Astronomers using the U.S. National Science Foundation Very Large Array (NSF VLA), together with the NASA James Webb Space Telescope and other observatories, have identified an enormous, galaxy-scale stream of super-heated gas erupting from the nearby galaxy VV 340a.

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.

Peering back in time, around 12 billion years, astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found the…

Astronomers using the U.S. National Science Foundation Very Large Array (NSF VLA) and the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered a rare protocluster that was exceptionally bright, all when the Universe was 11 billion years younger.

Astronomers have created a detailed forecast of where they expect to observe future stellar explosions in a nearby galaxy,…
