Radio telescope observations have made it possible for astronomers to use mergers of neutron-star pairs as a valuable new tool for measuring the Universe’s expansion.
For decades astronomers have dreamed of seeing a black hole. That dream may soon become a reality.
A dusty, doughnut-shaped feature long thought to be an essential part of the “engines” at the cores of active galaxies, is seen for the first time in one of the most powerful galaxies in the Universe.
VLA image shows the trail of a speeding pulsar pointing directly back at the center of the debris shell from the supernova explosion that created it.
Astronomers have studied a perplexing cosmic blast with a worldwide collection of telescopes, including ALMA and the VLA, but still are not sure exactly what it is.
Comparing data from new, ongoing sky survey to data from previous observations reveals probable gamma ray burst that directed no gamma rays toward Earth.
The VLA’s discovery of a jet of material launched from a highly-magnetic neutron star has forced rethinking a longstanding theory.
Astronomers have used the VLA to detect a possible planetary-mass object with a surprisingly powerful magnetic field some 20 light-years from Earth. It can help scientists better understand magnetic processes on stars and planets.
The track of an elusive, energetic neutrino points to a distant galaxy as its source and VLA observations suggest high-energy particles may be generated in superfast jets of material near the galaxy’s core.
VLA observations have pointed to the most likely explanation for the phenomena that followed the violent collision of a pair of neutron stars in a galaxy 130 million light-years from Earth.
