Supernova SN 1006
In 1006, the appearance of a "new" star in the sky was documented by observers in China, Japan, Korea, Arabian countries, and Europa. It was a relatively close supernova, 3,500 light years wide, which reached the brightness of a quarter of the Moon. Up until the present time, the explosion cloud has extended to 35 light years and is an intensiv X-ray emitter. The ROSAT PSPC colour image clearly shows a harder spectrum (blue) at the two spherical caps in the northeast and southwest than in the remaining region, especially that of the inner part (reddish). Spectroscopic measurements with the X-ray satellite ASCA indicate that the X-ray emission from the inner part comes from a few million degree hot plasma, whereas that from the spherical caps has a non-thermal origin. If this is synchrotron ratiation, then electrons with energies up to 50 billion electron volts are needed to be accelerated in the "blue" regions through the impact of the explosion shock wave. With it we see perhaps in SN 1006 for the first time the acceleration regions of the cosmic radiation.
