Hun geboorteplaatsen zijn enorme, koude wolken van gas en stof, die \u2018nevels\u2019 worden genoemd. De bekendste daarvan is de Orionnevel, die net met het blote oog zichtbaar is.<\/p>\n<\/div>\n<p>Naarmate de wolk kleiner wordt, valt ze in brokken uiteen. Elke brok wordt uiteindelijk zo heet en compact dat er kernreacties op gang komen. Als de temperatuur tien miljoen graden Celsius bereikt wordt de klomp een nieuwe ster.<\/p>\n<p>Na hun geboorte liggen de meeste jonge sterren in het midden van een platte schijf van gas en stof. Het meeste van dat materiaal wordt uiteindelijk weggeblazen door de straling van de ster. Voordat het zover is, kunnen er rondom de ster planeten worden gevormd.<\/p>\n<figure class=\"wp-block-image size-natural\" data-width=\"400\" data-credit=\"ESA\/ISO, CEA Saclay and ISOCAM Consortium\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/1998\/01\/Star-forming_dark_cloud_imaged_by_ISO2\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/1998\/01\/star-forming_dark_cloud_imaged_by_iso2\/17863159-3-eng-GB\/Star-forming_dark_cloud_imaged_by_ISO.jpg\" alt=\"Star-forming dark cloud imaged by ISO\"><figcaption>Door ISO gefotografeerde donkere wolk waarin sterren ontstaan<\/figcaption><\/figure>\n<p>Infraroodobservatoria kunnen warmte waarnemen die afkomstig is van onzichtbare sterren die zich binnen dergelijke wolken vormen.
