Some crustaceans and deep sea fish also have…

Construction begins on world’s largest telescope in Chile

SANTIAGO: Construction began in Chile on Friday on the European Extremely Large Telescope, which when completed will be the world's largest optical telescope, some five times larger than the top observing instruments in use today.

Once fully operational, FAST will be able to…
