Black Hole Birth Announcement
2011-11-17 14:40:32

For the first time, astronomers have produced a complete description of a black hole, a concentration of mass so dense that not even light can escape its powerful gravitational pull. Their precise measurements have allowed them to reconstruct the history of the object from its birth some six million years ago. Using several telescopes, both ground-based and in orbit, the scientists unraveled longstanding mysteries about the object called Cygnus X-1, a famous binary-star system discovered...

APEX Provides New View Of Carina Nebula Star Formation
2011-11-16 10:11:45

[ Watch the Video ] Observations made with the APEX telescope in submillimeter-wavelength light reveal the cold dusty clouds from which stars form in the Carina Nebula. This site of violent star formation, which plays host to some of the highest-mass stars in our galaxy, is an ideal arena in which to study the interactions between these young stars and their parent molecular clouds. Using the LABOCA camera on the Atacama Pathfinder Experiment (APEX) telescope on the plateau of...

New Telescope Opens For Business In Chile's Atacama Desert
2011-10-03 09:36:24

[ Watch the Video ] Astronomers have opened up its doors to a new ground-base telescope that will help give scientists a peak at the places that have never been explored. The Atacama Large Millimeter/submillimeter Array (ALMA) has released an image of a merging pair of galaxies as part of its grand opening. ALMA is the largest and most expensive radio observatory on Earth and was funded by several different space agencies. Radio observatories collect tiny waves given off by the...

Countries Battle It Out For The Square Kilometer Array Project
2011-09-15 11:48:09

  The world´s biggest telescope, the Square Kilometer Array (SKA), is set to be built in one of two locations depending on the outcome of bidding, which starts today. The $2 billion project will consist of thousands of dishes stretching out 1,900 miles, with a total surface area of one square kilometer. The system will generate enough raw data to fill 15 million 64Gb iPods every day, and will require a supercomputer 1,000 times faster -- equivalent to a billion PCs -- than...

Cryogenic Catering Truck Comes To ALMA Observatory
2011-09-04 05:28:16

  The ultimate in high altitude, high-tech catering has arrived in Chile to serve chilled "provisions" to the telescopes at the largest astronomical complex in the world, the Atacama Large Millimeter/submillimeter Array (ALMA). Until now, servicing the state-of-the-art superconducting receivers inside an ALMA telescope has required hauling the entire 115-ton telescope from its observing site at 16,500 feet down to a support facility at 9,500 feet. The dangerous 40-mile roundtrip,...

A New Atlas Of The Milky Way
2011-08-31 07:49:27

  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...

Getting ready for ALMA's first scientific observations The first European antenna for the Atacama Large Millimeter/submillimeter Array (ALMA) has reached new heights, having been transported to the observatory's Array Operations Site (AOS) on 27 July 2011. The 12-meter diameter antenna has arrived at the Chajnantor plateau, 5000 meters above sea level. Here, it joins antennas from the other international ALMA partners, bringing the total number at the AOS to 16. Although 16 sounds like just...

A Russian radio telescope intended to be the largest of its kind in space, has started its stellar orbit around planet Earth for the first time since being launched, reports BBC News. The radio telescope, named RadioAstron, part of the Russian space observatory -- Spectrum-R -- will travel in an elliptical orbit that at its farthest point from Earth will take it close to the Moon. It was carried into orbit by the Zenith-3M rocket, taking off from Kazakhstan's Baikonur Cosmodrome on Monday...

Very Large Array -- The Very Large Array, one of the world's premier astronomical radio observatories, consists of 27 radio antennas in a Y-shaped configuration on the Plains of San Agustin fifty miles west of Socorro, New Mexico. Each antenna is 25 meters (82 feet) in diameter. The data from the antennas is combined electronically to give the resolution of an antenna 36km (22 miles) across, with the sensitivity of a dish 130 meters (422 feet) in diameter. The VLA is an...

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...

Radio Astronomy -- Radio astronomy is the study of celestial phenomena through measurement of the characteristics of radio waves emitted by physical processes occurring in space. Radio waves are much longer than light waves. In order to receive good signals, radio astronomy requires large antennas. Radio astronomy is a relatively new field of astronomical research. The earliest investigations into extraterrestrial sources of radio waves were by Karl Guthe Jansky, an engineer with Bell...

National Radio Astronomy Observatory -- The National Radio Astronomy Observatory (NRAO) is a research facility of the U.S. National Science Foundation. They provide state-of-the-art radio telescope facilities for use by the scientific community. They conceive, design, build, operate and maintain radio telescopes used by scientists from around the world. Scientists use their facilities to study virtually all types of astronomical objects known, from planets and comets in our own Solar...

Jodrell Bank Observatory -- The Jodrell Bank Observatory, near Macclesfield, Cheshire in the north west of England is a part of the University of Manchester. It has played an important part in the research into quasars and pulsars, as well as the first detection of a gravitational lens in 1979, confirming one of Einstein's theories. It was established in 1945 by Dr. Bernard Lovell, who wanted to investigate cosmic rays after his work on radar in World War II. The first radio...
