Black Holes in Polarized Light.

[Polymath257]

The Event Horizon Telescope, which produced the first actual image of a black hole has managed to image the same black hole (the one at the core of M87) in polarized light. This gives information about the E&M environment close to the black hole, which helps us more fully understand what is going on there.

The previous image was the 2019 'Breakthrough of the Year'.

Both images were obtained by Long Distance Interferometry, which combines the observations of telescopes scattered across the world to give an effective telescope the size of the Earth.

The array illustration is cool, and includes the South Pole telescope.

I feel like people did in early 19th century when it was thought that there were no more discoveries to be made. Everything was understood, and the universe ran like a clock.
