Other astronomers soon discovered that the void contained a few galaxies. In 1987, J. Moody, Robert P. Kirshner, G. MacAlpine, and S. Gregory published their findings of eight galaxies in the void. M. Strauss and John Huchra announced the discovery of a further three galaxies in 1988, and Greg Aldering, G. Bothun, Robert P. Kirshner, and Ron Marzke announced the discovery of fifteen galaxies in 1989. By 1997, the Boötes void was known to contain 60 galaxies.
According to astronomer Greg Aldering, the scale of the void is such that "If the Milky Way had been in the center of the Boötes void, we wouldn't have known there were other galaxies until the 1960s. The Hercules Supercluster forms part of the near edge of the void. Using a rough estimate of about 1 galaxy every 10 million light-years (about 4 times further than the Andromeda Galaxy is from Earth), there should be approximately 2,000 galaxies in the Boötes void.
