This is the end of Kepler's supernova,the famous detonation that was found by Johannes Kepler in 1604.The red,green and blue color indicates low,medium and high energy X-ray detected with NASA's Chandra X -ray observatory,and the star field is form the digitized sky view.
As document in our press publish,a new analyze has used Chandra to identify what triggered this burst. It had already been established that the form of explosion was a so-called type is supernova,the thermonuclear explosion of the world.
The new Chandra psychoanalysis show the Kepler supernova was triggered by an action between a white dwarf and a red huge star. The essential information from Chandra was a disk-shaped structure near the center of remnant.The investigators translate this X-ray emission to be stimulated by the collision between supernova debris and disk-shaped substance that the huge star defeated before the explosion.
This composite image also shows an unusually huge and confusing concentration of iron on one side of the center of the star but not the other. The writer suppose that the effect of asymmetry might be the shadow in iron that was formed by companion star,which blocked the ejection of textile. Previously,theoretical wok has hinted this shadowing is possible for type la supernova remnants.
