Large Binocular Telescope (LBT) has become active now and is operating at full power from a remote mountaintop in Arizona.It took $120m and 20 years to make Large Binocular Telescope. It consists of two mirrors, each of which is 27 feet in diameter and weighs more than 35000 pounds. These large mirrors give Large Binocular Telescope equivalent resolution of 75 feet. The resolution of LBT is 10 times greater than that of Hubble telescope which has 8 feet mirror.

On 6th March 2006,scientists working on LBT released striking images of a spiral galaxy which is 102 million light years away. These pictures were taken when second of the two mirrors went operational.

Scientist believe that with the help of LBT, they will be able to discover new planets and stars. It will be also useful in knowing more about our solar system and distant galaxies.
