Observer et comprendre l'Univers

Who are we ?

IRAP teams work on the study and understanding of the Universe and its content: the Earth as a planet, its ionized spatial environment, the sun and its planets, the stars and their planetary systems, the interstellar environment, galaxies, compact objects, the very first stars and the primordial Big Bang.
This is done through observation, modeling and theory, instrumentation and laboratory experiments.

With a staff of technical personnel qualified in the field of design, construction, integration and operation of instruments on the ground and in space, IRAP is a major center of instrumentation in astrophysics , at an international level. He also participates in numerous national observation services (SNO) of INSU.
