NGC 3521

NGC 3521 is a flocculent[4] intermediate spiral galaxy located around 26[4] million light-years away from Earth in the constellation Leo. It has a morphological classification of SAB(rs)bc,[3] which indicates that it is a spiral galaxy with a trace of a bar structure (SAB), a weak inner ring (rs), and moderate to loosely wound arm structure (bc).[5] The bar structure is difficult to discern, both because it has a low ellipticity and the galaxy is at a high inclination[3] of 72.7° to the line of sight.[4] The relatively bright bulge is nearly 3/4 the size of the bar, which may indicate the former is quite massive.[3] The nucleus of this galaxy is classified as an HII LINER,[6] as there is an H II region at the core and the nucleus forms a low-ionization nuclear emission-line region.

gollark: Unless it can somehow precommit to torturing the simulations.
gollark: If it values suffering for its own sake it might as well do it anyway, but I don't think doing the torturing would advance other goals.
gollark: If you ~~*do* pull it~~ leave it contained, I don't think it has any actual reason to torture the simulation, since you can't verify if it's doing so or not and it would only be worth doing at all if it plans to try and coerce you/other people later.
gollark: You can hash it on each end or something to check.
gollark: Well, sure, but there are no relevant quantum effects and a properly working computer system can losslessly send things.
