Flying Star Zeta Ophiuchi - Runaway Star Zeta Ophiuchi - The blue star near the center of the image is Zeta Ophiuchi, a very massive star moving at 24 km per second. It is a “” fleeing star”, a star ejected by the explosion of his companion star. In this infrared image obtained by the WISE (Wide - field Infrared Survey Explorer) satellite, the interstellar dust traversed by the star appears, as well as an arc-shaped shock wave caused by the powerful stellar winds that the star breaks. The blue star near the center of this image is Zeta Ophiuchi. When seen in visible light it appears as a relatively dim red star surrounded by other dim stars and no dust. However, in this infrared image taken with Nasa's Wide - field Infrared Survey Explorer, or WISE, a completely different view emerges. Zeta Ophiuchi is actually a very massive, hot, bright blue star plowing its way through a large cloud of interstellar dust and gas. Astronomers theorize that this stellar juggernaut was likely once part of a binary star system with an even more massive partner. It's believed that when the partner exploded as a supernova, blasting away most of its mass, Zeta Ophiuchi was suddenly freed from its partner's pull and shot away like a bullet moving 24 kilometers per second (54,000 miles per hour). Zeta Ophiuchi is about 20 times more massive and 65,000 times more luminous than the sun. If it werenn't surrounded by so much dust, it would be one of the brightest stars in the sky and appear blue to the eye. Like all stars with this kind of extreme mass and power, it subscribes to the 'live fast, die young' motto. It's already about halfway through its very short 8 - million - year lifespan. In comparison, the sun is roughly halfway through its 10 - billion - year lifespan. While the sun will eventually become a quiet white dwarf, Zeta Ophiuchi, like its ex - partner, will ultimately die in a massive explosion called a supernova. Perhaps t
