The Crescent Nebula looks like supernova has gone off, creating the tendrilly patterns of material emitted or gathered up at the front of supersonic shock waves. The Crescent Nebula is not a supernova remnant, but contains a Wolf Rayet star at its heart..

The star may even be following up with more either periodically or even continuously. In this short post, I merely speculate because I will have to learn more myself….
