Stars (Including 1 Daredevil) Circle the Milky Way's Monster Black Hole (Time-Lapse) by space.com

Spectacular time-lapse footage from the European Southern Observatory's Very Large Telescope (VLT) in Chile captures stars orbiting the black hole at the center of the Milky Way, including one daring star that circles incredibly close.

A monster black hole called Sagittarius A lies at the heart of the Milky Way, about 26,000 light-years away from Earth. The footage, taken during a 26-year-long observation campaign, revealed that a small group of stars orbit this gravitational monster at high speed.


Stars orbiting the black hole at the heart of the Milky Way by space.com – This time-lapse video from the NACO instrument on ESO's Very Large Telescope in Chile shows stars orbiting the supermassive black hole that lies at the heart of the Milky Way over a period of nearly 20 years.


Simulation of the orbits of stars around the black hole at the centre of the Milky Waby space.com – This simulation shows the orbits of a tight group of stars close to the supermassive blackhole at the heart of the Milky Way. During 2018 one of these stars, S2, passed very close to the black hole and was the subject of intense scrutiny with ESO telescope. Its behaviour matched the predictions of Einsteins's general relativity and was inconsistent with simpler Newtonian gravity.
