Disadvantage Of A Panniculectomy

The blue star near the center of the image is called Zeta Ophiuchi and is less than 500 light-years away. If we saw in the wavelength optician would appear as a faint star and reddish, as surrounded by a huge invisible cloud of interstellar gas and dust. Quite different is its appearance when viewed from the mission WISE (Wide-field Infrared Survey Explorer) in the infrared. In this wavelength the gas and dust are highlighted and Zeta Ophiuchi is like a ship that sails the sea in great speed. Our star is really great, about twenty times more massive than the Sun and 65000 times as luminous as well.

Zeta Ophiuchi's past has been quite turbulent. Perhaps it was living in couples with a less massive star that came to the end of his short life, has exploded as a supernova, throwing around most of the material of which it was composed. Zeta Ophiuchi has been found free from the seriousness of the friend and was turned away at great speed from its birthplace. A kind of ship free to sail the sea of \u200b\u200bspace at high speed. It travels at 24 km per second (about 86000 km per hour). In his race is going through an area rich in gas and dust that will be invested by the stellar wind emitted by the star wandering. In particular, the ultraviolet radiation of the star heats the gas surrounding it and makes it look brighter in the infrared band.

Even more interesting is the arch structure prior to the movement of the star (it moves from bottom right to top left) corresponds to the front of the shock wave, known in the jargon " Bow Shock (shock arc), caused by the collision of the stellar wind and the gas that meets in the movement, strongly compressed. Something very similar to what happens in front of the bow of a ship while it high-speed plows the sea waves. All this is invisible to the human eye, but not in the eyes of infrared WISE.

Zeta Ophiuchi The cruise will not last very long. Given the considerable mass, his life will be short and not exceed four million years (nothing compared to the five billion years the Sun was still before him). The death will be far more violent than that of our star will become a quiet white dwarf, while Zeta Ophiuchi will explode like his old companion in a terrifying supernova. Probably his end in a violent way to compress gas and dust that surrounds and will kick off the formation of new stars. Universe nothing is wasted.
