With extra commentary by proper astronomer Professor Mike Merrifield, from the University of Nottingham.

Reminds me of when I hitchhiked through south of spain when I was 19. I slept in a corn field without a tent, and the sky above me was incredibly bright and beautiful. I, too, had never seen the milky way before. I'll never forget that night.

I'll never forget the "eureka" moment when I went with my boyfriend and his family to their cabin in northern Maine and saw the Milky Way for the first time.

+Carol Melancon yeah you cant see it in cities with all the light pollution even in small towns there is to much light pollution to see the milky way

When was in Afghanistan, I had to walk 2 miles every night to and from the drill rig I was working on, and often I would trip over the smallest objects because I was not looking down at my feet, I was admiring the Milky Way in all of its glory in the pitch black of the high desert. It also marked the first time I was able to see another galaxy with my own eyes when I finally figured out what Andromeda was. I would make my drillers take breaks just so I could teach them about the night sky.

Been up there twice now, both times I've got the feeling they don't appreciate Joe public taking any interest. Such a shame, it could kill any enthusiasm for astronomy that visitors might have. If I ran the place I'd make sure there were open days for us riff-raff.

@coldlogic1 it was quite high but not crazy (2,400m)... it does slightly affect many people (especially when lugging camera equipment around), but my shortness of breath might just be a general lack of fitness and excitement at seeing the telescope! ;)

So very few get to truly appreciate the beauty that is the night sky. Over 90% of the population, living in urban centres, get to see and recognize a few bright stars and constellations, but when you really see the Milky Way for all its glory, it's breathtaking, and there is no comparison.

The 10.4 m Gran Telescopio Canarias segmented reflector is made of 36 hexagonal ZeroDur segments Aluminium coating. However, the GTC also has 6 extra segments so whenever segments need to be recoated, these can be replaced without the telescope going out of ops. The 1.17 m secondary Beryllium mirror Nickel coating. The GTC saw first light with 12 mirror segments in July 2007, with all 36 segments in November 2009. The OSIRIS instrument will be used for transiting exoplanet atmosphere surveys.

Brady! Do you think maybe you can get the guys to talk about "adaptive optics" for a bit? It's something that's pretty much revolutionised stargazing, allowing ground-based telecopes to outperform even the Hubble. Also 00:32 = /watch?v=lI_0-kz4lR0#t=1m0s heheheh
