Exoplanetas habitables

Los exoplanetas habitables orbitan en la zona habitable de su estrella, donde puede existir agua líquida. La distancia determina la temperatura: como en nuestro sistema solar, Mercurio es abrasador, Marte es helado y la Tierra está en el punto ideal. El agua líquida requiere temperaturas de 0 a 100 °C con la presión atmosférica adecuada. La composición química es igual de clave: se necesita una superficie rocosa y una atmósfera rica en carbono, hidrógeno, oxígeno y nitrógeno, pilares esenciales para la vida.

Image: Variable X-ray radiation likely drives helium escape from exoplanet LHS 1140 b
LHS 1140 b is a rocky planet orbiting within the habitable zone of a Red dwarf star. Previous observations detected helium escaping from the planet as it transited, or passed in front of, its host star. Because stars emit high-energy radiation that can strip away planetary atmospheres, researchers analyzed whether fluctuations in the star's X-ray and ultraviolet output could explain the changing levels of escaping helium. Using the XMM-Newton space telescope, observers monitored the system fo...

Image: Escaping helium atmosphere identified on the rocky exoplanet LHS 1140b
Spectroscopic observations reveal helium escaping from the atmosphere of rocky exoplanet LHS 1140b. Data from 2024 and 2025 show this process is time-variable, suggesting an atmosphere depleted of hydrogen. No such escape was detected on the companion planet LHS 1140c....
