IC 405

IC 405 (also known as the Flaming Star Nebula, SH 2-229, or Caldwell 31) is an emission and reflection nebula[1] in the constellation Auriga, surrounding the bluish star AE Aurigae. It shines at magnitude +6.0. Its celestial coordinates are RA  05h 16.2m dec +34° 28′.[2] It surrounds the irregular variable star AE Aurigae and is located near the emission nebula IC 410, the open clusters M38 and M36, and the K-class star Iota Aurigae. The nebula measures approximately 37.0' x 19.0', and lies about 1,500 light-years away from Earth.[2] It is believed that the proper motion of the central star can be traced back to the Orion's Belt area.[2] The nebula is about 5 light-years across.[1]

gollark: It's ridiculous to complain that he doesn't know much about rocketry and stuff himself and (THE HORROR) hired competent people who do, and managed to improve the state of space travel a lot.
gollark: I'm not sure what you mean by "apartheid profiting", but generally that seems pretty stupid.
gollark: Unless they have a warrant, you can apparently just tell them to go away and they can't do anything except try and get one based on seeing TV through your windows or something.
gollark: But the enforcement of it is even weirder than that:- there are "TV detector vans". The BBC refuses to explain how they actually work in much detail. With modern TVs I don't think this is actually possible, and they probably can't detect iPlayer use, unless you're stupid enough to sign up with your postcode (they started requiring accounts some years ago).- enforcement is apparently done by some organization with almost no actual legal power (they can visit you and complain, but not *do* anything without a search warrant, which is hard to get)- so they make up for it by sending threatening and misleading letters to try and get people to pay money
gollark: - it funds the BBC, but you have to pay it if you watch *any* live TV, or watch BBC content online- it's per property, not per person, so if you have a license, and go somewhere without a license, and watch TV on some of your stuff, you are breaking the law (unless your thing is running entirely on battery power and not mains-connected?)- it costs about twice as much as online subscription service things- there are still black and white licenses which cost a third of the price
