Here's a neat little video of stars in the galactic centre: https://www.youtube.com/watch?v=TF8THY5spmo

It accompanies this press release about testing general relativity with the star S2.

Yes, these are great observations. I am currently contemplating how to simulate in celestia.Sci the 'S2 - black hole' encounter with gravitational redshift of the star S2,

along with some exciting gravitational lensing display of the 'black-hole - LMC' pair. Here is an example from
https://upload.wikimedia.org/wikipedia/ ... BH_LMC.png

All required tools are available in celestia.Sci!, and the data are published in the recent scientific literature.

Cheers,
Fridger
