On the 9th of April 2019, the first picture of a black hole was revealed to be taken, which is a historic and monumental milestone. The black hole in question is in the middle of the Messier 87 galaxy, 55 million light-years away, and the other black hole the team observed, Sagittarius A* in our own galaxy, is 26,000 light-years away (Landau). But how has it taken this long to get a picture of a black hole? Well, the way the EHT Project managed to get this picture was by linking up 8 radio telescopes around the world to get a telescope the size of Earth. The reason black holes have been incredibly hard to picture until now is that they’re extremely small on a galactic scale and they don’t emit their own light. Firstly, black holes can be very evasive to see because they are very small. For example, the event horizon of Sagittarius A* is smaller than the distance between the Sun and the Earth, and as well as that, there is a lot of stuff between us and a black hole, since they are ...
