Njihova rojstna mesta so ogromni, hladni oblaki plina in prahu, znani kot \u2018meglice\u2019. Najbolj znana med njimi je Orionova meglica, ki jo je mogo\u010de komajda videti s prostim o\u010desom.<\/p>\n<\/div>\n<p>Ti oblaki se za\u010dnejo kr\u010diti pod vplivom lastne gravitacije. Ko se oblak skr\u010di, se razdeli na skupke. Vsak skupek s\u010dasoma postane tako vro\u010d in gost, da se v njem za\u010dnejo jedrske reakcije. Ko temperatura dose\u017ee 10 milijonov stopinj Celzija, se skupek spremeni v novo zvezdo.<\/p>\n<p>Po nastanku se ve\u010dina mladih zvezd nahaja v sredi\u0161\u010du plo\u0161\u010datega diska iz plina in prahu. Ve\u010dino tega snovi s\u010dasoma odpihne sevanje zvezde. Preden se to zgodi, se lahko okoli osrednje zvezde oblikujejo planeti.<\/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>Temni oblak, v katerem nastajajo zvezde, posnet s teleskopom ISO<\/figcaption><\/figure>\n<p>Infrarde\u010di observatoriji lahko zaznavajo toploto, ki izhaja iz nevidnih zvezd, ki nastajajo znotraj tak\u0161nih oblakov.
