Este nuevo hallazgo marca la primera vez que el Webb descubre un planeta fuera del sistema solar mediante im\u00e1genes directas.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">El exoplaneta, un gigante gaseoso del tama\u00f1o aproximado de Saturno, orbita la estrella TWA 7, situada a unos 110 a\u00f1os luz de la Tierra en la constelaci\u00f3n de Antlia. Su distancia orbital es unas 52 veces mayor que la de la Tierra al Sol, lo que lo convierte en un objetivo inaccesible para los m\u00e9todos de detecci\u00f3n m\u00e1s comunes, como el tr\u00e1nsito.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A diferencia del 98% de los casi 5900 exoplanetas descubiertos hasta ahora \u2014identificados por m\u00e9todos indirectos\u2014, este planeta fue captado directamente gracias a un coron\u00f3grafo instalado en el instrumento de infrarrojo medio (MIRI) del telescopio Webb. Este dispositivo bloquea la intensa luz estelar, permitiendo ver objetos tenues cercanos.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">El hallazgo es relevante porque se trata del planeta menos masivo jam\u00e1s captado con im\u00e1genes directas, con una masa diez veces menor que la del anterior r\u00e9cord en esta categor\u00eda. \u201cWebb abre una nueva ventana a exoplanetas que hasta ahora no hab\u00edan sido observables\u201d, explic\u00f3 la astr\u00f3noma Anne-Marie Lagrange, autora principal del estudio publicado en la revista Nature.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Tanto la estrella TWA 7 como su planeta tienen una edad estimada de apenas 6 millones de a\u00f1os, lo que proporciona una valiosa oportunidad para estudiar las primeras etapas de formaci\u00f3n de sistemas planetarios. Desde la perspectiva casi vertical de observaci\u00f3n, los cient\u00edficos tambi\u00e9n han identificado en el sistema un disco protoplanetario con estructuras en forma de anillo, lo que podr\u00eda revelar m\u00e1s sobre la evoluci\u00f3n planetaria.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Aunque a\u00fan no se conoce la composici\u00f3n de la atm\u00f3sfera del exoplaneta, futuras observaciones podr\u00edan arrojar m\u00e1s datos. Sin embargo, Webb todav\u00eda no es capaz de obtener im\u00e1genes directas de exoplanetas rocosos del tama\u00f1o de la Tierra, que son los m\u00e1s prometedores en la b\u00fasqueda de vida.<\/span><\/p>\n<p><b>Redacci\u00f3n de: <\/b><span style=\"font-weight: 400;\">Karen Rodr\u00edguez A.<\/span><\/p>","protected":false},"excerpt":{"rendered":"<p>El Telescopio Espacial James Webb, lanzado en 2021, no solo ha revolucionado la observaci\u00f3n del universo primitivo, sino que ahora ha logrado captar directamente la imagen de un exoplaneta nunca antes registrado.
