The Eta Carina Nebula is famous for his name-giving massive double monster star system (more than 100 and 80 solar masses, 4-5 million-times more luminous than the sun), well known for his star forming regions and ultra-hot, massive/short living stars. However the region also lies in a neighbouring arm of our galaxy… the Carina-Sagitarius arm lays next to our Orion-Arm (in fact it is one arm closer to the center).. We are lying in the inner rim of the Orion arm… so the Eta-Carina nebula is sending us greetings directly from
the ‚other‘ side (see second post in comments).. and maybe soon a great Supernova explosion.
