Description
A general overview of the physical properties of the HII regions is presented here, emphasizing the various general models made to explain their structure and behaviour. The Lyman continuum effective extinction, representing a measure of the extinguished or lost fraction of the ionizing flux, is explained briefly, and the results of a study performed on this matter are presented. This study, based on a sample of about 200 HII regions of the galaxy M51 using high resolution images acquired with the HST, suggests a highly inhomogeneous structure.

    The Large Interferometer For Exoplanets (LIFE) is a proposed space mission that enables the spectral characterization of the thermal emission of exoplanets in the solar neighborhood. The mission is designed to search for global atmospheric biosignatures on dozens of temperate terrestrial exoplanets and it will naturally investigate the diversity of
