W50 (nebula)
W50 or SNR G039.7-02.0, once referred to as the Manatee Nebula,[1] is a Supernova remnant located in the constellation Aquila, about 18,000 light years away. In its centre lies the micro-quasar SS 433, whose jets are distorting the remnant's shell. Most likely W50 and SS 433 are related objects, remnants from a supernova which occurred about 20,000 years ago.[1] [2]

gollark: But you do need dates fairly often, and this makes it *consistent* between implementations.
gollark: For example, as well as the time-duration-type thing ("5y2mo3w" etc) it actually supports DD/MM/YYYY as well as some weird backward thing because it uses an external library for it too.
gollark: And even then it still has some weirdness.
gollark: Datetimes are very hard. AutoBotRobot has to do a bunch of stuff to make it do even roughly what people expect.
gollark: Although it does rely on JSON for encoding queries and sending results back, I guess.
