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 first image of the Milky Way's supermassive black hole, Sagittarius A*, has been released by the Event Horizon Telescope. Sgr A* is a supermassive black hole that lies 27,000 light years away from Earth at the center of the galaxy. Its mass is about 4 million times the mass of the Sun but a thousand times less than the black hole at the center of the M87 galaxy, the image of which was released back in 2019.

When in doubt, don't hesitate to ask
When something is not clear, you should go back and listen again.

When in doubt, don't hesitate to ask (Twi)
Once upon of time, God asked: 'Who could go to the devil and bring certain things from him?' But he wouldn't say what those things were. Nobody came forward except Kwaku Anansi. He went on his way, but had not been told what to collect. He went to a flock of birds to reason with them. He asked the birds to give him one feather each, and that he would reward them for them later. They granted him his request. He put on the feathers and Anansi became a beautiful bird. He flew back to the tree where God always sat and overheard him say that what he wanted form the devil were his sandals and staff. As soon as Anansi heard this he went on his way to the devil. The devil gave him a place to rest when he arrived. Anansi asked the devil for his staff to kill the big mosquitoes and asked him for his sandals so they wouldn't bit him in his feet. The devil gave him what he requested and as soon as he left, Anansi ran away. God asked him how he had known what to bring back. Anansi asked him about the beautiful bird and God replied he didn't know its name. Anansi answered: 'His name is: If something isn't clear, go back and listen again.'

Wisdom isn't found in one person (Anansi Storytelling)

Wisdom isn't found in one person
Anansi shows God how a lie can be more hurtful than a wound. God realizes that wisdom cannot be found in one person. He rewards Anansi by naming all stories Anansi stories.

Wisdom isn't found in one person (Twi)
Once upon if time God lived in his cottage. The name of the cottage was: There's no one besides me. Kwaku Anansi also lived in a cottage not so far away from him. The name of his cottage was: Wisdom isn't found in one person. They became good friends. One day kwaku Anansi asked God: 'What is more painful: the incision of Tribal marks or to be falsely accused of something?' God answered that a blade would cut your flesh, but when you are falsely accused of something you could just walk away and deny it. One day Kwaku Anansi went to God's cottage and relieved himselve on the stove. The next morning God's mother-in-law found the mess and was shocked and told everybody in the village. Meanwhile Kwaku Anansi hired the Rat to digg a tunnel to the room where God kept his talking drums. That same day the drums started talking and saying that God had done the deed. God couldn't bare the false accusations and wanted to kill himself. Kwaku Anansi reminded him of their conversation and God realised that false accusations could be as painful as the incisions of tribal marks. God now understood why Kwaku Anansi had named his cottage: Wisdom isn't found in one person. And from then on assigned all stories to his name. That is how all stories became Anansie stories.
