Quoting the Hubble Telescope website:
This pair of galaxies, NGC 4676, also known as “The Mice” for their tails of stars and gas, have collided and will eventually merge into a single galaxy. Streams of material have been tugged out of the galaxies by the force of gravity, triggering new starbirth.
When will be discovered a galaxy called Optimiced, then? ;-)
(I guess, I’ll have first to discover it…:-)
