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...

V616-MONOCEROTIS —NEAREST BLACKHOLE TO THE EARTH

Image
V616 MONOCEROTIS —  THE  NEAREST  BLACK  HOLE  TO  EARTH MILKY WAY  has millions of black hole. Our galaxy has super massive black hole at it's center  SAGGARITUS A which is too much powerful, but it is too far from earth.Black holes are destroyer. They engulf everything which is full of matter. Then question arises is there any danger to earth from any black hole?  As per observations V616 MONOCEROTIS is the closest known black hole from earth.  It is also known as A0620-00. This system is binary star in MONOCEROUS constellation.  This constellation only contains two objects.  SIZE   = APPROX (LONDON CITY)  DISTANCE FROM EARTH -   3457  light years MASS OF A0620-00 =   6 TO 9  TIMES OF SUN The black hole in A0620-00 pulls matter from the K-type star into an accretion disk.  The accretion disk emits significant amounts of visible light and X-rays.

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...
