It was discovered in 1981 by astronomer Robert Kirshner as part of a survey of galactic redshift to map the large-scale structure of the universe. Its center is located 700 million light-years from Earth, at right ascension 14h 50m and declination 46°.

The Hercules Superclusters are part of the near edge of the void.

Formation

The existence of the Boötes Void does not appear to conflict with the Lambda-cold dark matter (ΛCDM) model of cosmological evolution. It is hypothesized that the Boötes Void formed through the coalescence of smaller voids. This process may explain the presence of a limited number of galaxies within a roughly cylindrical region extending through the center of the void.
