ALMA spots twinkling heart of Milky Way
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found quasi-periodic flickers in millimeter-waves from the center of the Milky Way, Sagittarius (Sgr) A*. The team interpreted these blinks to be due to the rotation of radio spots circling the supermassive black hole with an orbit radius smaller than that of Mercury. This is an interesting clue to investigate space-time with extreme…
Why clouds form near black holes
Clouds in the greater universe are clumpy areas of greater density than their surroundings. Space telescopes have observed these cosmic clouds in the vicinity of supermassive black holes. Source: https://earthsky.org/space/cosmic-clouds-form-near-black-holes…
Abell 2384: Bending the bridge between two galaxy clusters
Several hundred million years ago, two galaxy clusters collided and then passed through each other. This mighty event released a flood of hot gas from each galaxy cluster that formed an unusual bridge between the two objects. This bridge is now being pummeled by particles driven away from a supermassive black hole. Source: https://phys.org/news/2020-05-abell-bridge-galaxy-clusters.html…
ESO Finds Star’s Orbit Around Black Hole Confirms Einstein’s General Relativity
puddingebola shares a report from ESO: Observations made with ESO’s Very Large Telescope (VLT) have revealed for the first time that a star orbiting the supermassive black hole at the centre of the Milky Way moves just as predicted by Einstein’s general theory of relativity. Its orbit is shaped like a rosette and not like an ellipse as predicted by Newton’s…
‘Dancing’ star’s weird, spirograph orbit proves Einstein right (again)

The orbit of a star near our galaxy’s black hole proves Einstein right
A star that swoops close to the Milky Way’s supermassive black hole has a strange, looping orbit that proves Einstein was right about the gravity of black holes Source: https://www.newscientist.com/article/2240816-the-orbit-of-a-star-near-our-galaxys-black-hole-proves-einstein-right/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Will SETI 2.0 lead to a discovery of intelligent aliens?

Something is lurking in the heart of Quasar 3C 279
One year ago, the Event Horizon Telescope (EHT) Collaboration published the first image of a black hole in the nearby radio galaxy M 87. Now the collaboration has extracted new information from the EHT data on the distant quasar 3C 279: they observed the finest detail ever seen in a jet produced by a supermassive black hole. New analyses, led by…
ALMA resolves gas impacted by young jets from supermassive black hole
Astronomers obtained the first resolved image of disturbed gaseous clouds in a galaxy 11 billion light-years away by using the Atacama Large Millimeter/submillimeter Array (ALMA). The team found that the disruption is caused by young powerful jets ejected from a supermassive black hole residing at the center of the host galaxy. This result will cast light on the mystery of the…
