It takes about a century to take the very first picture of the black hole. Here are some really amazing and interesting facts you should know about the black hole and NASA’s first picture of it.

1. You can’t directly see a black hole. To achieve the necessary resolution to see a black hole directly a single telescope would need to be the size of planet earth.

2. The massive gravitational influence of a black hole distorts space and time in the near neighborhood. The closer you get to a black hole, the slower time runs. Material that gets too close to a black hole gets sucked in and can never escape.

3. In 2009 Event Horizon Telescope (EHT) is a collaboration of many Institution and sites to make a telescope the size of the earth, giving us the highest resolution to capture the image of Black Hole. It consists of 8 telescopes around the globe. In April 2019 we capture the very first image of the Black Hole.

4. The image is based on data from radio telescopes all over the world, so it’s not technically even a picture of a black hole. Black holes are, scientifically speaking, unseeable.

5. The black hole in Christopher Nolan’s ‘Interstellar’ wasn’t so far off from the real thing. It was all VFX but now as we have the real image of the Blackhole we can say that both looks quite the same. (If you haven’t watched Interstellar then you must, it’s an amazing movie.)

6. Material spirals into a black hole through an accretion disk — a disk of gas, dust, stars, and planets that fall into orbit the black hole.

7. The “point of no return” around a black hole is called the “event horizon”. This is the region where the gravity of the black hole overcomes the momentum of material spinning around it in the accretion disk. Once something crosses the event horizon, it is lost to the pull of the black hole.

8. Black holes were first proposed to exist in the 18th century but remained a mathematical curiosity until the first candidate black hole was found in 1964. Cygnus X-1 was first found a black hole, according to NASA, the black hole is 10 times more massive to the Sun. Nearby is a blue supergiant star that is about 20 times more massive than the Sun, which is bleeding due to the black hole and creating X-ray emissions.

9. Black holes do not emit radiation on their own. They are detected by the radiation given off as the material is heated in the accretion disk, and also by the black hole’s gravitational effect on other nearby objects (or light passing by).

10. There are at least three types of black holes, Primordial black holes are the smallest kinds and range in size from one atom’s size to a mountain’s mass. Stellar black holes, the most common type, are up to 20 times more massive than our own Sun and are likely sprinkled in the dozens within the Milky Way. And then there are the gargantuan ones in the centers of galaxies, called “supermassive black holes.” They’re each more than one million times more massive than the Sun. How these beasts formed is still being examined.

Using the Event Horizon Telescope, scientists obtained an image of the black hole at the center of galaxy M87, outlined by emission from hot gas swirling around it under the influence of strong gravity near its event horizon.
