A team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), of which the U.S. National Science Foundation National Radio Astronomy Observatory is a partner, has captured a massive stream of gas—one trillion miles, or .2 light years long—feeding the young triple-star system GW Orionis.

NSF NRAO radio observations help rule out a relativistic jet in rare stellar explosion
Astronomers studying a rare stellar explosion first spotted as a brief burst of X-rays used radio observations to help show that the dying star did not produce the powerful jet often associated with gamma-ray bursts.

Astronomers discover possible millisecond pulsar, challenging ideas about how many neutron stars lurk around the Milky Way’s central black hole
Astronomers from Breakthrough Listen have used the U.S. National Science Foundation National Radio Astronomy Observatory’s Green Bank Telescope (NSF GBT) to carry out one of the most sensitive pulsar searches ever aimed at the Milky Way’s Galactic Center.
The Galactic Center, home to the supermassive black hole Sagittarius A* and dense stellar populations, presents unique scientific opportunities and challenges for understanding stellar dynamics, extreme astrophysical environments, and tests of Einstein’s theory of General Relativity. In this research, recent Columbia University PhD graduate Karen Perez and collaborators conducted more than 20 hours of observations with the NSF GBT using the Breakthrough Listen Digital Backend, which enabled high-time and high-frequency resolution data products across a wide radio bandwidth. Of these observations, 11 hours were dedicated to the innermost 1.4 arcminutes of the Galactic Center, resulting in one of the deepest and most sensitive pulsar surveys ever performed toward this region.
These observations uncovered a promising candidate for a millisecond pulsar, with a rotation period of 8.19 milliseconds. If confirmed it would be the first such object found in the Galactic Center.
