Boötes Void: Universe’s Loneliest Region

The Boötes Void is an enormous, nearly empty region of space about 330 million light-years in diameter located in the direction of the Boötes constellation. Astronomers discovered the vast cosmic void in 1981 while mapping the large-scale structure of the universe. The region has significantly fewer galaxies than typical areas of space. Scientists note that if the Milky Way had been located at its center, humanity might not have discovered other galaxies until the 1960s.
