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 maybe am completely wrong here, but i think this the article https://jasmine.nao.ac.jp/2024_2/EN/press_release_20241025_en.html

In the figure 3, the doppler shift considered seems way to high to me. If i get it correctly, we should be able to see the ring also also from top and bottom, so the center also should be in the plane of us viewing. the simulations seems to be from POV of someone much closer to BH, but we are really far, and then the effect should not be this much evident (I think).

Anyway, it is not necessarily this image that i am fond of. In a abstract sense. we have the raw image data, and just need a good image encoding algorithm to process this data. The fact that we got this raw data is amazing.
