While analyzing NASA Hubble Space Telescope images of the Sagittarius dwarf irregular galaxy (SagDIG), an international team of astronomers led by Simone Marchi, Yazan Momany, and Luigi Bedin discovered 13 sucessive faint trails left by a tiny asteroid. The trails are seen as a series of reddish arcs on the right in this August 2003 Advanced Camera for Surveys image.
