Black hole in the centre of milky way may be 'flickering': Research

black hole detected in centre of Milky Way, called Sagittarius A*, has been subject of interest for astromers and recently scientists found evidence that massive hole may be flickering. According to a study published in Astrophysical Journal Letters, astromers studied black hole using ALMA (Atacama Large Millimeter/submillimeter Array), an extremely powerful telescope. After looking closely, scientists saw massive black hole, which is said to be four times bigger than Sun, “flickering”. 

A team of Japanese researchers studied Sagittarius A* and said that y obtained high-quality data of rio-wave intensity variations fro 10 days, 70 minutes per day. Tomoharu Oka, a co-author of study said that emission double is related with some ‘exotic phemena’ occurring at very vicinity of supermassive black hole. researchers suspect that activity may have something to do with black hole’s accretion disk. 

scientist also ded that a black hole is essentially invisible to telescopes. ted that dense, dark Goliaths don't emit any detectable form of light because ir gravitational pull is so exceptional light cant escape. However, astromers were able to detect hot gas that orbits around black holes, trapped by ir gravity.

‘Flickering’ could help find more about black hole

Furrmore, team ded that “flickering” could help m find more about how black hole behaves and how gas is accreting around its centre. y, however, also claimed that blinking motion is too fast to be capture in photographs. 

Meanwhile, black holes are one such mysterious phemen that has always captured imagination of scientists all over world. From Albert Einstien to Stephen Hawkings, black holes have never failed to amaze scientists opening gates for furr research. first im of a black hole was published in April 2019 following observations me by Event Horizon Telescope in 2017 of supermassive black hole in Messier 87's galactic centre.
