Faster than a speeding bullet? More like faster than a supernova-propelled, hot blue supergiant!
In this stunning image fresh from NASA's Wide-field Infrared Survey Explorer (WISE), a bright star can be seen in the center of the shot. This star is called Zeta Ophiuchi, located 458 light-years from Earth (and 20-times the mass of our sun) in the constellation of Ophiuchus (yes, that Ophiuchus).
Why is Zeta Ophiuchi so special? It's a runaway star, traveling at a breakneck speed of 87,000 kilometers per hour (or 24 kilometers per second). And how did it get accelerated to that speed? After all, stars don't just careen around the galaxy - eventually being ejected from the Milky Way all together - for no reason.
