Salamoista on viel\u00e4 paljon, mit\u00e4 emme ymm\u00e4rr\u00e4, mutta er\u00e4\u00e4n ESA:n astronautin kokemus on antanut tutkijoille paljon pohdittavaa.<\/p>\n<\/div>\n<p>Astronautti oli Andreas Mogensen, joka oli kansainv\u00e4lisell\u00e4 avaruusasemalla vuonna 2015. Kun h\u00e4n oli kiertoradalla lent\u00e4m\u00e4ss\u00e4 Intian yl\u00e4puolella, h\u00e4n suuntasi huipputeknisen kameran kohti valtavaa ukkosmyrsky\u00e4, jonka h\u00e4n n\u00e4ki alapuolellaan. Andreas havaitsi sinisen suihkun, joka ampaisi yl\u00f6sp\u00e4in maapallon ilmakeh\u00e4n yl\u00e4kerroksiin. Se nousi 40 kilometrin korkeuteen \u2013 yli nelj\u00e4 kertaa niin korkealle kuin Mount Everest!<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"781\" data-credit=\"Terma\/DTU\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2018\/04\/Atmosphere-Space_Interactions_Monitor\" 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\/2018\/04\/atmosphere-space_interactions_monitor\/17892427-2-eng-GB\/Atmosphere-Space_Interactions_Monitor.jpg\" alt=\"Atmosphere-Space Interactions Monitor\"><figcaption>Ilmakeh\u00e4n ja avaruuden v\u00e4listen vuorovaikutusten seurantalaite<\/figcaption><\/figure>\n<p>T\u00e4m\u00e4 upea videomateriaali oli ensimm\u00e4inen laatuaan.
