| contents | The EXO-UV program is an international, interdisciplinary collaboration between astrophysicists and biologists aimed at expanding the characterization of ultraviolet radiation (UVR) environments on exoplanets. This approach combines astrophysical studies with biological experiments to better understand the potential impacts of UVR on exoplanetary surfaces. UVR is particularly relevant because it reaches the surface of planets and can influence their habitability. The specific wavelengths within the UVR spectrum depend on the planet's atmospheric composition and the spectral energy distribution of its host star. Additionally, high UVR fluxes emitted during flares and superflares are of particular interest due to the limited information available regarding their biological impact. The EXO-UV program has successfully led to the first experimental study examining the biological effects of high UVR fluences, such as those produced by flares and superflares. Future experimental studies aim to investigate the biological effects of repetitive flares. In this paper, we review the latest results from our EXO-UV program. |
