PSR B0950+08 is a young pulsar that may have come from a supernova that occurred in the Constellation of Leo 1.8 million years ago. Off-pulse emissions from the young pulsar were detected by the Expanded Long Wavelength Array, suggesting the presence of a pulsar wind nebula around it.

PSR B0950+08 was fourth among the initial radio pulsars discovered in 1968. It completes rotation every 0.253 seconds.

It was postulated in 2002 to be related to the Antlia Supernova Remnant, but a 2021 study estimates the age of the remnant to be less than 100,000 years.
