I am a native in this world And think in it as a native thinks

Astronomy Tuesday

This is an infrared, false color image that lets you see the shock wave created by the bright blue star in the middle, Zeta Oph. The star is moving at 24 kilometers per second, pushing the interstellar gases in a wave in front of it. It's probably an orphan, originally part of a binary star system. When its companion exploded as a supernova, Zeta Oph was flung out of the system, and it's still flying.
