It's impossible to appreciate how vast the universe is, but this video will help
Earlier in January, NASA released a gigantic, incredibly sharp photo of the Andromeda Galaxy, taken by the Hubble space telescope. The galaxy has more than 100 billion stars, spread over 40,000 light years. It's tough to convey these huge numbers in a way that makes sense. But YouTube user daveachuk made the astounding video above that helps put them into perspective.
