A Star’s Bow Wave

Seen in a false-coloured infra-red image on Astronomy Picture of the Day for 2/2/20 this shows the bow wave of runaway star Zeta Oph (centre, blue) travelling at 24 kilometres a second after its more massive companion star exploded and blew it out of the system.

Zeta Oph is 460 light years away and 65,000 times brighter than the Sun. Its true luminosity is obscured by dust though.
