Processes that laid the foundation for life on Earth -- star and planet formation and the production of complex organic molecules in interstellar space -- are yielding their secrets to astronomers armed with powerful new research tools, and even better tools soon will be available. Astronomers described three important developments at a symposium on the "Cosmic Cradle of Life" at the annual meeting of the American Association for the Advancement of Science in Chicago, IL. In one development,...

CHARLOTTESVILLE, Va., Feb. 6 /PRNewswire/ -- Astronomers celebrated today the formal acceptance of the first North American antenna by the Joint ALMA Observatory. ALMA, the Atacama Large Millimeter/submillimeter Array, is a gathering armada of short-wavelength radio telescopes whose combined power will enable astronomers to probe with unprecedented sharpness phenomena and regions that are beyond the reach of visible-light telescopes. The observatory is being assembled high in the Chilean...

Black holes may have come before the formation of galaxies, astronomers reported on Wednesday, adding information that could provide new insights into the nature of the mysterious invisible black objects. At the  213th meeting of the American Astronomical Society in Long Beach, California, researchers said they discovered a clear link between the mass of a black hole and the galaxy where it was spotted. "It looks like the black holes came first. The evidence is piling up," said Chris...

Experts say the Green Bank Observatory in West Virginia is under an audio assault from wireless computers and other gadgets cluttering the same frequencies occupied by signals from neutron stars. Wesley Sizemore is an interference hunter, vigilantly pursuing stray electromagnetic signals that bedevil researchers at the National Radio Astronomy Observatory, which sits on 13,000 square miles tucked away in the nation's only radio-free quiet zone. He and other scientists at the observatory...

High in the Atacama region in northern Chile, one of the world's most advanced telescopes has just passed a major milestone. The first of many state-of-the-art antennas has just been handed over to the Atacama Large Millimeter/submillimeter Array (ALMA) project. ALMA is under construction on the plateau of Chajnantor, at an altitude of 5000 m. The telescope is being built by a global partnership, including ESO as the European partner. ALMA will initially comprise 66 high precision antennas,...

Astronomers have discovered a rare type of star called a pulsar that they believe is locked in an elongated orbit around a star much like the sun. The spinning pulsar is called J1903+0327 and is located about 21,000 light years (About 6 trillion miles) from Earth. A pulsar is created when a massive star explodes as a supernova, astronomers said."The big question is"”how in the heck did this thing form, because it doesn't follow our standard models of how these things form," astronomer...

A team of scientists and engineers led by the Naval Research Laboratory (NRL) will study how to design a telescope on the Moon for peering into the last unexplored epoch in the Universe's history. NASA has announced that it will sponsor a series of studies focusing on next-generation space missions for astronomy. These studies will contribute to the Decadal Survey, an effort undertaken every 10 years by astronomers and physicists to help establish priorities for future research directions in...

In the thin, dry air of northern Chile's Atacama Desert, at an altitude of 16,500 feet, an amazing new telescope system is taking shape, on schedule to provide the world's astronomers with unprecedented views of the origins of stars, galaxies, and planets. The Atacama Large Millimeter/submillimeter Array (ALMA) will open an entirely new "window" on the Universe, allowing scientists to unravel longstanding and important astronomical mysteries. "Most of the photons in the Universe are in the...

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...
