Some info about the black hole to put in perspective just how impressive this is:

 

- It's the supermassive black hole at the centre of the Messier 87 galaxy

 

- It's 55 million light years away from earth

 

- It's mass is 6.5 billion times the mass of the Sun

 

- The event horizon is 40 billion km across. For reference, the distance from the Sun to Neptune, the outer most planet in our Solar System, is 4.5 billion km

 

 

Just completely insane scales all round, and we've just gone and taken a snap of it. Also rumors are circulating that an image of Sagittarius A, the black hole at the center of our galaxy, may be soon to follow.

so if you observed something like a space ship fall into a black hole. They would experience it in a normal time frame, but because the gravity is so intense It would take a thousand years for observers to watch the ship go over the event horizon. I think . Not sure

They (as in the light from them) would get red shifted to nothing over an arbitrarily(infinitely?) long time.  You wouldn't actually be able to see anything pass over the event horizon.

So if we encounter Sectoids on an exoplanet, then that technically makes us the aliens.

Also, NASA officially hinting at a lunar colony in as soon as five years
