Det handlar troligen om mycket unga solsystem som h\u00e5ller p\u00e5 att bildas! Kanske kommer de en dag att bilda planeter som s\u00e5 sm\u00e5ningom kommer att vara precis r\u00e4tt f\u00f6r att liv ska kunna utvecklas.<\/p>\n<p>F\u00f6rutom att uppt\u00e4cka solsystem under utveckling har forskarna redan hittat tusentals fullt utvecklade exoplaneter, och de forts\u00e4tter att uppt\u00e4cka fler! M\u00e5nga av dessa planeter kallas \u201cheta Jupiter-planeter\u201d eftersom de \u00e4r stora och har en h\u00f6g massa (precis som <a href=\"https:\/\/www.esa.int\/kids\/en\/learn\/Our_Universe\/Planets_and_moons\/Jupiter\" target=\"_blank\" rel=\"noopener\">Jupiter<\/a> (i v\u00e5rt eget solsystem), men kretsar ocks\u00e5 mycket n\u00e4ra sina stj\u00e4rnor. Detta skulle g\u00f6ra det osannolikt att de \u00e4r l\u00e4mpliga f\u00f6r liv s\u00e5 som vi k\u00e4nner till det, men i takt med att v\u00e5ra metoder f\u00f6r att uppt\u00e4cka exoplaneter f\u00f6rb\u00e4ttras hittar vi nu \u00e4ven tecken p\u00e5 fler jordliknande planeter d\u00e4r ute.<\/p>\n<p>Det \u00e4r inte bara planeter som kretsar kring stj\u00e4rnor. Andra objekt i rymden, till exempel <a href=\"https:\/\/www.esa.int\/kids\/en\/learn\/Our_Universe\/Comets_and_meteors\/Asteroids_the_minor_planets\" target=\"_blank\" rel=\"noopener\">asteroider<\/a> och <a href=\"https:\/\/www.esa.int\/kids\/en\/learn\/Our_Universe\/Comets_and_meteors\/Comets\" target=\"_blank\" rel=\"noopener\">kometer<\/a>, g\u00f6r detsamma. Kan det finnas liv p\u00e5 dessa? Det \u00e4r mindre troligt, men det finns en m\u00f6jlighet. Vissa forskare anser att det \u00e4r m\u00f6jligt att sm\u00e5 mikroorganismer kan transporteras fr\u00e5n planet till planet p\u00e5 stenblock fr\u00e5n asteroider, eller till och med \u00f6ver stora avst\u00e5nd i rymden p\u00e5 kometer! Vi kan inte vara s\u00e4kra, men det \u00e4r en intressant tanke att fundera \u00f6ver.<\/p>\n<p>Vad tror du? Finns det liv kring andra stj\u00e4rnor?
