What is the Boötes Void?
The Boötes Void is a huge, roughly spherical underdense region in the direction of the constellation Boötes. Redshift surveys found far fewer bright galaxies there than expected, making it one of the best-known nearby supervoids.
The void was found through redshifts
Kirshner, Oemler, Schechter, and Shectman reported a striking gap in galaxy redshifts in 1981, then confirmed a large low-density region with a wider survey in 1987.
The cosmic web surrounds it
Galaxies collect in sheets, walls, and threadlike filaments. Voids appear between those structures, like empty regions inside a foam of galaxies.
Interior labels are visible first
The explorer keeps all named labels on by default. The label button switches back to smart labels when the screen needs a quieter view.
This is a reconstruction-inspired map
The scale, center, sparse interior, and named targets are research grounded. The surrounding filaments and some depths are procedural to make the 3D structure readable.
