Operational for a year and a half, the James Webb space telescope has already made it possible to admire splendid images of the universe and to collect in particular valuable data on extrasolar planets, those which revolve around stars other than the Sun.

Then because, in the opinion of some, James Webb would not be powerful enough to find life outside the Solar System.
