  Science Fiction is using astronomy to offer to the public blockbusters at the
movies (e.g. Interstellar), series or movies in streaming media (Don't Look Up,
The Expanse), many books from classic authors (I. Asimov, A.C. Clarke) or more
modern ones (K.S. Robinson), comics (the adventures of Valerian and Laureline),
or video games (Mass Effect, No Man's sky) that have a very large cumulated
audience. Astronomers can use Science Fiction to illustrate physics or
astronomical facts. It might be a good way to talk about our work, our methods,
by comparing them to examples with which a large audience is familiar. A few
examples are provided in this contribution. In a recent study (Stanwey, 2022),
it was shown that 93 percent of British professional astronomers have an
interest for Science Fiction, and 69 percent consider that Science Fiction
influenced their career or life choice. I am presenting a similar study made
for French astronomers, performed during and just after the 2024 French
astronomer meeting (Journees de la SF2A).
