The Kappa Cassiopeiae star, or the HD 2905, taken from NASA's Spitzer Space Telescope (SST), released on Feb. 22, 2014. Kappa Cassiopeiae is a massive, hot supergiant moving at around 2.5 million mph relative to its neighbors (1,100 km per second). The surrounding red streaks of material in its path are called bow shocks, and they can often be seen in front of the fastest, most massive stars in the galaxy.
