Serendipitous Discovery: Comet 28P/Neujmin Found in Archival Telescope Data

In the vast archive of images taken by Japan's Subaru Telescope for purposes entirely unrelated to comets, a team of astronomers found something no one had been looking for: a comet caught in the open, its nucleus bare and unguarded, drifting more than ten times the Earth's distance from the Sun.
