It's pretty amazing. I didn't know you were an astronut though. =) I do astrophysics and exoplanet research in my spare time now and then. It really fascinates me. We're on the cusp of learning so much more about our galactic neighborhood...
Wha? Current astronomical theories about the age of the universe puts it at between 14.5 and 16 billion years old. Where did you hear about something 180 billion years old? Gravitational lensing, perhaps?
Speaking of gravity and the speed of light and such, I have a strong sneaking suspicion that light's speed is not even remotely a constant and that gravity over vast distance has peculiar effects. I think until we get out of our current frame of reference (i.e. our solar system) we're not going to realize and be able to understand and predict those peculiarities...
But yes, astrophysics are fascinating, and I'm especially interested in and involved with exoplanet theory and research. =D I need to explore the two moons of Overbear one of these days too. ;)

What blows me away is the distances we are talking about, I mean the light from the one galaxy that shouldn't exist is 180 billion years old...wow.
