Om du aldrig tidigare har sett en meteor \u00e4r detta det perfekta tillf\u00e4llet. Sv\u00e4rmet p\u00e5g\u00e5r fr\u00e5n slutet av juli till den 20 augusti, och den st\u00f6rsta aktiviteten f\u00f6rv\u00e4ntas mellan den 11 och 13 augusti. Himlen kommer att vara m\u00f6rk, eftersom m\u00e5nsk\u00e4ran g\u00e5r ner under horisonten mitt p\u00e5 kv\u00e4llen. Och natten b\u00f6r dessutom bli varm, s\u00e5 du beh\u00f6ver inte ens kl\u00e4 dig varmt! H\u00e5ll dig bara borta fr\u00e5n starkt ljus, l\u00e5t \u00f6gonen v\u00e4nja sig vid m\u00f6rkret och l\u00e4gg dig sedan ner och blicka upp mot himlen.<\/p>\n<\/div>\n<figure class=\"wp-block-image size-natural\" data-width=\"550\" data-credit=\"NASA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2013\/07\/perseid_map2\" 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\/2013\/07\/perseid_map2\/17878589-2-eng-GB\/perseid_map2.gif\" alt=\"\"><\/figure>\n<p>Perseiderna har f\u00e5tt sitt namn efter stj\u00e4rnbilden Perseus, fr\u00e5n vilken de tycks str\u00e5la ut.

Det b\u00e4sta st\u00e4llet att titta \u00e4r d\u00e4r himlen \u00e4r som m\u00f6rkast, troligen rakt upp. Stj\u00e4rnbilden ligger l\u00e5gt i nord-nordost f\u00f6re midnatt och stiger h\u00f6gre \u00f6ver horisonten under de tidiga morgontimmarna. Meteorregnet kan b\u00e4st observeras fr\u00e5n kl. 23 eller midnatt och fram\u00e5t, d\u00e5 man kan se 60\u2013100 meteorer per timme.<\/p>\n<p>Perseiderna \u00e4r sand- till \u00e4rtstora bitar av stenavfall som f\u00f6r l\u00e4nge sedan slungades ut av kometen Swift-Tuttle. Kometen faller l\u00e5ngsamt s\u00f6nder medan den kretsar kring solen. Under \u00e5rhundradenas lopp har dess s\u00f6nderfallna rester spridit sig l\u00e4ngs dess bana och bildat ett partikelstr\u00f6m som \u00e4r hundratals miljoner kilometer l\u00e5ngt.<\/p>\n<p>Jordens bana runt Solen f\u00f6r oss genom detta kometavfall varje \u00e5r i mitten av augusti. Partiklarna, eller meteoroiderna, r\u00f6r sig med en hastighet av 60 km per sekund i f\u00f6rh\u00e5llande till Jorden. N\u00e4r en av dem tr\u00e4ffar den \u00f6vre atmosf\u00e4ren skapar den ett gl\u00f6dande sp\u00e5r av \u00f6verhettad luft. Enstaka ljusare partiklar kan finnas kvar i flera sekunder och l\u00e4mna efter sig kortlivade sp\u00e5r av gl\u00f6dande r\u00f6k och gas.<\/p>\n<p>Perseiderna \u00e4r perfekta f\u00f6r digital fotografering.
