Stars dancing around a Black Hole

Dear all,
let me share with you a (relatively recent, 2018) piece of news, which brings me astonishment as when I was looking at fireflies in my youthness.
See the incredible **dance of stars in the video** below, published on twitter
and a brief summary of the scientific findings here

“First Successful Test of Einstein’s General Relativity Near Supermassive Black Hole
Culmination of 26 years of ESO observations of the heart of the Milky Way”

“This is the second time that we have observed the **close passage of S2 [Note: a star named S2] around the black hole in our galactic centre**. But this time, because of much improved instrumentation, we were able to observe the star with unprecedented resolution,” explains one of the authors

All the pettiness and violence of mankind annihilated by the beauty and enormity of the cosmos.

This zoom video sequence makes dive us into the #MilkyWay central region where lurks a 4-M solar mass BH, surrounded by a swarm of stars orbiting rapidly.

We first see the stars in motion, thanks to 26 yrs of data from #ESO's #telescopes.
