For the First Time Light Spotted Behind A Black Hole

Emission of X-Rays Has Been Observed for The Very First Time from The Far Side of a Black Hole

For the very first time in history, research scientists have been able to detect light from behind a massive black hole, and it has successfully fulfilled the prediction that has been rooted in the theory of general relativity by Albert Einstein. The astrophysicist Dan Wilkins along with his colleagues working at Stanford University has observed that the X-rays that are being released by the gigantic black hole in space which is located at the center point of a galaxy and are present at about 800 million light-years away from the planet Earth.

X-rays emission

The bright flares of lights that are seen to be escaping from the black hole are not unusual due to the fact that although light cannot travel outside from the black hole, the enormous amount of gravity that is present around the black hole can generate heat in materials up to millions of degrees centigrade. They also have the ability to release X-rays and radio waves into the surrounding environment.

Sometimes, some of these materials that have been super-heated are hurled out into outer space by rapid jets, including gamma rays and X-rays.

Although it has been noticed by Wilkins that some of the smaller flashes caused by the X-rays emission that occurred later and were to be of various different colors, and they all were coming from the black hole’s side located on the far end.

According to a statement given by Wilkins, who is also the study author along with being the research analyst at Stanford University’s Kavli Institute for Particle Astrophysics and Cosmology and the SLAC National Accelerator Laboratory, any of the light particles that are absorbed into the black hole is unable to come back outside, due to which they are unable to see any object that is present behind the black hole.

However, the strange nature of the black hole has actually allowed the observation to be possible. The reason by which the observations can be made is due to the fact that black holes are equivalent to warping space, twisting of magnetic fields, and bending light around itself.

The research study has been published in the journal named Nature last Wednesday.

According to Roger Blandford, who is also a co-author for this research study on black holes and a professor at Stanford University stated that almost five decades ago, when the astrophysicist at that time had started speculation regarding the behavior of the magnetic field, which is located close towards a black hole, they did not have any sort of idea that one day other scientists might be able to find techniques through which they would be able to directly observe and see in action the general theory of relativity given by Einstein so many years back.

Albert Einstein’s theory of relativity, or the idea that gravity is a matter which warps space-time, has persisted for about a century as several new discoveries regarding astronomy are being made every year.

Corona of black holes

Some of the black holes that are present in outer space have a corona, which is a ring of bright light that forms around the outer edge of a black hole as items from the outer space falls into it, due to which it later becomes heated to such extremely high temperatures. One way scientists have been able to study and provide maps of a black hole is through the emitted X-rays.

As gas enters into a black hole, it has the capability to spike the inside temperature to millions of degrees, due to which the electrons of atoms separate and creates a magnetic plasma. As black holes have some of the powerful gravitation pull towards the inside, it causes the formation of a magnetic field to arc above the black hole and twirl in a direction until it breaks off.

This mechanism is different from the corona formation of the sun or hot outer space atmosphere. The surface of the sun is covered in multiple magnetic fields, which then causes the formation of loops and plumes as they then interact with other charged particles that are also present inside the corona of the sun. Due to this reason, scientists are also calling the rings that are present around the black hole’s corona.
