Groundbreaking press release this morning that the Event Horizon Telescope has successfully imaged the supermassive black hole that resides at the heart of our own galaxy.
Huge congratulations to the EHT team for making 2022 the year for amazing space imagery.

Bah Gawd that's Sauron's music!

Amazing and heart-breaking at the same time what kind of collaboration humankind is capable of. Why not all the time? ?

Derek from Veritasium just released a great video about it https://youtu.be/Q1bSDnuIPbo

That's a donut.

IIRC this is like taking a photo of a 3 story apartment building in the UK from LA (if the Earth were invisible).

What's doubly impressive is this had to be imaged through the bulk of the galactic disc. That's a hell of a lot of signal to wade through.

Thank you for the clarification, it is appreciated.

Cool. This is the first pic of the black hole that is at the centre of the milky way. They first imaged a black hole in 2019 (diff galaxy)

M87 at 55 million light years away.

Which, I mean, is insane. So cool!

Totally. I’ll probably never set foot on another planet, but to see this is a good substitute! I hope there will be more pictures of it.

Is it supposed to be blurry? Serious question

The size/distance ratio is the same as if you took a photo of a donut on the surface of the moon from earth. So, quite impressive as is.

This is the sharpest picture they ever made. (I saw the live persco on YT this afternoon.)

Yes, to understand better how this came to be and what you see check some info on M87 the first black hole we took a pic from
DrLOAC
It’s a long duration exposure but the accretion disk is whipping around the black hole at a significant fraction of light speed. So yes

Sweet! Thanks!
