Constructing The World's Largest Telescope (E-ELT)
The E-ELT will have a reflecting telescope with 39.3 m diameter and a 4.2 m secondary mirror. These will be supported by adaptive optics along with several measuring and tracking instruments. The total cost of the construction of the telescope is â¬1.1 billion. Of course, the E-ELT will be able to look deeper into the space than any other astronomical instrument or tool in existence.
The extremely large telescope will play a key role in expanding our knowledge about the earliest stages of formation of planets and stars. It's expected that the E-ELT will help the researchers directly measure the rate at which Universe is expanding.
