The Low Frequency Array (LOFAR), a new pan-European radio astronomy facility, has started mapping the Universe at very low energy wavelengths, a part of the electromagnetic spectrum that is relatively unexplored. It will detect faint signals from the first stars and mini-black holes that emerged when the Universe was only 500 000 years old "“ and will also be looking for signs of other civilizations in the Universe closer to home. Dr John McKean will present the first images at the RAS...

On March 30 and 31 a strategic international workshop on the Square Kilometer Array (SKA) will seek to identify the major economical and societal benefits of large-scale scientific research infrastructure investments. The SKA is a USD 1 billion+ international project to create a radio telescope incorporating a receiving surface of a million square meters, fifty times larger than the biggest receiving surface now in existence. This huge surface will be composed of many small antennas, divided...

Like a hard-driving athlete whose joints need help, the giant "Mars antenna" at NASA's Deep Space Network site in Goldstone, Calif. has begun major, delicate surgery. The operation on the historic 70-meter-wide (230-foot) antenna, which has received data and sent commands to deep space missions for over 40 years, will replace a portion of the hydrostatic bearing assembly. This assembly enables the antenna to rotate horizontally. The rigorous engineering plans call for lifting about 4 million...

NASA officials broke ground near Canberra, Australia on Wednesday, Feb. 24, beginning a new antenna-building campaign to improve Deep Space Network communications. Following the recommendations of an independent study, NASA embarked on an ambitious project to replace its aging fleet of 70-meter-wide (230-foot-wide) dishes with a new generation of 34-meter (112-foot) antennas by 2025. The three 70-meter antennas, located at the NASA Deep Space Network complexes at Goldstone, Calif., Madrid,...

An international team of scientists, including several astronomers from the Joint Institute for VLBI in Europe (JIVE) and the Netherlands Institute for Radio Astronomy (ASTRON), both located in Dwingeloo, have observed a supernova with peculiar radio emission. In a paper to be published in the January 28, 2010 issue of Nature, the team led by JIVE's Zsolt Paragi reports, for the first time ever, detection of a relativistic outflow in a Type Ic supernova, thus supporting the link with the even...

Astronomers have found a giant magnetic loop stretched outward from one of the stars making up the famous double-star system Algol. The scientists used an international collection of radio telescopes to discover the feature, which may help explain details of previous observations of the stellar system. "This is the first time we've seen a feature like this in the magnetic field of any star other than the Sun," said William Peterson, of the University of Iowa. The pair, 93 light-years from...

The Atacama Large Millimeter/submillimeter Array (ALMA) has passed a key milestone crucial for the high quality images that will be the trademark of this revolutionary new tool for astronomy. Astronomers and engineers have, for the first time, successfully linked three of the observatory's antennas at the 5000-meter elevation observing site in northern Chile. Having three antennas observing in unison paves the way for precise images of the cool Universe at unprecedented resolution, by...

NEWTON, N.C., Nov. 20 /PRNewswire/ -- The first of 25 North American antennas to be manufactured by General Dynamics SATCOM Technologies for the Atacama Large Millimeter/Submillimeter Array (ALMA) astronomical observatory was recently installed at the ALMA Operations Site located high in the Chilean Andes. Traveling on a custom-built transporter from the ALMA Operations Support Facility at 9,500 feet above sea level, the 12-meter, 100-ton antenna made a 22-mile trek to the Array...

A team of astronomers and engineers at the Atacama Large Millimeter/submillimeter Array (ALMA) have made the first interferometric measurements of radio signals "” so-called "fringes" "” of an astronomical source from the observatory's 5000-meter "high site" of Chajnantor. This is an important technical step for ALMA, as it used a full suite of the production equipment, including two of the 12-meter diameter antennas, and sophisticated electronic systems for receiving and...

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...
