Follow its launch in the video and ask your questions to the researchers who use it

The James Webb Space Telescope (JWST), built by the American (NASA), European (ESA) and Canadian (CSA) space agencies, will be launched on Saturday, December 25 at 1:20 p.m. At 25 square meters, its primary mirror is the largest ever sent into space, and after 29 days it will reach around Lagrange L2, 1.5 million kilometers from Earth. Often referred to as the successor to the Hubble Telescope, launched in 1990, due to the scale of the project, it may actually be quite different from its predecessor. Specially developed for infrared observation, James Webb should be able to observe the atmospheres of planets outside the Solar System and study the universe 13.7 billion years ago. , Or 100 million years after the Big Bang.

Who animates it directly?

Journalist Arthur Carpentier is hosting this live video, during which he will answer your questions. He has three speakers around him to deepen the different issues surrounding the James Webb Space Telescope. All of them have participated in its development, or will participate in its work.

Live video program

This live is divided into three main chapters as a climax of the JWST at the top of the Ariane 5 launcher, scheduled for 1:20 pm Paris time:

  • 11:00 – The beginning of live
    11 hours 15 In search of the first lights and galaxies in the universe

  • 12 hours 15 – Presentation of the James Webb Project: Understanding the Stocks of the Astronomical Event of the Decade
    With Olivier La Marley, Head of the Universal Sciences Program at the National Center for Space Studies (CNES), a French space agency.
  • 13 hours20 – Lift off!
  • 13 hours 45 – Smell the air of exoplanets and look for signs of life: how JWST disturbs our knowledge of these distant worlds
    With Frank Celsius, Director of CNRS Research at the Bordeaux Astrophysics Laboratory, specializes in the study of exoplanets’ atmospheres.
