Construction begins on the world’s first ‘super telescope’ that could help astronomers find alien life

  • The European Extremely Large Telescope is due to begin operating in 2024 
  • The telescope is on a 3,000 meter-high mountain in Chile’s Atacama desert
  • It will refine astronomers’ burgeoning discoveries of planets orbiting stars
  • It is some five times larger than the top observing instruments in use today

Construction has begun on a ‘super telescope’ that could help astronomers find alien life.

The  European Extremely Large Telescope (E-ELT), being built in Chile, is designed to help astronomers peer back to the first galaxies 14 billion years ago.

When its completed, it will be the world’s largest optical telescope, some five times larger than the top observing instruments in use today.

THE ELT: KEY FACTS

The Extremely Large Telescope (ELT), will be the world’s largest optical telescope.

It will be some five times larger than the top observing instruments in use today.

Its main mirror will measure some 39 meters (127ft) across.

This will give it the ability to find more smaller planets, image larger ones, and possibly characterise their atmosphere

Located on a 3,000 meter-high mountain in the middle of the Atacama desert, it is due to begin operating in 2024.

The size of the ELT has the potential to transform our understanding of the universe, say its backers.

Its main mirror will measure some 39 meters (127ft) across.

This will be housed in an huge rotating dome 85 metres in diameter – a similar size to a football pitch.

Located on a 3,000 meter-high mountain in the middle of the Atacama desert, it is due to begin operating in 2024.

Among other capabilities, it will add to and refine astronomers’ burgeoning discoveries of planets orbiting other stars, with the ability to find more smaller planets, image larger ones, and possibly characterise their atmospheres, a key step in understanding if life is present.

‘What is being raised here is more than a telescope. Here we see one of the greatest examples of the possibilities of science,’ said Chilean President Michelle Bachelet in a speech to mark the beginning of construction at the site.

The dry atmosphere of the Atacama provides as near perfect observing conditions as it is possible to find on Earth, with some 70 percent of the world’s astronomical infrastructure slated to be located in the region by the 2020s.

The ELT is being funded by the European Southern Observatory, an organisation consisting of European and southern hemisphere nations.

Construction costs were not available but the ESO has said previously that the ELT would cost around 1 billion euros ($1.12 billion, £871 million) at 2012 prices.
