L’exploraci\u00f3 de l’espai pot passar d’un somni lluny\u00e0 a un de m\u00e9s proper. La idea de trobar altres mons on la vida podria ser una opci\u00f3 \u00e9s un dels reptes de la ci\u00e8ncia actual. Gr\u00e0cies a les missions dels telescopis espacials com Kepler i el James Webb la ci\u00e8ncia ha avan\u00e7at i han pogut veure exoplanetes on la vida podria ser una possibilitat. <\/span><\/p>\n

Qu\u00e8 \u00e9s un exoplaneta?<\/strong><\/p>\n

\u00c9s un planeta fora del nostre sistema solar. De moment, hi ha confirmats quasi quatre mil exoplanetes.<\/p>\n

\"\"<\/a><\/p>\n

Alguns exemples d’avan\u00e7os que han perm\u00e8s veure exoplanetes s\u00f3n:<\/span><\/p>\n

La Mission Kepler:<\/b> el telescopi espacial Kepler va ser llan\u00e7at per la NASA l’any 2009 va descobrir m\u00e9s de 2.600 exoplanetes, molts dels quals es troben en la zona habitable de les seves estrelles. Aquesta zona on la temperatura \u00e9s adequada i permet l’exist\u00e8ncia d’aigua l\u00edquida, ingredient considerat molt important, \u00e9s un avantatge per poder crear vida.<\/span><\/p>\n

Telescopi James Webb:<\/b> el telescopi espacial anomenat James Webb Space Telescope o m\u00e9s conegut com a JWST va ser llan\u00e7at el 2021, i la bona tecnologia va permetre aprofundir encara m\u00e9s en l’estudi d’exoplanetes, No va ser nom\u00e9s capa\u00e7 de detectar planetes, sin\u00f3 tamb\u00e9 va poder analitzar les seves atmosferes amb un nivell de detall molt m\u00e9s millorat.<\/span><\/p>\n

Els criteris que tenen en compte per poder habitar un exoplaneta s\u00f3n els seg\u00fcents:<\/span><\/p>\n

-Zona habitable:<\/b> Si est\u00e0 a una dist\u00e0ncia adequada a la seva estrella.<\/span><\/p>\n

-Massa i grand\u00e0ria: <\/b>Ha de tenir massa suficient per mantenir una atmosfera. Els planetes massa petits perderen la seva atmosfera i els planetes massa grans podrien ser gasosos.<\/span><\/p>\n

-Composici\u00f3 atmosf\u00e8rica: <\/b>Uns an\u00e0lisis de es atmosferes podrien permetre als cient\u00edfics saber si la composici\u00f3 de l’atmosfera sigui adequada per a la vida.<\/span><\/p>\n

-Estabilitat orbital: <\/b>Ha de tenir una \u00f2rbita estable al llarg de milers o milions d’anys, all\u00ed les condicions per al desenvolupament de la vida sigui constant.<\/span><\/p>\n

-Un dels descobriments m\u00e9s interessants dels \u00faltims anys:<\/b> el sistema TRAPPIST-1, que cont\u00e9 exoplanetes que orbiten al voltant d’una estrella nana a uns 40 anys de llum de la Terra. Encara no se sap amb certesa si podrien suportar vida.<\/span><\/p>\n

-Un altre exoplaneta destacat: <\/b>Pr\u00f2xima Centauri b, situada a uns 4,24 anys llum de la Terra. Per\u00f2 aquesta zona habitable rep alts nivells de redacci\u00f3, aix\u00f2 va generar dubtes sobre si podria haver-hi vida.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
