Hyperactive galaxy NGC 7673
cosmosscience:

Ring around the galaxy.
Description: A small satellite galaxy, seen as an orange blob, gets stretched into a ribbon of stars as it’s pulled apart by a larger spiral galaxy in an artist’s impression.
Previously, astronomers had used detailed computer models to show how tidal streams and other signatures of galaxy digestion might look around spiral galaxies. The new survey has shown that all the predicted features actually exist in the universe—strong evidence that current models of galaxy evolution are on the right track, the study authors say.
