Construction begins on world's largest telescope in Chilean desert
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.
The size of the ELT has the potential to transform our understanding of the universe, say its backers, with its main mirror that will measure some 39 meters (43 yards) across.
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 characterize 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.

NASA's Juno Spacecraft Just Shattered What We Knew About Jupiter
Just when we thought we had Jupiter all figured out, NASA’s Juno spacecraft reveals new results that challenge almost every assumption we’ve made about the gas giant.
The first, said Juno’s principal investigator said Juno’s principal investigator from Juno’s initial two flybys back in August 2016 describe giant cyclones, a super powerful magnetic field, and weird northern lights that behave totally different to our own.
The discoveries were made when the basketball court-sized spacecraft swooped within 5,000 kilometres (3,106 miles) of the cloud tops, and drifted over the planet’s poles.
“What we’ve learned so far is Earth-shattering. Or should I say, Jupiter-shattering,” said Juno’s principal investigator at the South Research Institute, Scott Bolton. “Discoveries about its composition, magnetosphere, and poles are as stunning as the photographs the mission is generating.”
