PGC 42871 doesn't look like your typical galaxy. Those ghostly shells contain globular clusters of stars whose varying ages suggest that there have been multiple collisions with other galaxies in this one's past.
I love the way this strange galaxy looks like a giant silk organza flower, but as always what I like most in this Hubble image is the background, all those other tiny nebulae and galaxies and smudges of light. I know they're impossibly huge and impossibly cold and impossibly far away, but when I see these deep space images I always feel as though I've caught the universe dancing.
