About the Local Void

The light we see from it set out 0.0748 billion years ago, when the universe was 13.7 billion years old (redshift 0.005197).

The map lists it as a cosmic void and shows it at the scale of the large-scale universe, drawn on the supergalactic plane.

Its distance or nature is debated, and the map shows one published value.

The empty region next to the Local Group, at least 45 Mpc across (possibly 150–300). Its push and Virgo's pull explain about half our motion relative to the CMB.

From Wikipedia

The Local Void is a vast, empty region of space, lying adjacent to the Local Group. Discovered by Brent Tully and Rick Fisher in 1987, the Local Void is now known to be composed of three separate sectors, separated by bridges of "wispy filaments".
