After many years of work and many hype, researchers working on the project of the Horseshop Telescope Project finally released the first picture taken by an actual black hole this week. The relatively low-res image is incredible, and the fact that scientists are able to capture an image of black holes from a distance of approximately 55 million light-years away is completely mind- boggling.
But wait, we live in the Milky Way galaxy, and in the middle of it is what scientists believe is a massive black hole called Sagittarius A *. Our galaxy is almost 150,000 to 200,000 light years only, so it's not easy to shoot our own black hole instead?
That's a question I've seen several times in social media since The first black hole photo starts to move, and it's a great one. It takes sense to get a picture of the nearest black hole on Earth, especially if we want to see it in great detail. Unfortunately, Earth ̵
The Milky Way is a spiral galaxy with long arms full of hundreds of billions of stars, and it is arranged like a flat disc. If you look at the entire expanse from its face, you can quickly see our problem:
The dot labeled "Sun" is where our solar system lives in space, riding on side of one of the long, curved arms of the Milky Way. From the high position, looking at the direction of the center of the universe looks like this:
Trying to see our hole in our own black hole is like trying to see the center of the wide forest standing while standing with its fringe. There are so many things on the road, including stars, planets, gas, and dust. In order to have any hope of seeing our own black hole we would like to send a ten spacecraft, or even hundreds of thousands of light years away, allowing them to view the Milky Way from his face rather than on its side
Thus, The Event Horizon Telescope team made the next best thing, which is to hunt for a galaxy in the right orientation observed from Earth, and Messier 87 – and its black hole known as M87 – has proven to be a perfect candidate.
