Green Bank Telescope's staff typically spend their days helping scientists carry out their research, but on one dramatic day in February 2010, they helped rescue soldiers from a crashed helicopter The National Radio Astronomy Observatory's (NRAO) Robert C. Byrd Green Bank Telescope  (GBT) is the world's largest fully steerable telescope, an incredibly sensitive instrument that can detect complex molecules such as sugar (glycoaldehyde) in space, measure minuscule fluctuations in...

Don Backer, a professor in the Department of Astronomy at the University of California, Berkeley, and a world leader in the field of radio astronomy, died on Sunday, July 25, after collapsing outside his home. He was 66. Backer joined the UC Berkeley Astronomy Department in 1975; since 1989, he held a position both as a full professor in astronomy and as a researcher in the department's Radio Astronomy Laboratory (RAL). He served as chair of the department from 1998-1999 and from 2002-2008,...

Mapping large-scale cosmic structures will help test theories Pioneering observations with the National Science Foundation's giant Robert C. Byrd Green Bank Telescope (GBT) have given astronomers a new tool for mapping large cosmic structures. The new tool promises to provide valuable clues about the nature of the mysterious "dark energy" believed to constitute nearly three-fourths of the mass and energy of the Universe. Dark energy is the label scientists have given to what is causing the...

Workers at NASA's Deep Space Network complex in Goldstone, Calif., have been making precise, laser-assisted measurements to ensure a flat surface for pouring new grout as part of a major renovation on the 70-meter-wide (230-foot-wide) "Mars antenna." While officially dubbed Deep Space Station 14, the antenna picked up the Mars name from its first task: tracking NASA's Mariner 4 spacecraft, which had been lost by smaller antennas after its historic flyby of Mars. This work represents the first...

An international team of scientists including University of British Columbia astronomer Ingrid Stairs has discovered a promising way to fine-tune pulsars into the best precision time-pieces in the Universe. The discovery could give astronomers a new tool to study the powerful gravitational forces that shaped the universe. Pulsars--incredibly fast spinning collapsed stars--have been studied in great detail since their discovery in 1967. The extremely stable rotation of these 'cosmic clocks'...

Scientists unveiled the largest radiotelescope in the world on Saturday in the Netherlands. Femke Boekhorst of the Netherlands Radioastronomy Institute said the LOFAR (LOw Frequence ARray) consists of 25,000 small antennas measuring between 19 inches and 6 feet across, instead of a traditional large dish. The scientists say the telescope was capable of detecting faint signals from almost as far back as the Big Bang. The antennas are spread out across the Netherlands and also in Germany,...

Surveying the sky, XMM-Newton has discovered two massive galaxy clusters, confirming a previous detection obtained through observations of the Sunyaev-Zel'dovich effect, the 'shadow' they cast on the Cosmic Microwave Background. The discovery, made possible thanks to a novel mosaic observing mode recently introduced on ESA's X-ray observatory, opens a new window to study the Universe's largest bound structures in a multi-wavelength approach. Galaxy clusters are the largest gravitationally...

Astronomers studying the Milky Way have discovered a large number of previously-unknown regions where massive stars are being formed. Their discovery provides important new information about the structure of our home Galaxy and promises to yield new clues about the chemical composition of the Galaxy. "We can clearly relate the locations of these star-forming sites to the overall structure of the Galaxy. Further studies will allow us to better understand the process of star formation and to...

The SKA Program Development Office (SPDO) announced on May 11 the appointment of Mr Kobus Cloete to the role of Project Manager and Dr Minh Huynh to the role of Deputy International SKA Project Scientist. The appointments are made at a crucial stage in the finalization of the design for the world's largest radio telescope. Kobus will lead the growing international SKA development team and coordinate work on the technical design of the telescope. He gained extensive experience working in the...

Pulsars in many octaves A unique combination of telescopes allowed astronomers to simultaneously observe the radio wavelength light from six different pulsars across wavelengths from only 3.5 centimetres up to 7 metres - a difference-factor of 200, providing an unprecedented view of how radio pulsars shine. For this world record in wavelength coverage, the international team, including scientists from the Max Planck Institute for Radio Astronomy, used the new European LOFAR telescope, in...

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...
