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.
Young Star Burping Spheres of Gas
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.
First Radio Emission Seen from a Brown Dwarf
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.
VLA’s Sharpened Vision Sees Still-forming Star
Using a new observing capability of the National Science Foundation’s Very Large Array radio telescope, astronomers have discovered a solar-system-sized disk of gas and dust feeding material onto a young star with 8 to 10 times the mass of the Sun.
Young Galaxy is Surrounded by Star Fuel
Looking more than 12 billion years into the past, the scientists found that the young galaxy experiencing a burst of star formation was surrounded by enough cold molecular gas to make 100 billion suns.
Pulsars Are Lying About Their Ages
Pulsars, those spinning, superdense neutron stars that send powerful lighthouse beams of radio waves and light flashing through the Universe, have been lying about their ages.
