Latest National Radio Astronomy Observatory Stories
Radio astronomers have directly measured the distance to a faraway galaxy, providing a valuable "yardstick" for calibrating large astronomical distances and demonstrating a vital method that could help determine the elusive nature of the mysterious Dark Energy that pervades the Universe.
The chance discovery last month of a rare radio supernova - an exploding star seen only at radio wavelengths and undetected by optical or X-ray telescopes - underscores the promise of new, more sensitive radio surveys to find supernovas hidden by gas and dust.
Astronomers have discovered a unique double-star system that represents a "missing link" stage in what they believe is the birth process of the most rapidly-spinning stars in the Universe -- millisecond pulsars.
Scientists and engineers working on the world's largest ground-based astronomical project, the Atacama Large Millimeter/submillimeter Array (ALMA), have achieved another milestone â€” the successful linking of two ALMA astronomical antennas, synchronized with a precision of one millionth of a millionth of a second â€” to observe the planet Mars.
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.
ALMA is on its way to developing observational capabilities with resonance 10 times that of the current state of the art.
CHARLOTTESVILLE, Va., Feb. 6 /PRNewswire/ -- Astronomers celebrated today the formal acceptance of the first North American antenna by the Joint ALMA Observatory.
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.
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.
High in the Atacama region in northern Chile, one of the world's most advanced telescopes has just passed a major milestone.
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...
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...
Kitt Peak Observatory -- astronomical observatory located southwest of Tucson, Ariz.; it was founded in 1958 under contract with the National Science Foundation and is administered by the Association of Universities for Research in Astronomy. Its principal instrument is the Mayall 158-in. (4-m) reflector. The observatory's equipment also includes 84-in. (2.1 m), 50-in. (1.3-m), 36-in. (0.9-m), and 16-in. (0.4-m) reflecting telescopes as well as a planned 3.5-m telescope. Used for wide...
