A team of scientists discovered that the black holes emitted light, similar to "burping", when they eat gas and stars around them, and this change in the brightness is directly related to its size.
Supermassive black holes (SMBHs), millions to billions of times more massive than the Sun, are typically found in the centre of galaxies, including one at the centre of the Milky Way, known as Sagittarius A.
According to scientists, when the black holes are inactive, they do not release a lot of light but when they are active, usually in the dawn of the universe and in case they consume all known materials, they release radiation larger than their galaxies, with flashing light lasting for hours to decades.
Colin Burke, the main author of the study said, “There have been many studies which revealed potential relations between the spotted beating and the massive mass of the black hole, but the results were not crucial and sometimes controversial.
The massive black hole swallows a large amount of material and when this material starts to move at high speed due to the gravity of the black hole, it emit intuitive energy, which pushes the surrounding material out. This is how the galactic wind is created.
It is still not clear why the flickering occurs due to "physical processes that are not yet understood."
Smaller supermassive black holes have a shorter timescale, while conversely, larger supermassive black holes have a longer timescale.
The unexpected thin disc of material was found encircling a supermassive black hole at the heart of the spiral galaxy NGC 3147, located 130 million light-years away, according to a Study published in the journal Monthly Notices of the Royal Astronomical Society.
The world is finally about to see a black hole — not an artist’s impression or a computer-generated likeness, but the real thing. At six press conferences across the globe scheduled for 1300 GMT on Wednesday,

With Afghanistan's economy deep in crisis - billions of dollars in aid and reserves have been cut off and ordinary people have little money even for basics.
It sits in a rugged, inaccessible valley along the Harirud River, well off Afghanistan’s tourist track even in the 1960s, when the country was a magnet for hardy Western travellers.
