type 1a ping

Thanks for the type 1a ping, longshadow.

Type 1a ...like the explosion of a hydrogen bomb approximately the size of the Earth but containing the mass of the Sun.

And only about 1 per millennium per galaxy of our size.

Last big one was probably the Crab Nebula (typeII) in 1054, recorded by Chinese as a 'guest star', but not in the West.

This one looks serious. Remember, don't bring a knife to a gunfight.
