Mini Milky Ways Pack a Big Punch

Astronomers looking at galaxies in the universe’s distant past found nine young, compact galaxies, each weighing in at 200 billion times the mass of our Sun. Each compact galaxy is only 5000 light years across which is a fraction of our own grown up Milky Way but contains roughly the same number of stars.

A planet in a compact galaxy would see 200 times more stars in the sky than you do from Earth. Get the full story from HubbleSite.org.
