My sort of astronomy
In more recent news: The first images of our own. I love the three bright spots and wonder if it's a trick of the camera, or if there is something unique going on there around the black hole.Fascinating announcement earlier today.
Another article says that it’s in the middle of a nearby galaxy 55 Million light years away. Funny how the concept of nearby changes with scale lol.
The image of the black hole as captured by eight telescopes on Earth

A black hole surrounded by swirling ring of fire has been pictured by scientists for the first time in an image described as ‘the gates of hell, at the end of space and time.’
The phenomenon which has never been observed before shows superheated matter being pulled towards the event horizon after which nothing can escape.
I don’t think it’s a trick of the camera because of that averaging technique. It might be some artefact of the maths technique or it might just be random noise. The latter is more unlikely the more samples go into the averaging.In more recent news: The first images of our own.

This image released by the Event Horizon Telescope Collaboration, Thursday, May 12, 2022, shows a black hole at the center of our Milky Way galaxy. The Milky Way black hole is called Sagittarius A*, near the border of Sagittarius and Scorpius constellations. It is 4 million times more massive than our sun. The image was made by eight synchronized radio telescopes around the world.
It took 5 years to get that image. The spots are not in every image taken, rather they're the result of computational averaging of all images.
Good find! That really confirms that the dots are real and not a feature of the detection equipment.Check my recent What YouTube Videos Are You Watching Right Now post for a video from Veritasium that well explains the “three dots” and imaging.
