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 of an ultra-diffuse central region, which is 2 mag fainter than the faintest depleted core of any early-type galaxy (ETG) dynamically modelled.Researchers also collected new photometric data at the Wendelstein observatory which confirms the existence of unusual, near-exponential light profile of the galaxy's core. “We use orbit-based, axisymmetric Schwarzschild models to analyse the stellar kinematics of Holm 15A from new high-resolution, wide-field spectral observations obtained with MUSE at the VLT. We find a supermassive black hole (SMBH) with a mass of (4.0 +- 0.80) x 10^10 solar masses at the center of Holm 15A

V616-MONOCEROTIS —NEAREST BLACKHOLE TO THE EARTH

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. Because the K-type star has been pulled into an  elliptical  shape, the amount of surface area visible, and th

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 radiation left over a

PULSARS

PULSARS PULSARS are highly magnetized neutron star which is rotating at high speed . It is White dwarf or neutron star which emits electromagnetic radiation. Pulsars have strong magnetic field which funnels jet out particles in form of radiation. This radiation can be detected only if radiation points towards earth. This particles create a beam of light. Three distinct classes of pulsars are currently known , according to the source of the power of the electromagnetic radiation: 1. Rotation-powered pulsars , where the loss of rotational energy of the star provides the power, 2.Acceration power pulsars where gravitational potential energy of accerated matter is power source.  3.Magnstars where decay of electromagnetic field of pulsar provide power.  APPLICATIONS:                                     pulsar are used to find unobservable celestial object known as neutron star which rotates near to speed of light.   Milliseconds pulsar allowed to test        G
