THE WORLD THIS WEEK: Biggest telescope

One of the biggest telescopes in the world is being tested to take its first peek at the Universe’s hidden secrets. The Great Canary telescope has taken seven years to build, on a mountain on La Palma in the Canary Islands. It’s not quite finished but is expected to be fully operational within the next year. The optical telescope’s main mirror is a massive 10.4m wide and made up of 36 separate mirror segments. Its size will mean it can catch some of the most far away lights in the Universe which could help resea-rchers find the secrets of star fo-rmation and hunt for other planets that are like Earth.
