A cosmic measurement technique independent of all others adds strong evidence pointing to a problem with the current theoretical model describing the composition and evolution of the Universe.
Some young, still-forming stars are surrounded by regions of complex organic molecules called “hot corinos.” In some pairs of young stars forming together as binary pairs, astronomers found a hot corino around one, but not the other. Guessing that the unseen one might be obscured by dust, researchers studied such a pair with the VLA at radio wavelengths that readily pass through dust, and found the other one.
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.
Galaxy DLA0817g, nicknamed the Wolfe Disk after the late astronomer Arthur M. Wolfe, is the most distant rotating disk galaxy ever observed.
What does an active black hole look like? It depends on your point of view.
ALMA is the first telescope to measure the gases originating directly from the nucleus of an object that travelled to us from another planetary system.
The Central Development Laboratory is often hidden behind the headlines of scientific discovery, but it’s research and development creates the tools radio astronomers use every day.
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.
The Event Horizon Telescope has observed the finest detail ever seen in a jet produced by a supermassive black hole.
Thankful Cromartie, a NRAO Grote Reber doctoral fellow at the University of Virginia’s Department of Astronomy, has received an Einstein Fellowship under the prestigious NASA Hubble Fellowship Program (NHFP).
