A Star Seen Halfway Across the Universe

16 July 2018

Nine billion light years away, the blue supergiant Icarus is the most distant star ever seen. In 2016 it briefly flared to 2000 times its original brightness as its light was magnified fortuitously by the gravity of a passing star in a foreground galaxy. The result, published in the journal Nature Astronomy, was carried out by an international team of astronomers that includes NOAO astronomer Tom Matheson.
