Claude TrudelUne myriade de trous noirs stellaires autour de Sgr A* ⭐ Une équipe de chercheurs vient de trouver une preuve de la présence d'une grande population de trous noirs stellaires qui se trouveraient tout autour de Sgr A* et qui ont pour effet de détruire les grosses étoiles de son voisinage le plus proche en quelques millions d'années.

Florian LaunetteI was lucky enough to be able to photograph the Tsuchinshan-ATLAS comet with the Milky Way above a termite mound during a trip to Botswana. It was simply magical. How did I take this photo? Canon R3 Sigma 20 mm Art F1.4. ISO 3200 30' F2.8 with tripod. I tried to keep it simple and I like the result which remains accessible in terms of making it. J'ai eu la chance de pouvoir photographier la comète Tsuchinshan-ATLAS avec la voie lactée au dessus d'une termitière lors d'un voyage au Bostwana. C'était tout simplement ...magique ! Comment ai je fait cette photo ? canon R3 Sigma 20 mm Art F1,4. iso 3200 30' F2,8 avec trépied. j'ai essayé de faire simple et j'aime bien le résultat qui reste accessible en termes de réalisation. <a href="https://pixelfed.social/discover/tags/nature?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#nature</a> <a href="https://pixelfed.social/discover/tags/stars?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#stars</a> <a href="https://pixelfed.social/discover/tags/milkyway?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#milkyway</a> <a href="https://pixelfed.social/discover/tags/astrophotography?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#astrophotography</a> <a href="https://pixelfed.social/discover/tags/atlas?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#atlas</a> <a href="https://pixelfed.social/discover/tags/art?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#art</a> <a href="https://pixelfed.social/discover/tags/africa?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#africa</a> <a href="https://pixelfed.social/discover/tags/bostwana?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#bostwana</a> <a href="https://pixelfed.social/discover/tags/wildlife?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#wildlife</a> <a href="https://pixelfed.social/discover/tags/sky?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#sky</a> <a href="https://pixelfed.social/discover/tags/night?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#night</a> <a href="https://pixelfed.social/discover/tags/basic?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#basic</a> <a href="https://pixelfed.social/discover/tags/sigma?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#sigma</a> <a href="https://pixelfed.social/discover/tags/canon?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#canon</a> <a href="https://pixelfed.social/discover/tags/nightsky?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#nightsky</a> <a href="https://pixelfed.social/discover/tags/ciel?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#ciel</a> <a href="https://pixelfed.social/discover/tags/astro?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#astro</a> <a href="https://pixelfed.social/discover/tags/voielactee?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#voielactee</a> <a href="https://pixelfed.social/discover/tags/comete?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#comete</a> <a href="https://pixelfed.social/discover/tags/atlas?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#atlas</a> <a href="https://pixelfed.social/discover/tags/afrique?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#afrique</a> <a href="https://pixelfed.social/discover/tags/travel?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#travel</a> <a href="https://pixelfed.social/discover/tags/photography?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#photography</a> <a href="https://pixelfed.social/discover/tags/animal?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#animal</a> <a href="https://pixelfed.social/discover/tags/animals?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#animals</a> <a href="https://pixelfed.social/discover/tags/science?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#science</a> <a href="https://pixelfed.social/discover/tags/Tsuchinshan?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#Tsuchinshan</a>
