Funny headline of the day:

Dwarfs found in colliding galaxies' wake - New Scientist

Okay so they are talking about dwarf galaxies, in particular, tidal dwarf galaxies (TGDs). TGDs are formed when two galaxies interact gravitationally. They form in long, tail-like structures but are so small and faint that only about a dozen had previously been observed. The more technically inclined reader may like to read the full article.

Still it sounds like something that was taken from a 'Have I Got News For You' guest publication :)
