Astronomers using the U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO) instruments, the U.S. National Science Foundation Very Large Array (NSF VLA) and the Atacama Large Millimeter/submillimeter Array (ALMA), have revealed a dense cocoon of gas around one of the most extreme cosmic explosions ever seen, showing that a ravenous black hole ripped apart a massive star and then lit up its surroundings with powerful X-rays.

NSF NRAO Radio Telescopes Help Reveal Cloud-9, a Starless Dark-Matter “Failed Galaxy” Near M94
Astronomers using a powerful combination of radio and optical telescopes have confirmed that a peculiar gas cloud near the spiral galaxy M94 is a “failed” galaxy; a dark-matter-dominated halo filled with gas but entirely lacking stars.
Astronomers & Engineers Use a Grid of Computers at a National Scale to Study the Universe 300 Times Faster
Looking for a more efficient way to process a particularly large VLA data set, to produce one of the deepest radio images of the Hubble Ultra Deep Field (HUDF), made famous by the Hubble Telescope, NRAO staff decided to try a different approach.
