Object information |
Seen towards the constellation Taurus this object covers nearly 3 degrees (6 full moons!!) on the sky corresponding to a width of 150 light-years, estimated distance is 3,000 light-years. This supernova remnant has an apparent age of about 100,000 years - meaning light from the massive stellar explosion first reached Earth 100,000 years ago - but this expanding remnant is not the only aftermath. The cosmic catastrophe also left behind a spinning neutron star or pulsar, all that remains of the original star's core. |

Comments |
This is the best part of a three frame mosaic gone bad (see the whole picture below). Mars is just too close and makes light streaks on the picture. Its easy to see on the inverted picture the lightbeam radiating from the lower left corner. |
