After a succession of postponements, the James Webb space telescope, the largest and most powerful ever sent into space, will be launched from Kourou (Guyana) on Friday 24 December
The James Webb telescope, at 12 meters high, is the largest and most advanced ever to be sent to space. It is the result of three decades of collaboration between scientists around the world. Mark Voyton, NASA director of the James Webb program, worked on the telescope for 20 years. “Every time I look at him I’m in awe, really in awe of his beauty. He’s so complex, can do so many beautiful things. He’s been built on Earth, but he’s going to tell us everything we can’t. not yet know about the universe “, explains the scientist.
The James Webb will go four times farther than the moon, at Lagrange 2, 1.5 million kilometers from Earth. At this precise location, the telescope can revolve around the sun without moving away from our planet. It will be able, thanks to infrared technology, to track exoplanets, black holes and the first galaxies. “We know that the universe is 12.5 billion years old. Before, when everything took shape, we have no idea. So it’s the organs of our universe that we are going to look for”, says Peter Jensen, former director of the James Webb program at ESA (European Special Agency).
