Ray space telescope NASA Chandra, began to study the outstanding traces of an antique supernova explosion, which he observed by Io Gunn Kepler .
For the first time, a mention about this supernova are dated 1604. When the night sky is a new star in the place where previously there was none. This event recorded many of the astronomers of the time, including Johannes Kepler.
After several centuries, the "garbage" that was left after the explosion of this supernova was studied Space Telescope, Chandra. This astronomical instrument, which even the ancient astronomers could not have dreamed, in detail may help astronomers understand the present in the explosion of a supernova, the effects of which have been recorded in 1604.
Initial analysis of the supernova remnant has already identified what he supernova had not only much harder than previously thought, but also occurred at a greater distance than assumed astronomers in 1604.
According to the previous analysis, which was performed by the images revealed that the supernova belongs to the category Ia, and the remains of the star after the explosion, "explosive dust" are asymmetrical shape. Explosions of supernova, which are classified as Ia, occur when a white dwarf star begins to gain weight rapidly, pulling material from the surface of the star-neighbor and because of merging with it. After that, the star becomes very unstable and it is that of a major thermonuclear explosion.
Unlike other scientists previously observed supernova remnants, which belonged to the class Ia supernova remnants, the flash which was incorporated in 1604, has an asymmetric shape. A similar phenomenon can be explained by the fact that white dwarf itself, as well as star-neighbor moved with too much speed, which was the cause of creating a kind of shock. Similarly uneven distribution of the remains of a supernova could have been caused by the presence of dense interstellar gas clouds that were in the area of the explosion of a supernova.
According to recent observations, which were carried out by the Space Telescope Chandra, scientists have established the presence of a large amount of iron present in the remains of a supernova. This may mean that in zryv, was much more powerful than other supernovae even in Class Ia.
