What Astronomers are Gleaning from a Big Blast Called "Cow"
California Institute of Technology | 2019 Jan 10
Telescopes around the globe and in space raced to witness a dramatic stellar explosion
On June 16, 2018, a brilliant stellar explosion unlike any seen before went off in the skies, quickly capturing the attention of astronomers around the globe. First spotted by the ATLAS survey in Hawaii, the event was dubbed AT2018cow through a randomized naming system, and soon earned the nickname "Cow." Just three days after exploding, Cow had become 10 times brighter than a typical supernova—a powerful explosion that heralds the death of a massive star. ...
In the hours, days, and weeks after the event, telescopes on the ground and in space set their sights on Cow, witnessing a dramatic increase in brightness across the electromagnetic spectrum, from high-energy X-rays to low-energy radio waves. ...
