The black hole seen in the picture measures 40 billion km across, is three million times the size of the Earth and has been described by scientists as "a monster".

They are not empty, but instead consist of a huge amount of matter packed densely into a small area, which gives it an immense gravitational pull.
Why is the first ever image of black hole important?
Astrophysicist Dr Rajan Chhetri has this to say.
