The detection of a binary star system close to the supermassive black hole in the center of Milky Way is shared in @NatureComms. This provides insights about dynamics & evolution of stars in vicinity of our Galaxy’s supermassive black hole, Sagittarius A*: https://t.co/jalFW6Hup1

A paper in @NatureComms reports the detection of a binary star system close to the supermassive black hole in the center of the Milky Way. Such systems have been predicted but have previously eluded detection. https://t.co/qpPqu6Aztx

After all, black holes are not as destructive as we thought! 😮

Using ESO’s #VLT, astronomers have discovered, for the first time ever, a binary star close to our galaxy's supermassive #BlackHole.

An international team of researchers discovered signs of an intermediate-mass black hole in the star cluster IRS 13, near the supermassive black hole Sagittarius A* at the center of our galaxy.

Observations from various telescopes, including @almaobs and @chandraxray suggest that the cluster's compact shape and the orderly motion of its stars are influenced by this black hole.

It’s all wibbly-wobbly star material.

Scientists have used our NICER telescope to observe the wobbly leftovers of a black hole’s snack. By watching how the wobble changed over time, they determined how fast the black hole was spinning. Learn more: https://t.co/VBWRr11Ifa

It has long been predicted that after the supermassive black hole disrupts a star, the newly formed accretion disc should precess. Finally, we have detected it!!! Read our results in the "fresh from the oven" Nature article: https://t.co/1V9jVaytzO
