PSR J0538+2817 explained

PSR J0538+2817 is a pulsar situated in the constellation of Taurus. Discovered in 1996, it stirred interest from the fact that it is physically linked to the supernova remnant SNR G180.8–02.2.^{[1] [2]}

The characteristic age of PSR J0538+2817 gives an older estimate: 618,000 years. However, observation of the pulsar's proper motion gives a much younger result: 30,000 ± years, meaning that the pulsar must have begun rotating at a relatively slow pace, at 139 milliseconds.^[1]
