Yes, there is a Vela Nebula (also known as the Vela Supernova Remnant) in which the Vela Pulsar is located. The Vela Nebula is a large and relatively nearby supernova remnant in the southern sky, situated in the constellation Vela. It is the result of a supernova explosion that occurred approximately 11,000 to 12,300 years ago.
The Vela Pulsar, also referred to as PSR B0833-45 or the Vela pulsar, is a highly-magnetized neutron star that lies within the Vela Nebula. It is a rapidly rotating pulsar, emitting regular pulses of electromagnetic radiation as it spins. The Vela Pulsar is a significant source of X-rays and gamma rays, and its emissions interact with the surrounding nebula, producing various features and structures within the Vela Nebula.
