Teamwork between gamma-ray and radio astronomers has produced a breakthrough in finding natural cosmic tools needed to make the first direct detections of the long-elusive gravitational waves predicted by Albert Einstein nearly a century ago. An orbiting gamma-ray telescope has pointed radio astronomers to specific locations in the sky where they can discover new millisecond pulsars. Millisecond pulsars, rapidly-spinning superdense neutron stars, can serve as extremely precise and stable...

The discovery of seventeen new millisecond pulsars was announced Dec. 5 at the American Astronomical Society Meeting by scientists from the Naval Research Laboratory (NRL) Space Science Division and a team of international researchers. The pulsars, discovered in radio searches of unidentified gamma-ray sources found with the Large Area Telescope (LAT) onboard NASA's Fermi Gamma-ray Space Telescope satellite represent a substantial increase in the number of known millisecond pulsars...

GREEN BANK, W.Va. (AP) - Eight new complex, carbon-containing molecules have been found in two interstellar clouds by an international research team using the Robert C. Byrd Green Bank Telescope. The team detected acetamide, cyclopropenone, propenal, propanal and ketenimine in Sagittarius B2 (N), while methyl-cyano-diacetylene, methyl-triacetylene and cyanoallene were found in the Taurus Molecular Cloud (TMC-1), the National Radio Astronomy Observatory announced Monday. Sagittarius B2 (N)...

NRAO -- Astronomers using the National Science Foundation's Robert C. Byrd Green Bank Telescope (GBT) have discovered a huge "superbubble" of hydrogen gas rising nearly 10,000 light-years above the plane of our Milky Way Galaxy. They believe the gas may be driven by supernova explosions and the intense stellar winds from an unseen cluster of young stars in one of our Galaxy's spiral arms. "This giant gas bubble contains about a million times more mass than the Sun and the energy powering its...

Berkeley -- Astronomers announced Thursday what may be the first discovery of a helical magnetic field in interstellar space, coiled like a snake around a gas cloud in the constellation of Orion. "You can think of this structure as a giant, magnetic Slinky wrapped around a long, finger-like interstellar cloud,'' said Timothy Robishaw, a graduate student in astronomy at the University of California, Berkeley. "The magnetic field lines are like stretched rubber bands; the tension squeezes the...

An international team of astronomers has looked at something very big -- a distant galaxy -- to study the behavior of things very small -- atoms and molecules -- to gain vital clues about the fundamental nature of our entire Universe. The team used the National Science Foundation's Robert C. Byrd Green Bank Telescope (GBT) to test whether the laws of nature have changed over vast spans of cosmic time. "The fundamental constants of physics are expected to remain fixed across space and time;...


Word of the Day
vermicular
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
