singly or in an array and are located far from major centers of population in order to avoid electromagnetic interference. Karl Guthe Jansky built the first radio antenna used to...

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...

Yakov Borisovich Zel'dovich (March 8, 1914 "“ December 2, 1987) was a productive Soviet physicist. He was instrumental in the advancement of Soviet nuclear and thermonuclear weapons, and also was an invaluable assistance in the fields of adsorption and catalysis, shock waves, nuclear physics, particle physics, astrophysics, physical cosmology, and general relativity. In 1914, he was born into a Jewish family in Minsk, now called Belarus. Four months after his birth, he and his family...

Radio Telescope -- In contrast to an ordinary telescope, which produces visible light images, a radio telescope "sees" radio waves emitted by radio sources located anywhere in the Universe, typically by means of a large parabolic ("dish") antenna, or arrays of them. The best-known (and largest) radio telescope is in Arecibo, Puerto Rico. A well-known radio telescope being an array of antennae is the Very Large Array (VLA) in Socorro, New Mexico. The largest (100-meter diameter) and most...
