Never before has such a bright 'chandelier' been seen anywhere else in the universe, anywhere else! In astronomical terms, this 'cosmic chandelier' is called 'pulsar'. The fate of such a brilliant pulsar has never been seen in the universe before. In the 'light of a thousand lamps' it is shining brightly in the space. Like 'thousands of chandeliers of light'! He was discovered exactly 50 years after the discovery of the first pulsar in the universe (198).
This 'cosmic chandelier' emits as much light and energy in one second, the same amount of light and energy in our sun erupts for three and a half years. Then understand what a huge amount of light the newly discovered pulsar is emitting. Whose name is 'NGC-5906-ULX'. This chandelier of thousands of lights is caught by the eyes of NASA's 'Nuestar' ('Nuclear Spectroscopic Telescope Array') telescope. Very recently. The pulsar has also been spotted by the European Space Agency's (ESA or 'ESA') 'XMM-Newton' satellite. This 'chandelier' of thousands of lights is 5 million light years away from us. That means, This rare pulsar was born before the birth of man or his ancestors on earth. Which is basically a neutron star. The shocking research paper was published in the international science journal Science on Tuesday. There is also a Bengali associate researcher in that international research team. Dhruvajyoti Bandyopadhyay is an Associate Professor in the Department of Astronomy at Johns Hopkins University. After analyzing the data sent by ESA satellites, another research paper has been published in the international science-journal 'Astrophysical Journal Letters'.
"If a star like the Sun or they are dying, they could be in two different situations," said lead researcher Gian Luca Israel, an astronomer at the Italian INAF-Observatory Astronomy de Roma in ItalyEither they become black holes. Otherwise they become neutron stars or neutron stars. Pulsar is such a neutron star. The magnetic field on all four sides is impossibly strong. And that neutron star is spinning like a lattu. The radiation of light from the pulsar comes out in two streams of intense bright light. It spreads in space, much like the tail of a comet. "
"The discovery of this pulsar set a new record in the history of the brightest pulsar in the universe," said Dhruvajyoti Bandyopadhyay, an associate professor in the Department of Astronomy at Johns Hopkins University, a associate researcher by telephone from San Diego. Earlier, the brightest pulsar in the universe was 'M-72-X-2'. Which is far, far away from us, 12 million light years away. And that is in 'Cigar Galaxy' - 'Messier-72'. The newly discovered pulsar is 10 times brighter than the previous one. Not only that, astronomers have long thought that the brightness of a neutron star could be at least 1,000 times the brightness of this newly discovered pulsar. This discovery changed the way we think about pulsars and neutron stars. Even the black hole that forms after the end of the ten suns, as much light as comes out of its accretion disk, The luminosity of this pulsar is more than 10 times. However, we still do not understand how the newly discovered pulsar got so bright. It is still a mystery to us. Some say that the magnetic field of that pulsar is impossibly strong. The strong gravitational force of the neutron star pulls the cosmic objects towards the star, the star's impossibly strong magnetic field scattering it in various directions in space.
Another rare event occurred 50 years after the discovery of the Pulsar. Earlier this year, Hadish Mill was the first in the universe to have a 'White Dwarf Pulsar' named 'AR-Scorpio'. Which is 360 light years away from us. 'Scorpios' in the constellation. The white dwarf star from which this pulsar originated is about 200,000 times larger than our planet, even though it is about the size of our Earth. In three and a half hours, the pulsar is spinning its cold star. The pulsar was discovered by astronomers David Buckley of the South African Astronomical Observatory and a team from the University of Warwick. Their research paper was published in the journal Nature-Astronomy.
Dipankar Bhattacharya, a professor of astronomy at Ayuka, Pune's head of science operations for India's Astrosat satellite, says: "This is definitely a new discovery. Because, since the discovery of the first pulsar in 1967, astronomers have had a rough idea of the existence of such a pulsar. But such a pulsar was not found at all. The 'Crab Pulsar' (30 times a second), which spins at a very high speed, was discovered, and the 'White Dwarf Pulsar' seemed to be a fantasy. The discovery, in that sense, gave the almost abandoned astronomers a boost. Because, the 'White Dwarf Pulsar' can't spin so fast. I think that in the near future, more such 'White Dwarf Pulsars' will be found in the universe. "
