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?

Why yes this was filmed and edited in a single day. Thanks for noticing. Yes I am exhausted.

👩🏽‍💻 I'm Dr Becky Smethurst, an astrophysicist at University of Oxford (Christ Church). I love making videos about science with an unnatural level of enthusiasm. I like to focus on *how* we know things, not just what we know. And especially, the things we still don't know. If you've ever wondered about something in space and couldn't find an answer online - you can ask me! My day job is to do research into how supermassive black holes can affect the galaxies that they live in. In particular, I look at whether the energy output from the disk of material orbiting around a growing supermassive black hole can stop a galaxy from forming stars.

The horrific atrocities that took place in the Congo Free State are often compared to the Holocaust, with king Leopold II of Belgium being compared to the Nazi leader Adolf Hitler. Between 1885 and 1908, Leopold II personally ruled the Congo, in sub Saharan Africa, which was largely unexplored at this time, as only the coastal areas had been claimed by other European countries. He named it the “Congo Free State,” which is rather ironic when you realise what went on there.
The local population was anything but free.
(1885-1908)
