James Webb Space Telescope reaches final stop 1 million miles from Earth
- The US$10 billion observatory is now in place in orbit around the sun as it prepares to give scientists a look at the dawn of the universe
- Besides making stellar observations, Webb will scan the atmospheres of alien worlds for possible signs of life
The world’s biggest, most powerful space telescope arrived at its observation post 1 million miles from Earth on Monday, a month after it lifted off on a quest to behold the dawn of the universe.
On command, the James Webb Space Telescope fired its rocket thrusters for nearly five minutes to go into orbit around the sun at its designated location, and Nasa confirmed the operation went as planned.
The mirrors on the US$10 billion observatory still must be meticulously aligned and the infrared detectors sufficiently chilled before science observations can begin in June. But flight controllers in Baltimore were euphoric after chalking up another success.
“We’re one step closer to uncovering the mysteries of the universe. And I can’t wait to see Webb’s first new views of the universe this summer!” Nasa Administrator Bill Nelson said in a statement.
The telescope will enable astronomers to peer back further in time than ever before, all the way back to when the first stars and galaxies were forming 13.7 billion years ago. That’s a mere 100 million years from the Big Bang, when the universe was created.
Besides making stellar observations, Webb will scan the atmospheres of alien worlds for possible signs of life.
