Supermassive Black Hole in Milky Way pictured for First Time

A supermassive black hole that lives at the centre of our galaxy, the Milky Way, has been pictured for the very first time.

For scale, the ring is roughly the size of Mercury's orbit around our star. Fortunately, this monster is a long, long way away - some 26,000 light-years in the distance - so there's no possibility of us ever coming to any danger.


The Event Horizon Telescope collaboration just released the first ever image of the Milky Way’s supermassive black hole (the same group that took the first ever image of a black hole in 2019 - the one in the centre of the Messier 87 galaxy).


What do we learn from this image?

Why is it orange?

Why is it different to the M87 image?

Why is it blurry?


And can we observe the same thing with the James Webb Space Telescope?
