Description

GUM 
The Vela Supernova Remnant is a large, complex about 800 light-years away remnant of a supernova explosion. The supernova that created the Vela Remnant occurred about 11,000 to 12,000 years ago in the southern constellation Vela.The Vela Supernova Remnant is one of the brightest and most studied supernova remnants in the sky, covering an area of about 8 degrees by 6 degrees on the sky, which is about 70 times the size of the full moon. It is also one of the nearest supernova remnants.The Vela Remnant is believed to have been created by a Type II supernova, which is the explosion of a massive star at the end of its life. The explosion expelled material out into the surrounding space, creating a shockwave that swept up and compressed interstellar gas and dust. This heated the gas and made it glow, producing the beautiful and complex structure we see today.The Vela Supernova Remnant has several interesting features, including a bright central region, known as the Vela pulsar wind nebula, which is powered by a rapidly rotating neutron star (pulsar) at its center. The pulsar emits a beam of radiation that sweeps across the sky like a lighthouse, producing a distinctive pattern of bright arcs and filaments in the nebula.
