There’s a Giant Void in Space with Almost Nothing in It

The Boötes Void is one of the strangest places in the universe—a vast region 250 to 330 million light-years across that’s almost completely empty. While a typical part of space is packed with galaxies, this void has barely anything. It’s so large that if the Milky Way were at its center, we wouldn’t have known there were other galaxies until the 1960s.
