The Vela Supernova Remnant (also known as Vela-SNR) is a remnant of a supernova explosion that took place about 11,000 to 12,000 years ago. It is located in the southern hemisphere of the sky in the constellation Vela (Sail of the Ship).
The Vela-SN remnant covers an area of about 8 degrees in the sky, which is about 16 times the size of the full moon. It consists of various components, including a series of filaments, shock waves and pulsar wind nebulae.
The supernova that produced the Vela SN remnant was one of the closest known supernovae to Earth, leaving behind a large amount of matter that is expanding at high speed. The shock wave from the explosion collides with the interstellar medium, creating characteristic shock fronts and filaments.
At the center of the Vela-SN remnant is the Vela pulsar, a high-energy neutron star that spins extremely fast and emits regular pulses of electromagnetic radiation. The pulsar has an influence on the surrounding matter and produces the pulsar wind nebula, which is visible as a bright, high-energy structure.
