Stellar Winds Flow Out From Zeta Ophiuchi. Button

Stellar winds flowing out from the giant star Zeta Ophiuchi are making ripples in the dust as it approaches, creating a bow shock seen as glowing gossamer threads, which, for this star, are only seen in infrared light. Zeta Ophiuchi is a young, large and hot star located around 370 light-years away. The fine filaments of dust surrounding the star glow primarily at shorter infrared wavelengths, rendered here in green. The area of the shock pops out dramatically at longer infrared wavelengths, creating the red highlights.
