Follow its release on video and ask your questions to the researchers who use it

Built by the James Webb Space Telescope (JWST), US (NASA), European (ESA) and Canada (CSA) space agencies, it is scheduled to take off on Saturday, December 25 at 1:20 p.m. With its primary mirror area of ​​25 square meters, it is the largest ever sent into space, and after 29 days it will orbit the Lockrange L2 at a distance of 1.5 million kilometers from Earth. It was often said that he was the successor to the Hubble Telescope, which was launched in 1990, and due to the size of the project, it would actually be completely different from its predecessor. James Webb, who was created to observe infrared rays, wants to make it possible to observe the atmospheres of planets outside the solar system, but also to explore the universe as it did 13.7 billion years ago.

Who is animating this directly?

Journalist Arthur Carpentier hosts this live video and he answers your questions. Three speakers surround him to deepen different things around the James Web Space Telescope. All of them have participated in its development, or will participate in its operation.
