Wow! I'm utterly speechless.

I love space "browsers" - I lose myself in them, just clicking through all the entities.

Also TIL that there are satellite galaxies, and I've never noticed those on other toys/tools like this. I always though Andromeda was the closest galaxy, but it is FAR away compared to `Sgr dSph` which is within 50kly from the center of the Milky Way.
