High mass star death

Stars like R136a1, the most massive star known, go hypernova, but fail to leave behind even a black hole. A supernova remnant on steroids would be what is left. Stars like VY Canis Majoris, which are less massive, also conclude their lives with a hypernova, but produce a black hole, which fires intense gamma ray bursts. We could be in the gun barrel of WR104, which has an axis which seems to point right towards us.
