A newly discovered galaxy has a dust trail more than 220,000 light years long.
The dust is planting the "seeds" of new stars.
Ming Sun of Michigan State University, who led the study says, "..it turns out that this is a giant wake of creation, not of destruction." Millions of stars have already been, or are in the process of being, born.
The galaxy, ESO 137-001 , is more than 220 million light years away and is headed towards a cluster of galaxies called Abell 3627.
