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.

Astronomers using the National Science Foundation's Very Large Array (VLA) radio telescope have gained tantalizing insights into the nature of the most distant object ever observed in the Universe -- a gigantic stellar explosion known as a Gamma Ray Burst (GRB).

The ALMA (Atacama Large Millimeter/submillimeter Array) astronomical observatory took another step forward and upward, as one of its state-of-the-art antennas was carried for the first time to Chile's 16,500-foot-high plateau of Chajnantor on the back of a giant, custom-built transporter.

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...
