The James Webb Space Telescope (JWST) has a 6.5 meter wide mirror, but it is a space-based telescope, without atmosferic distortion.<br /><br />The European Extremly Large Telescope (EELT) has a 42 meter wide mirror and it is an earth-based telescope with adaptative optics (with compensates the atmospheric distortion, or part of it AFAIK)<br /><br /><br />Does anyone knows which of those is the best? why? <div class="Discussion_UserSignature"> </div>
