M\u00e5ske, n\u00e5r man lever af <a href=\"http:\/\/www.esa.int\/kids\/en\/learn\/Life_in_Space\/Are_we_alone\/Exoplanets\" target=\"_blank\" rel=\"noopener\">planeter uden for solsystemet<\/a>!

Nye stjerner udsender chokb\u00f8lger ud i rummet, som f\u00e5r dette tilbagev\u00e6rende materiale til at samle sig, og med tiden danner det planeter.<\/p>\n<\/div>\n<p>Utroligt nok har vi billeder af, hvordan exoplanetsystemer dannes! De <a href=\"http:\/\/www.esa.int\/kids\/en\/learn\/Technology\/Spacecraft\/The_Hubble_Space_Telescope\" target=\"_blank\" rel=\"noopener\">NASA\/ESA\u2019s Hubble-rumteleskop<\/a> blev brugt til at unders\u00f8ge Oriont\u00e5gen, og man opdagede det, som forskerne kalder protoplanetariske skiver. Det er sandsynligvis meget unge solsystemer, der er ved at blive dannet! M\u00e5ske vil de en dag danne planeter, der p\u00e5 sigt vil v\u00e6re helt perfekte for livets udvikling.<\/p>\n<p>Ud over at opdage solsystemer under dannelse har forskerne allerede fundet tusindvis af fuldt udviklede exoplaneter, og de finder stadig flere! Mange af disse planeter kaldes \u201cvarme Jupiter-planeter\u201d, fordi de er store og har en h\u00f8j masse (ligesom <a href=\"https:\/\/www.esa.int\/kids\/en\/learn\/Our_Universe\/Planets_and_moons\/Jupiter\" target=\"_blank\" rel=\"noopener\">Jupiter<\/a> i vores eget solsystem), men kredser ogs\u00e5 meget t\u00e6t p\u00e5 deres stjerner. Det g\u00f8r det usandsynligt, at de er egnede til liv, som vi kender det, men i takt med at vores metoder til at opdage exoplaneter bliver bedre, finder vi nu ogs\u00e5 tegn p\u00e5 flere jordlignende planeter derude.<\/p>\n<p>Det er ikke kun planeter, der kredser om stjerner. Andre objekter i rummet, s\u00e5som <a href=\"https:\/\/www.esa.int\/kids\/en\/learn\/Our_Universe\/Comets_and_meteors\/Asteroids_the_minor_planets\" target=\"_blank\" rel=\"noopener\">asteroider<\/a> og <a href=\"https:\/\/www.esa.int\/kids\/en\/learn\/Our_Universe\/Comets_and_meteors\/Comets\" target=\"_blank\" rel=\"noopener\">kometer<\/a>, g\u00f8r det samme. Kunne der findes liv p\u00e5 disse? Det er mindre sandsynligt, men der er en mulighed. Nogle forskere mener, at det er muligt, at bittesm\u00e5 mikroorganismer kan blive transporteret fra planet til planet p\u00e5 stenstykker fra asteroider eller endda gennem store omr\u00e5der af rummet p\u00e5 kometer! Vi kan ikke v\u00e6re sikre, men det er en interessant tanke at overveje.<\/p>\n<p>Hvad tror du? Er der liv omkring andre stjerner?
