More space news and info at: http://www.coconutsciencelab.com - to peer deep into the night sky astronomers must use telescopes with enormous primary mirrors. Creating such mirrors involves many challenges. Please rate and comment, thanks! Credits: ESO Visual design and editing: Martin Kornmesser and Luis Calçada. Editing: Herbert Zodet.

i am new to telescopes but i notice most high magnification shoots looks like they have been taken with an inch of water on the telescopes. i have read it's do to the atmosphere and on the bigger telescopes they are using manipulated mirrors witch costs way more then most can afford.would not a bunch of small cameras at the eye piece do the same thing but be cost effective? just like the usa surveillance drones have. then the telescope would be self correcting not for the complete field of view witch no camera can do but if broken down in to many sections you would have a lot better view/shoot

why cant they just cast concrete and make a really thin and shiny mirror. is concrete going to bend?
-
I will be billionare soon, Them i need a 10 km wide telescope mirror, sending a huge 3d printer into space, in 5 years time i can read alines news papers :)

what wates time big mirro spend thas money flight direct space contruction space chip more beter

turn down the music channel and bring up the speaker. The music is too loud.

Check out Antoine Labeyrie's work for nextgen telescopes.

Back in the day people were amazed by the 100" Wilson then followed by the massive 200" Palomar scopes, which were hugh technological achievements for the time and in my world, even today. It was good to hear that some of those older scopes are still in operation with the ability to upgrade them to modern adaptive optics. I wonder what's next for land based instruments.

why not make 100 meter telescope?..i mean with current technology and scientist can find more ways to do it,,
-
Interesting Cast but those names "Extremely large", "Very large" are just unscientific and limited...

It occurs to me that these advanced optics could be used as anti-satellite weapons.
Need a satellite shot down? Just focus a one square kilometer beam of sunlight onto it.
Also, by using a ground based, and a space based telescope in tandem, One could theoretically target any point on one hemisphere of the Earth with said beam.
The space-aged equivalent of Archimedes' Death Ray.
