A Galaxy Just Appeared Out of Nowhere

While scanning the skies, astronomers were absolutely shocked when they discovered something they’d never seen before. That something was a huge galaxy orbiting our own. Never seen before, it was quite unexpected to discover a large dwarf galaxy where we previously hadn’t seen one.

Now known as the ‘Crater 2’, this galaxy didn’t actually just materialize into orbit around ours…it’s been there the entire time. How did we miss it though? It’s a galaxy, the 4th biggest near us to be exact. Regardless or it’s ranking in size…it’s a freaking galaxy! The biggest things in the universe. How did scientists and astronomers alike miss such a blatantly large thing?

Well, it has to do with light. Crater 2, while humongous and very close to us, is one of the darkest galaxies that we’ve ever observed. Pair that with the fact that it’s also surrounded by a handful of much brighter galaxies, and it makes a bit more sense that we missed it.
