       |  _It has around 250 times the light gathering area of the Hubble
       | Space Telescope and, according to the ELT 's specifications,
       | would provide images 16 times sharper than those from Hubble._

       | Edit: Wow, this construction image from August:

         | Extremely Large Telescope is the budget version.

         | The original plan was Overwhelmingly Large Telescope

       | Tom Scott did a video on the ELT about a month ago:

       | * https://www.youtube.com/watch?v=QqRREz0iBes
       | 
       | Most of the video is an explanation of (a) why ground-based
       | telescopes are still useful, and (b) why ganging up multiple
       | telescopes (to create a large 'virtual' area) only goes so far,
       | and then he gets into the ELT in part three of the video.
       | 
       | It's big. The scale is remarkable.

         | 39.3m aperture, mirror area scales quadratically with that

       | Tom Scott recently posted a great, 30-minute video about this
       | telescope. Highly recommended.
