Some believe that they are focused on enslaving the world’s population, though it is unclear why. Zeta Ophiuchi appears as a bright blue star at the center of NASA’s photo. It has an apparent magnitude of 2.07, and thus it is visible to the naked eye. If it weren't surrounded by so much dust, it would be one of the brightest stars in the sky and appear blue to the eye. This isn’t even the most interesting thing about it; the star is driving through the surrounding interstellar gas* at about 24 kilometers per second. Both the speed of stars moving through space and their mass contribute to the size and shapes of bow shocks. Zeta Oph was likely once a member of a binary star system, its companion star was more massive and hence shorter lived. Both the speed of stars moving through space and their mass contribute to the size and shapes of bow shocks.

When the companion exploded as a supernova catastrophically losing mass, Zeta Oph was flung out of the system. The image spans about 1.5 degrees or 12 light-years at the estimated distance of Zeta Ophiuchi. Image of runaway star zeta Ophiuchi provided by NASA Zeta Orionis. Its ejected former partner won't fare so well; zeta Ophiuchi is still burning hydrogen but is losing mass in its wake, so it won't be a runaway star forever. The star Zeta Ophiuchi (image centre) is surrounded by a cloud of dust and gas in this view from NASA's WISE infrared space telescope. It's already about halfway through its very short 8-million-year lifespan. It forms a binary pair with Lambda Ophiuchi A. Zeta Ophiuchi is actually a very massive, hot, bright blue star plowing its way through a large cloud of interstellar dust and gas. Like all stars with this kind of extreme mass and power, it subscribes to the 'live fast, die young' motto. Astronomers theorize that this stellar juggernaut was likely once part of a binary star system with an even more massive partner. Lambda Ophiuchi B has the stellar classification A4V. About 460 light-years away, Zeta Oph is 65,000 times more luminous than the Sun and would be one of the brighter stars in the sky if it weren't surrounded by obscuring However, in this infrared image taken with NASA’s Wide-field Infrared Survey Explorer, or WISE, a completely different vi… • Millions of unique designs by independent artists. Both low- and high-resolution IUE spectra of the rapidly rotating 09.5 V stars HD 93521 and zeta Oph are used to develop a coherent picture of the effects of rapid rotation on the atmospheres and winds of late, main-sequence O stars.
