Analysis of two cosmic explosions indicates to astronomers that the pair, along with a puzzling blast from 2018, constitute a new type of event, with similarities to some supernovae and gamma-ray bursts, but also with significant differences.
Using VLA and Spitzer observations, astronomers are able to determine wind speeds on a brown dwarf for the first time. They believe the technique also could be used for exoplanets.
An international team of astronomers used ALMA and the VLA to create more than three hundred images of planet-forming disks around very young stars in the Orion Clouds. These images reveal new details about the birthplaces of planets and the earliest stages of star formation.
New technologies that enable new strategies are revitalizing the Search for Extraterrestrial Intelligence (SETI), by not only augmenting the traditional search for intelligently-generated radio signals but also allowing searches for other signs of life and technological activity.
NRAO and the SETI Institute will develop a new system to provide VLA data to an advanced signal processor that will seek to detect signs of extraterrestrial technologies.
Studies with the VLA indicate that roughly half of the massive black holes in dwarf galaxies are not in the centers of those galaxies. This gives astronomers new insights into the conditions in which similar black holes formed and grew in the early history of the Universe.
VLA image reveals a large-scale magnetic field extending far into a galaxy’s extended halo.
Astronomers have found the first example of a galaxy cluster where large numbers of stars are being born at its core. The discovery revealed new details of how supermassive black holes affect their host galaxies.
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.
