Zeta Ophiuchi bow shock. Infrared image from NASA's Spitzer Space Telescope (SST) of the bow shock in the interstellar medium caused by stellar winds from the fast-moving star Zeta Ophiuchi. This star is around 370 light years from Earth in the constellation of Ophiuchus. Many times hotter, brighter and more massive than our Sun, it is travelling at about 24 kilometres per second. The fine filaments of dust surrounding the star glow primarily at shorter infrared wavelengths (green). The bow shock (about half a light year from the star) is seen at longer infrared wavelengths (red). The shortest wavelengths are in blue. Image published in 2012.
