NASA announced the oldest super star debris photos

On October 26, 2011, NASA published a piece by spitzer space telescope and the wide-area infrared detector in the synthesis of shooting a supernova remnants RCW86 pictures, combination of NASA's spitzer space telescope infrared measuring probe and wide Angle of infrared image and prior NASA's chandra X-ray observatory and the European space agency XMM Newton astronomical telescope X-ray data.retro jordan shoes, RCW86 is astronomers recognized outbreak of human stars or supernova first recorded.

China's the HouHanShu · chinese-speaking volunteers day "account:" flat in October in two compounds hai (A.D. December 7, 185), KeXing out in the south." In the 1960 s, scientists believe, this text is the earliest record of human of supernova. Western astronomers call the supernova Numbers for "SN185". Later, the scientists confirmed, "RCW86" is this supernova debris, located at 8000 light years outside.

According to the current understanding, the supernova outbreak is a massive star "sudden death".jordan shoes store, For massive stars, such as equivalent to the quality of the mass of the sun 8 ~ 20 times the stars, because the quality is big, in the later stages of the evolution of them, the nuclear and star shell separated completely, often with a super size of the big bang. This is a supernova explosion. Has proved, in 1572 and 1604, nova belong to the supernova. In the Milky Way galaxy in the river and many have now been observed supernovae, for a total of hundreds of stars. But in the past, people observed with the naked eye and recorded supernova, but only six stars. Stars starting from the center cooling, it does not have enough quantity of heat balance gravity center, on the structure will make the whole astral to imbalance center collapse, causing external cooling and the level of red hot, if star is big enough, these planes will happen severe explosion, producing a supernova. High-mass stars exploded photometric running to the sun of the luminosity tens of billions of times, which is equivalent to the total luminosity of the galaxy. The results of the exploded star: (1) stars as a group to the disintegration of the spread of the expansion of the mixture of gas and dust, and finally to diffuse interstellar material, end of evolution stars. (2) for the outer collapse to the expansion of the nebula, the center left behind for a physical collapse of high density objects, thus enter the evolution of stars and end the late stage. Chinese ancient astronomers observed in 1054 the outbreak of the supernova (this supernova and be named China international supernova). In a galaxy, the supernova is a rare astronomical phenomenae, but in galaxies in the world, but every year to dozens of observed. jordan shoes,February 23, 1987, A Canadian astronomers in the large Magellanic cloud, found A supernova, this is the first star since 1604 with the naked eye can see supernova, the supernova was named "1987 A".
