Astronomers have made the first radio-telescope images of a powerful coronal mass ejection on the Sun, giving them a long-sought glimpse of hitherto unseen aspects of these potentially dangerous events.
Astronomers have used the National Science Foundation’s Very Long Baseline Array radio telescope to do a very detailed map of the magnetic field within a star-forming cloud.
Astronomers using the National Science Foundation’s 140-foot radio telescope at the National Radio Astronomy Observatory in Green Bank, W.Va., have discovered a highly unusual, massive interstellar cloud that appears poised to begin a burst of star formation.
A team of observers used a gamma-ray burst as a powerful tool to unveil the nature of the galaxy in which it occurred, more than 7 billion light-years away.
Astronomers using a world-wide collection of radio telescopes, including the National Science Foundation’s Very Long Baseline Array of the National Radio Astronomy Observatory, have made a dramatic movie of a voracious, superdense neutron star repeatedly spitting out subatomic particles at nearly the speed of light.
A young star more than 2,000 light-years away in the constellation Cepheus may be belching out spheres of gas, ejecting them repeatedly — phenomena not predicted by current theories of how young stars shed matter.
The world’s two largest radio telescopes have combined to make detailed radar images of the cloud-shrouded surface of Venus and of a tiny asteroid that passed near the Earth.
A group of summer students making a long-shot astronomical gamble with the National Science Foundation’s Very Large Array have found the first radio emission ever detected from a brown dwarf.
A decision has been reached by the arbitrator in the dispute between COMSAT Corporation, now part of Lockheed-Martin Global Telecommunications, and Associated Universities, Inc regarding additional costs on the contract to design and construct the Green Bank Telescope.
The United States and Canada intend to collaborate on two of the most important radio astronomy projects of the new century — the Atacama Large Millimeter Array and the Expanded Very Large Array.
