The Investigation:

Is it possible that life exists elsewhere than on Earth?
It’s up to you to lead the investigation…

13 stages in which adults can lead the investigation and children can complete a game-mission.

The adult investigation

Use the investigation booklet that you are given on your arrival to explore the 13 stages of the exhibition.

Investigate

Pick up a clue at each stage and work out whether or not it supports the theory that extraterrestrial life exists.

Find out

At the end of the circuit, collect your clues together and find out what we can really think today about the possibility of extraterrestrial life…

The Junior game-mission (from age 8)

The ARC has specially prepared 13 puzzles for you that you’ll have to solve during your visit to the Cité de l’Espace.

Solve the 13 puzzles

At each stage: touch, listen and look carefully around you to find the right answer.

Log on to the Internet

At the end of the day, use your computer to log on to the ARC Junior page and enter your 13 solutions.

Become a member of the A.R.C. (Alien Research Centre)

If you find the right answers, you can open the ARC’s secret files and earn the right to help real astronomers to detect Extraterrestrials.
