VLA observations revealed that cosmic rays can play an important role in driving winds that rob galaxies of the gas needed to form new stars. This mechanism may be an important factor in galactic evolution, particularly at earlier times in the history of the universe.
Astronomers using data from the VLA Sky Survey have discovered one of the youngest known neutron stars — possibly as young as only 14 years. The dense remnant of a supernova explosion was revealed when bright radio emission powered by the pulsar’s powerful magnetic field emerged from behind a thick shell of debris from the explosion.
Seven new scientific results from the Atacama Large Millimeter/submillimeter Array (ALMA), the Very Large Array (VLA), and the Very Large Array Sky Survey (VLASS) will be revealed at multiple press conferences during the 240th meeting of the American Astronomical Society (AAS) between June 13-15, 2022 in Pasadena, California.
A highly active repeating Fast Radio Burst is raising new questions about the nature of such objects, and also raising doubts about their usefulness as cosmic yardsticks.
Astronomers have discovered more than 5,000 planets orbiting other stars. We now know that most stars have orbiting planets…
The formation of massive stars and planets. The deaths of stars and galaxies. The extreme and violent behaviors of black hole jets and quasars. An up-close and personal radar view of the Moon. These mysteries and more were unraveled in 2021 by radio astronomers leveraging the scientific and technological power of National Radio Astronomy Observatory (NRAO) facilities.
Astronomers used the VLA to trace a corkscrew-shaped magnetic field in a powerful jet of material ejected from the core of a massive galaxy farther away from the central galaxy’s central black hole than ever seen before. The new images provide clues that will help understand the mechanics of such jets, which are seen throughout the Universe.
A system designed to provide streaming data from the VLA to SETI Institute equipment to search for radio transmissions possibly generated by extraterrestrial civilizations has successfully completed its first test.
The National Radio Astronomy Observatory congratulates four astronomers who earned Breakthrough Prize Foundation awards for their outstanding research on a collision between two neutron stars. Their work made extensive use of the VLA and VLBA.
The Very Large Array Sky Survey gave astronomers the first clue that ultimately revealed a dramatic story — the remnant of a star that exploded long ago had plunged into the core of its companion star causing it, too, to explode as a supernova.
