On Wednesday the Event Horizon Telescope team revealed the first ever image of a black hole.
The picture is an image of Messier 87's supermassive black hole in the center of the Virgo galaxy cluster, which is about 55 million light-years from the Earth. The black hole photographed has a mass 6.5 billion times that of the Sun.
The Event Horizon Telescope (EHT), is an international collaboration with multiple countries working together to essentially build an Earth-sized telescope by linking radio dishes from around the world.
The achievement is impressive but of course the internet is having a little fun with the image. Here are some of the best online reactions.
