Are you ready to explore the X-ray Universe?

Welcome to CLAXSON!

(Classification of X-ray Sources for Novices)

Now available in EN, FR, ES and GR!

CLAXSON is a platform that trains you to identify new objects observed in the X-ray sky with the European Space Agency X-ray telescope XMM-Newton. Be the first to find new supermassive black holes, stars, galaxies and other exotic objects in observations taken over the last 20 years, and help astronomers unravel the mysteries of the X-ray sky.
