Abstract
Dentro de los numerosos factores que influyen en la habitabilidad de un planeta, la presencia de una atmósfera es un elemento crucial para el sustento de la vida. No obstante, la atmósfera de un planeta como la Tierra, lejos de ser estática, es un sistema en constante evolución, con cambios significativos en su composición y propiedades a lo largo de su existencia. La detección y caracterización tanto de planetas extrasolares, así como la observación de la Tierra revela la existencia de amplias envolturas compuestas fundamentalmente por hidrógeno, correspondientes a diferentes etapas evolutivas del planeta. Debido a su significativa extensión, son susceptibles de ser detectadas a través de trazadores espectroscópicos en longitudes de onda en el rango ultravioleta...

However, the atmosphere of a planet such as Earth, is far from being static; it is a system in constant evolution, with significant changes in its composition and properties throughout its existence. The detection and characterization of planets beyond our Solar System, as well as observation of the Earth, reveal the presence of extended hydrogen atmospheres around these planets, albeit at differente volutionary stages. Given their significant extension, these gaseous envelopes are susceptible to be detected using spectroscopic tracers in ultraviolet wavelengths...
