Ummmm...unless they're planning to rebuild a Saturn V and an Apollo lander any way they go will be a way they've never gone before.

Mindboggling stuff happening tomorrow:

Registered 12 years agoStrange, I was lead to believe it was going to be full of bookcases.
It’s amazing that we have the technical ability to make such a picture, what’s even more amazing to me is that these were predicted by guys using nothing more than a sheet of paper and a pencil and just thinking really hard about the laws of nature. Yay science \o/ -

Registered 8 years agoThat is what I love so much about it.
It so well represents what was predicted 100 years ago.
Can't wait to share this with my a level physics pupils after the holidays! -

There is so much out there!

Found this to be a good explanation of what we're 'seeing'. -

Registered 15 years agoAnyone watch the full documentary on BB4 last night?
Really interesting seeing how they linked up all the satellites and how they got the final images, from running various lines of code/math. -

Registered 6 years agoI believe it was just the best candidate for orientation (closer ones are more "edge on", so there's more mass obscuring any view of the centre - including our own). -
@ZuluHero Yep. They needed a big one (supermassive) as these have such a huge gravitational force that nothing including light can escape from them. This leads to the creation of the halo as matter including photons are dragged around the black hole. The theory is that the supermassive black holes are located at the centre of galaxies.
They are trying to take a photo of the one believed to be at the centre of the milky way. -

Registered 12 years agoThis is the exact question I was asking myself throughout the BBC4 documentary last night... Why was it necessary to view a black hole so far away, if they're considered to be present at the centre of most or all galaxies, including our own galaxy?
This is one of the most fundamental aspects of the problem they were attempting to solve, and the reason they needed to construct such a vast and complicated telescope array, yet was left completely unaddressed.
I mean, I have a casual interest in astronomy, so I suspected they needed a large black hole that wasn't obscured by stars in the galactic center, but the documentary never confirmed this. Really poor considering it was a BBC documentary. -

Registered 12 years agoThing is, we’re in the disk of our galaxy, and there’s a shitload of gas and dust between us and the galactic center, plus is an average sized massive black hole that isn’t very active, there is not a lot of stuff falling in right now.
The one in M87 is much bigger and very active. -

Registered 15 years agoI thought the reason was they had 2 'spots in the sky' where they could see stars moving erratically so best guess they would point the cluster there.
Quite a lot of time/money involved, so they pointed it at the biggest potential Black Hole, with the best chance of getting results. -
What blew my mind is that each telescope collects 350TB of data per day. And the fastest way to transmit that data is to send a bunch of HDDs by plane to the processing center.
