Sagittarius A* Black hole
(lemmings.world)
This is (in my opinion) one of the single biggest achievements of humanity.
Image of Sagittarius A* black hole at center of our Galaxy, taken by Event Horizon Telescope team. This one is also refined with magnetic field lines.
I don't remember what was the exact source for me, but one of the possible ones is https://s3.amazonaws.com/cms.ipressroom.com/173/files/20247/66c7d3d62cfac2492a9bdd54_Sagittarius+A/Sagittarius+A_hero.jpg. I just made it grayscale, some dimming, and resizing, to not cover whole of screen.
i mean really i feel like it's pretty incorrect to say that either of them is a true correct image, it's not at all what we would see if we looked at it up close.
Both versions show that one side is brighter, and that's about all there is to it at this distance and resolution.
