Première place au concours d'astrophotographie 2021 de l'UAI OAE, catégorie Aurores (images fixes) : Aurore multicolore en Islande, par Marco Migliardi au nom de l'Associazione Astronomica Cortina, Italie. Les aurores sont le résultat de processus d'ionisation et d'excitation dans la haute atmosphère terrestre, causés par des particules chargées provenant du vent solaire ou d'éjections de masse coronale. Les différentes couleurs d'une aurore indiquent les espèces d'atomes et de molécules atmosphériques impliquées. La couleur la plus courante est un vert vif qui, avec le rouge profond, provient de l'oxygène atomique. Les teintes bleues, violettes et roses sont beaucoup plus rares et proviennent de l'azote moléculaire. Le reflet de l'aurore dans l'eau indique la luminosité des aurores intenses à des latitudes plus élevées. cc BY 4.0
