For astronomers, the Black Hole is the most complicated thing in the Universe. No information could be obtained directly from them. These occur within an invisible boundary known as Event Horizon.
Even the light inside it does not come out. But in recent research, astronomers have captured such signatures of event horizons, in which they can be distinguished specifically from their size neutron stars.
Acquiring complete information about the black hole is one of the most challenging goals of physical and astronomy today. So far, only one supermassive black hole, whose weight is equal to 6 billion suns, has been captured. For this, radio distractions around that blackhole were used.
In this study, the signals that a team of international physicists has captured clearly distinguish the event horizon from the neutron star. Neutron stars are blackhole in shape and weight but are limited in the solid surface. This research has been accepted for publication in the journal Monthly Notices of the Royal Astronomical Society.
These clues are still seen as the clearest and most corroborative evidence ever caught about stellar-mass black holes. These black holes under the weight of the stars are ten times more than the weight of the Sun, but they can distort the spacetime around them by a million trillion times more than the supermassive black hole.
Therefore, such black holes are very important for studies. When such black holes merge, they can be known by gravity waves. Such waves are generated for a very short time. In such a way, the means of obtaining clear evidence of the presence of black holes is considered a very important discovery.
Astronomers are excited to find evidence of the presence of a permanent star blackhole. This black hole is emitting x-rays emitted during swallowing the nearby star material. To validate its presence, researchers used old X-ray data that they had found from a closed satellite Rossi X-ray timing explorer.
Researchers detected the effect of the absence of solid surface from X-ray radiation and found very strong signs of a rapidly growing stellar-mass black hole. Sudeep Bhattacharya, the researcher at the Tata Institute of Fundamental Research in India, says that the study has provided the most robust and permanent indication of black holes from cosmic X-rays from the satellite.
These black holes are compared to neutron stars, which are the collapsed center after the end of a massive star. Their weight is equal to 10 to 25 suns. But still, they are one of the smallest and thickest bodies. Distinguishing between them and their size black hole so far was difficult.
The stars shine at their center from the energy produced by fusion or fusion of hydrogen into helium. Due to the balance of the two forces, the star glows permanently for a long time - the gravity of its own substance that tries to make it smaller by narrowing it, and the second is the radiation emanating from the center that wants to expand it.
Therefore, when the fuel is exhausted in the central part of the star, it starts to shrink. After death, stars with a mass like the Sun become white Vamana or White Dwarf stars, which then gradually cool down and disappear from the visible sky.
When large stars of mass many times the sun die, they have a severe explosion called a supernova explosion. A lot of star matter spreads in all four directions in the universe and a dense small mass remains in the center. It is called a neutron star.
The neutron star is so dense that one teaspoonful of its substance weighs several tons. In stars with even greater mass, gravity continues to shrink even further after the supernova explosion. It becomes so dense and so gravitational that even a ray of light cannot come out of there. In such a situation, it could not save his existence.
