The James Webb Space Telescope, the world’s largest telescope, rises in a circle | Weather News
The $ 9bn observatory seeks out the slightest illumination from the first stars and galaxies, and provides an overview of the cosmos.
The world’s largest and most powerful telescope has become increasingly keenly interested in seeing light from the first stars and galaxies and in observing the universe in search of life.
NASA’s James Webb Space Telescope took off from French Guiana on the northeast coast of the United States, boarding a European Ariane rocket high on Saturday morning.
The $ 9bn viewing site was disrupted at a distance of 1.6 million miles (1 million miles) – or more than four times a month. It will take one month to get there and another five months before his infrared eyes get ready to look at the sky.
First, a large telescope mirror and a sunscreen should be exposed; folded in the shape of an origami to fit into the nose of a rocket. Otherwise, the spectacle will not be able to look back 13.7 billion years as expected, within just 100 million years from the Big Bang that created the universe.
“It will help us better understand our environment and our place in it: who we are, who we are, the ongoing search,” NASA astronaut Bill Nelson said earlier this week.
But he warned: “If you want a great reward, you must always do great harm.”
A report from Kourou, French Guiana, by Manuel Rapalo of Al Jazeera, states that the work of history that “changed the universe” “allows scientists to look back to the very beginning of our universe.”
“Scientists should also be able to look at the planets’ atmosphere and see if the planets could not be inhabited and fit for human rule over the same day, but to determine whether the conditions are right for life,” he said. he said.
‘Launch for Humanity’
Eager to replace the old Hubble Space Telescope, the long-awaited James Webb was named NASA astronaut in the 1960s. NASA has partnered with European and Canadian corporations to design and launch a new 7-ton telescope, with thousands of people from 29 countries working since the 1990s.
All over the world, astronomers waited anxiously to see Webb flee after years of failure. The last-minute hurdles disrupted the set-up for about a week, after which a hurricane pushed Christmas.
“We’re starting people this morning,” Arianespace chief Stephane Israel said just minutes before he was to leave. “After Webb, we will never see the sky again.”
Klaus Pontipiddan, one of the scientists who participated in the Webb Project, told Al Jazeera of Baltimore, US that it was “a wonderful start”.
“It was great to see everything go smoothly,” he said. “We hope that we can now see the first galaxies made in the atmosphere some 13 and a half billion years ago.”

At 21 and 14 meters (70 and 46 feet), and the size of a tennis court.
If all goes well, the solar screen will open three days after departure, at least five days for exposure and closure. Then, the glass sections should be opened like the leaves of a dripping table, 12 days or so.
Overall, hundreds of output systems must work perfectly in order for the telescope to function properly. “Like nothing we have ever done before,” said NASA program director Greg Robinson.
