Sagittarius A* is glowing 75 times.

SAGITTARIUS  A* SUDDENLY  FLASHING 75 TIMES BRIGHTER  SAGITTARIUS A*  is super massive  black hole at Center of our galaxy. It has 22 million km long radius. It is compact radio wave source which is situated at Sagittarius constellation. It is nearly 25640 light years away from earth.  It weighs 4 million solar masses. It's apparent size is 100 millionth degrees means watching tennis ball kept on moon from earth.  SAGITTARIUS A* IS GLOWING 75TIMES . There is something surprisingly happening in heart of our milky way. Sagittarius A* is too calm and take type black hole. He is not eating too much now,but eventually it started flared up 75 times than normal.  Researcher observed that Sgr A* is glowing 75times and luling  down. Scientist have  said this yo-yoing observed 26000years ago. Scientists from WM Keck observatory ,Hawaii took two hours lapse video of this wonder.Black hole always flash but this time it is too muc...

THE STAR BAFFLED SCIENTISTS WHICH LOOKS OLDER THAN OUR UNIVERSE  The age of our universe is 13.8 billion years. Scientists found a star who baffled them by it's age. Scientists have discovered star whose age is 14.5billion years. Now question is can our universe have stars older than itself?  This is condrum that universe is younger than its some stars.  HD 140283 : HD 140283, informally nicknamed the Methuselah star, is a metal-poor subgiant star about 200 light years away from the Earth in the constellation Libra, specifically toward Ophiuchus. Its apparent magnitude is 7.205.   It's a riddle of cosmic proportions: how can the universe contain stars older than itself?" physicist Robert Matthews  wrote for  The National ,  an English-language newspaper published in UAE. It could spark on new scientific revolution.  Dr Matthews, a member of the UK's Royal Astronomical Society, said recent measurements of the cosmic background...

HOLMBERG—15A. (THE BIGGEST BLACK HOLE EVER SPOTTED).

HOLMBERG — 15A THE BIGGEST BLACK HOLE EVER SPOTTED  Millions of black holes live in our galaxy Milky way. Black hol Esta are known for their gravitational pull, having escape velocity greater than speed of light. They are too massive. Scientists are looking for such black holes for further studies. In this process,  they came across a black hole which is nearly 40 billion times massive than sun which is more than black hole found in M87 galaxy which is nearly 16 billion times massive than sun.  HOLMBERG-15A is the biggest black hole ever spotted.  Holmberg 15A is a supergiant elliptical galaxy and the central dominant galaxy of the Abell 85 galaxy cluster in the constellation Cetus, about 700 million light-years from Earth. It was discovered c. 1937 by Erik Holmberg. The black hole is nearly 700 millions light year away from earth.  Researchers state that the brightest cluster galaxy (BCG) of the cool-core cluster Abell 85, consists ...
