or European Extremely Large telescope. With a mirror that is 39 metres (128ft) in diameter, the E-ELT will dwarf all existing optical telescopes
Hence it takes an extremely large telescope to try to spot any planets that may support alien life many light years away.
#or Very Large telescope, composed of four individual 8. 2m (26. 9ft) mirrors#based at Cerro Paranal,
For the new study published in the Monthly Notices of the Royal Astronomical Society researchers used the Very Large telescope in Chile
and the large telescopes of the W. M. Keck Observatory researchers found an excess of oxygenâ##a chemical signature that indicates that the debris had once been part of a bigger body originally composed of 26 percent water by mass.
they used the Southern African Large telescope to gather data to help determine the size of the black hole.
The data from that study, using the ESO Very Large telescope in Chilie, seemed to indicate that water persisted on the surface of the Red planet for at least a billion years.

In astronomy, it will boost the performance of adaptive optics, a technology at the heart of the European Extremely Large telescope (E-ELT.
