Crab Nebula: In the year 1054 Arab, Chinese and Japanese astronomers recorded a new star (Nova), which was for a few weeks so bright that it could be seen during the day. We know today that this was a Super Nova explosion, where a massive star collapsed into a fast spinning neutron star, which is now called the Crab Pulsar.
The image shows the remnants of this event, which are also called the Crab Nebula. The debris is still moving with a velocity of 1500 km per sec apart and covers now a region witha diameter of 11 LY.

The image was taken at the observatory of IAS at Hakos Farm in Namibia.
