Oh cool about HD!
I hear ya. And that’s just one section of the galaxy Andromeda!!!
I like this short space vid (2:10 min) and how the narrator ends it. Gives me chills and cracks me up at the same time. Starts with us on Earth, then MOOOVES outward...

Oh wow that was wild! “This is the Universe...It’s really REALLY big!” LOL! I like when he says “..the visible universe” meaning there’s more we haven’t seen yet. I think that’s because its light hasn’t reached us yet which I believe is one of the pieces of evidence they use for the big bang. If the universe always existed, then the light from every star in the universe would have hit us by now, at least those stars that didn’t form too recently, and it would light up the sky like day. But there are stars that are so far out there that even though the universe is 13 billion years old the light from those stars still hasn’t reached us yet. How freakin’ insane it that? Light travels at 186,000 miles per second and 13 billion years still ain’t long enough for that light to reach us which is mind blowing to me how insanely vast it is.
