Magnetic field around a black hole mapped for the first time
New Delhi : A detailed new view of a black hole at the centre of the M87 galaxy, 55 million light-years from Earth, captured by Event Horizon Telescope (EHT) collaboration—an international team of radio astronomers—was released on Wednesday.
In order to take a picture of this black hole, in the year 2017, 300 scientists internationally started an experiment with 11 radio telescopes. The first picture of this black hole was revealed in the year 2019. Because this black hole is located in the center of the galaxy Messier 87 – M87. This is 5.50 million light-years away from Galaxy Earth. Many complications were encountered in finding and photographing it.

Now, by analyzing new data, scientists have measured the magnetic field moving around it. This black hole is partially polarised. This means that the rays of light are vibrating in the same plane. This indicates that the rays of light are passing through a hot and magnetic field. This magnetic field is moving slowly around the black hole.
Two new study papers related to this black hole have been published on 24 March in The Astrophysical Journal. This magnetic force is so powerful that it is even pulling things from space and throwing energy and space objects as a jet 5000 light years away. Due to this magnetic force, there is a red, orange, yellow circle around the black hole.
Coordinator of EHT Theory Working Group and University of Colorado astrophysicist Jason Dexter says that the best scientists around the world are working to study the magnetic field surrounding this black hole. We are surprised that there is a rotating magnetic field here which is polarized.
The weight of this black hole is 65 crores solar mass. This black hole is extracting hot and magnetic plasma from all around. Because of this, electromagnetic rays are moving around this black hole.
Event Horizon Telescope Traces Magnetic Fields Around a Black Hole
We got our first up-close look at the shadow of a black hole nearly two years ago. Now, the same telescope is giving us a fresh perspective. https://t.co/POlE6yaZ9t @ehtelescope #M87 pic.twitter.com/sDXQQuVMUK
