Around 11,000 years ago. A massive star explodes as a supernova, ejects its shell and ends up as a neutron star in the constellation Vela. The explosion was so bright that our ancestors could see it in the daytime sky. Only 2000 years earlier, a comet had struck the Earth, triggering a 1000-year cold period that forced our ancestors to settle down. The outer layers of the exploding star collided with the interstellar medium and triggered a shock wave that is still visible today as blue and red filaments. The Vela supernova appears in front of a huge red nebular structure, which probably dates back to a massive supernova explosion about 1 million years ago. At a distance of around 1000 light years, the Vela supernova is one of the closest supernovae to Earth. A wonderful object in the southern sky, which I exposed for about 12 hours.
