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 Detect Powerful Bursting Radio Source
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.
Mysterious Magnetar Yielding Secrets to VLA
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 ‘Save the Day’
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.
Star Cluster Buzzing with Pulsars
A dense globular star cluster near the center of our Milky Way Galaxy holds a buzzing beehive of rapidly-spinning millisecond pulsars, according to astronomers who discovered 21 new pulsars in the cluster using the National Science Foundation’s 100-meter Green Bank Telescope in West Virginia.
Blazar Jets Push Closer to Cosmic Speed Limit
Astronomers using the National Science Foundation’s Very Long Baseline Array have discovered jets of plasma blasted from the cores of distant galaxies at speeds within one-tenth of one percent of the speed of light, placing these plasma jets among the fastest objects yet seen in the Universe.
