The unique shape of the NGC23509 nebula gave it the name “Thor’s Helmet”, due to the fact it is similar in shape to the legendary helmet of the Norse god. The nebula is 11,000 light years away from us, and it’s bubble shape was created due to materials getting pushed to the center of the planet by the winds constantly blowing.
