'''PSR B0950+08''' is a young [[pulsar]] that may have come from a [[supernova]] that occurred in the [[Constellation]] of [[Leo (constellation)|Leo]] 1.8 million years ago. The large and old [[supernova remnant|remnant]] of this supernova, located in the constellation of [[Antlia]], may be the nearest besides the [[Local Bubble]], and the supernova would have been as bright as the moon. Off-pulse emissions from the young pulsar were detected by the [[Long Wavelength Array|Expanded Long Wavelength Array]], suggesting the presence of a pulsar wind nebula around it.<ref name="Ruan2020"/>

PSR B0950+08 was fourth among the initial [[radio pulsars]] discovered in 1968.<ref name="Zharikov2002"/>
