The shock wave from a bright supernova that exploded in 1987 has now reached the edge of a cavity around the dead star, reveal new observations with the Hubble Space Telescope and the Chandra X-ray Observatory.
As intense heat from the shock wave continues to spread, it will illuminate the dense gas blown off by the detonating star, which was originally about 20 times more massive than our Sun."
