Astronomers using the National Science Foundation’s newly commissioned Green Bank Telescope have detected remarkably faint radio signals from an 820 year-old pulsar, making it the youngest radio-emitting pulsar known.
Age Discrepancy Throws Pulsar Theories into Turmoil
Astronomers using the National Science Foundation’s Very Large Array radio telescope have found a pulsar — a spinning, superdense neutron star — that apparently is considerably younger than previously thought.
GBT, VLA Team Up to Produce New Image of Orion Nebula
Combining the best features of the National Science Foundation’s new Green Bank Telescope in West Virginia with those of the NSF’s Very Large Array in New Mexico, astronomers have produced a vastly improved radio image of the Orion Nebula and developed a valuable new technique for studying star formation and other astrophysical processes.
Stars Need a ‘Kick’ to Get Started
Star formation is a longer process than previously thought, and is heavily dependent on outside events, such as supernova explosions, to trigger it, a team of astronomers has concluded. The scientists reached their conclusions after making a detailed study of a number of the dark gas clouds in which new stars are formed.
Newly Commissioned GBT Bags New Pulsars
Astronomers using the National Science Foundation’s newly commissioned Robert C. Byrd Green Bank Telescope (GBT) have discovered a windfall of three previously undetected millisecond pulsars in a dense cluster of stars in the Milky Way Galaxy.
Star Caught in the Act of Planetary Nebula Formation
A team of astronomers using the National Science Foundation’s Very Large Array radio telescope has caught an old star during the very brief period of its transformation into a planetary nebula, a shining bubble of glowing gas with a hot remnant star at its center.
