reactolite Posted July 13, 2014 Share Posted July 13, 2014 European Extremely Large Telescope - 40 mts. And this was a compromise as originally they wanted 100mts, aperture fever or what!!Will this behemoth have enough resolution to directly image planets outside our solar system? If not then just how big a telescope would be needed to do that? Link to comment Share on other sites More sharing options...
michael.h.f.wilkinson Posted July 13, 2014 Share Posted July 13, 2014 Spotting planets directly is not just a matter of resolving power. The hardest bit is to get rid of the glare of the star. I am not sure if that can be done from within the earth's atmosphere, even with adaptive optics Link to comment Share on other sites More sharing options...
Knight of Clear Skies Posted July 13, 2014 Share Posted July 13, 2014 Yes, it's some scope. Its science goals include direct imaging of exoplanets, possibly even rocky planets.Here's a nice graphic that shows the size of the mirror. Link to comment Share on other sites More sharing options...

laser_jock99 Posted July 14, 2014 Share Posted July 14, 2014 What happened to the Overwhelmingly Large Telescope then? Link to comment Share on other sites More sharing options...
alan687 Posted July 15, 2014 Share Posted July 15, 2014 i read that the original plan was for a 42m telescope but it was outside the budget so they removed a ring of mirrors reducing to to 39m, but it only costs a billion + a mountain to put it on so i might order one Link to comment Share on other sites More sharing options...
mjpfc Posted July 15, 2014 Share Posted July 15, 2014 I've just paced across my Garden - 13 Mtrs and only 36 feet above sea level.........What were they thinking!I wish they would consult before they go to development on these things.Looks like they'll have to go to Chile again.

Knight of Clear Skies Posted July 16, 2014 Share Posted July 16, 2014 What happened to the Overwhelmingly Large Telescope then?That one never got off the drawing board, we'll have to make do with extremely rather than overwhelmingly large for the time being. I guess Spinal Tap weren't on the committee. Link to comment Share on other sites More sharing options...
mjpfc Posted July 16, 2014 Share Posted July 16, 2014 Don't worry, the Chinese will weigh in soon with the "Crust crackingly Large" Telescope (Binocular). Link to comment Share on other sites More sharing options...
Kel Solaar Posted July 17, 2014 Share Posted July 17, 2014 Apparently they have trimmed the top of the Cerro Armazones mountain a few days ago:http://www.vancouversun.com/technology/Chilean+mountaintop+blasted+install+European+Extremely+Large/9955013/story.htmlHere is the location on Google Maps: http://goo.gl/f09i1RKS Link to comment Share on other sites More sharing options...
