NASA's WISE mission, or Wide-field Infrared Survey Explorer, has spotted the bow shock of a runaway star.  Zeta Ophiuchi -- Runaway Star Plowing Through Space DustBow shocks like this are formed as a star hurtles through space at high speed, pushing gas and dust out of it's way and heating it in the process.  If heated enough, the gas starts to glow in infra-red, and can be seen by our instruments.
