A recent measurement of the proper motion of PSR J0908-4913 shows that it isa fast moving object at a distance of some 3 kpc. Here we present evidence thatthe pulsar is located at the edge of a previously unknown, filled-centresupernova remnant, G270.4-1.0. The velocity vector of the pulsar pointsdirectly away from the centre of the remnant. The putative association of thepulsar with SNR G270.4-1.0 implies the pulsar is ~12kyr old, significantly lessthan its characteristic age of 110kyr. We show that the rotation axis of thepulsar points in the direction of the proper motion. Rotation measure anddispersion measure variations are seen over time, likely indicating the pulsaris passing behind a filament of the remnant.
