For decades scientist have been working to find black holes, how they work, why they exist in the first place etc. Other than that scientist worked on many theories and equations without even knowing how the even looked like.
There has been many illustration and images on black holes. Even in the movie “Interstellar”, you can see one the best-illustrated picture of a black hole, Christopher Nolan and his crew worked for months to develop such a clear picture of the black hole.
So what is a black hole?
Black holes are some of the most perplexing objects in the entire Universe. Objects so dense, where gravitation is so strong, that nothing, not even light, can ever escape from it.
Many physical black holes have been identified, from stellar-mass scale ones in our own galaxy to supermassive ones at the centres of the majority of galaxies, many millions or even billions of times the mass of our Sun. The key property surrounding the event horizon, that light can never escape from within it, sets up a boundary in space: once you cross it, you’re doomed to hit the central singularity. But what would you see as you fell in? Would the lights stay on, or would the Universe go dark? At last, physics has deciphered the answer, and it’s gorgeous. The scientist is always working on the physics behind the black and why the existed there.
” US-based physicist John Archibald Wheeler coined the ‘black hole’ term in the mid-1960s. The terminology means a point located in space where the matter is so compressed as to create a gravity field through which even light cannot pass through. “
Each and every day, Sun’s in other planetary system dies and the birth of a new black hole takes place, Maybe after another billion years from now our sun dies and becomes a black hole, where will humans be by that time!?
Nobody actually knew how the black hole looked like until the scientist released the first image of the black hole which they released recently to the world.
The image of the black hole, which has been released by the scientists, is located in a galaxy known as M87. This is 50 million light years away from the earth. Taking an image of M87’s supermassive black hole at such distance is comparable to photographing a pebble on the Moon. At the same scale of compression, Earth would fit inside a thimble. The Sun would measure a mere six kilometres edge-to-edge, as per the reports.
Behind every pioneering scientific discovery, there have been a great amount of teamwork and years of toil that led to the eureka moment.
Instead of building a giant telescope, scientists combined many observatories. In April 2017, eight radio telescopes positioned in Arizona, Hawaii, Spain, Chile, Mexico and the South Pole zeroed in on Sagittarius A* and M87. In the end, M87 turned out to be more photogenic.
Helger Rottmann from the Max Planck Institute, who was involved in the project, said the team awaited for data from the South Pole Telescope. However, this came six months later from April due to the harsh climate prevalent during the southern hemisphere winter. The date came on December 23, 2017. It took another year to compile the data to make the image.
