Actually, I made this gif from a newer version of their animation, so it's more like 20 years.
I've used this gif to motivate a fun activity in astro 101 classes: find mass of SMBH. Only need to tell them distance to gal cntr.
...and the scale of the image, I think? (unless there's some sorcery involved...)
is it considered rude to be throwing stars around like that?
I think about a parsec, maybe a bit less. It's .5 arcsec on a side at a distance of about 25000 light years.
Some great discussion of this at @TitaniumPhysics podcast, with @bnprime, @AstroKatie, @rebeccawatson, @HannaloreJoy …http://titaniumphysicists.brachiolopemedia.com/2016/12/12/episode-69-super-hyper-fire-hose-bucket-challenge/ …
The black hole at the center of the Milky Way -- the ☆ in the center -- is called Sagittarius A*. It is about 4 million solar masses.
When I used Keck NIRC2/AO in grad school (for binary KBOs) Ghez et al would often be before/after us. AO imaging is not a big field.
