After a brief historical review, the basic principles of telescopes will be explained. Students will have the opportunity to observe objects themselves through telescopes used by amateur astronomers. We will then discuss telescopes used by professionals: on Earth we will talk about observatories, in space about space telescopes, such as the JAMES WEBB which was launched on 25 December 2021. The precision of the images they collect is such that they allow, among other things, a better understanding of the distant origins of the Universe and the search for possible traces of life on exoplanets (planets in orbit around stars other than the Sun).
Public: 5th primary to 6th secondary
Duration: 60 minutes
Objectives: To explain in a simple way the basic principles of telescopes used by both amateur and professional astronomers. We will also review the main objectives of the JAMES WEBB telescope that was recently launched into space. This telescope should allow us to better understand the origins of the universe and the formation of galaxies and their evolution. It should also clarify the conditions for the appearance of life in solar systems other than our own.
