| Vela Supernova Remnants |
Approximately 11,000 years ago a star in the constellation of Vela located within the Gum Nebula, underwent a massive explosion. The power behind this particular explosion was so great that it left behind X-ray detectable shock waves that are still visible. When a star explodes, it emits enormous amounts of extremely hot gases that linger in the atmosphere for thousands of years to come. The explosion left behind filaments of glowing gas and a rotating stellar core called the Vela Pulsar. The remnants of the explosion extend up to 230 light years across, covering over 100 times the sky-area of the full Moon. The Vela supernova remnants are some of the closest to Earth.
