Pismis 24-1
This genuinely stunning and somehow very 80s tableau from the emission nebula NGC 6357, in Scorpius, depicts two different big names from the interstellar whoâs who list. Pismis-1, the bright star in the cluster above, was once believed to be 200-300 solar masses, which would have been crazy huge. Itâs been since revised down to âjustâ a hundred solar masses, which still means we can expect its life cycle to include a supernova â possibly a hypernova â and then a black hole. Below, thereâs a bright young star blowing a stellar bubble inside the nebula. Its ultraviolet glow is part of what made it so hard for us to measure the mass of Pismis-1 and its fellows. Is it just me, or does it really look like this is painted on black velvet?
