supernova remnant radio source A gaseous nebula, the expanding shell ejected by a supernova, and deriving its energy (at least in some cases) from the conversion by the remanent neutron star of its rotational energy into a stream of high-energy particles being continually accelerated in the SNR. About 100 SNRs are known in our Galaxy. Supernova remnants are usually powerful radio sources.

W51 supernova remnant A radio source, a supernova remnant. PSR 1919+14 lies within its radio contours.
