Astronomers have discovered the first aurora ever seen in an object beyond our Solar System. The aurora, similar to the famous "Northern Lights" on Earth, is 10,000 times more powerful than any previously seen.
Thanks to the extraordinary sensitivity of the Karl G Jansky Very Large Array (VLA), astronomers have detected what they believe is the long-sought radio emission coming from a supermassive black hole at the center of one of our closest neighboring galaxies.
Astronomers using the National Science Foundation's Very Large Array (VLA) have found a long-sought 'missing link' between supernova explosions that generate gamma-ray bursts (GRBs) and those that don't. The scientists found that a stellar explosion seen in 2012 has many characteristics expected of one that generates a powerful burst of gamma rays, yet no such burst occurred.
