Astronomers using the National Science Foundation’s Very Large Array radio telescope are taking advantage of a once-in-a-lifetime opportunity to watch an old star suddenly stir back into new activity after coming to the end of its normal life.

Astronomers using the National Science Foundation’s Very Long Baseline Array have measured the motion across the sky of a galaxy nearly two and a half million light-years from Earth.

Astronomers at Sweet Briar College and the Naval Research Laboratory have detected a powerful new bursting radio source whose unique properties suggest the discovery of a new class of astronomical objects.

Riccardo Giacconi, very recently retired President of Associated Universities, Inc. (AUI), will be awarded the National Medal of Science by President George W. Bush on March 14, according to the White House.

A giant flash of energy from a supermagnetic neutron star thousands of light-years from Earth may shed a whole new light on scientists’ understanding of such mysterious magnetars and of gamma-ray bursts.

Radio telescopes, including major facilities of the National Science Foundation’s National Radio Astronomy Observatory, have provided data needed to measure the winds encountered by the Huygens spacecraft as it descended through the atmosphere of Saturn’s moon Titan last month — measurements feared lost because of a communication error between Huygens and its mother ship Cassini.
