Yeah see I’d think they’d be streaked all the time. The dimmer the light the longer the exposure you need and then the movement of the earth would be more pronounced! Again, obviously they’ve figured out all of this or we wouldn’t have these images. UNLESS the moon landing and all of modern space photography is a hoax and obviously the earth is flat. Ha

Hank Azaria was on a talk show this week…and talking about his voice work with “The Simpsons” and was asked about who was the most difficult guest voice actor.
He mentioned Stephen Hawking…and how Dr. Hawking basically stood up the cast for rehearsal being late several times and keeping everyone on the clock waiting for him to show up.
One of the writers remarked “This man has no concept of time”

Given that Voyager 1 just left “our solar system”, for some definition of our solar system, I suppose it’s “only” the size of our solar system.

And it takes two whole days for stuff to revolve around it:
Hard to photograph
It was easiest to take a picture of M87. “It is very difficult to photograph the black hole in our Milky Way, because the material around it moves very fast: the vortex rotates around its axis in 20 minutes. … With M87, the matter revolves around the hole in two days, so it’s easier to photograph”, says Falcke.

I’m surprised it took 8 hours.

So, I have a sort of science-y question. Presumably, from what I know about the theory of black hole formation, they’re spherical. Three-dimensional. Matter infalls from every direction. In other words, the event “horizon” shouldn’t resemble anything like Jupiter’s rings. It should surround the entire thing and so we shouldn’t be able to see anything but the event horizon. The actual black hole, like in the image, shouldn’t be visible.
So why is it? And if there is a reason it is, how is it scientists were just fortunate to pick one where the event horizon wasn’t presented edge-on, or at an angle of some sort?

The black hole itself is spherical, and is the black void in the center of the image. However, for Physics Reasons like tidal forces and such, material falling inward toward the black hole will collapse into a disk. The light being emitted by this accretion disc as it’s accelerated to nearly the speed of light (and heated by friction and other forces in the process) is what we’re seeing in this image.
I cannot recommend highly enough the Veritasium video that was posted earlier in this thread for an explainer of what we’re seeing and why it looks that way.
It looks like he’s posted his follow-up, as well:
