Its tangled filaments and shockwaves reveal the violent death of a massive star. Astronomers study it to learn how supernovae shape galaxies. We just admire it! ;-)<br />\n<br />\n<a href=\"https://pixelfed.social/discover/tags/stargazing?src=hash\" title=\"#stargazing\" class=\"u-url hashtag\" rel=\"external nofollow noopener\">#stargazing</a> <a href=\"https://pixelfed.social/discover/tags/lookup?src=hash\" title=\"#lookup\" class=\"u-url hashtag\" rel=\"external nofollow noopener\">#lookup</a> <a href=\"https://pixelfed.social/discover/tags/darksky?src=hash\" title=\"#darksky\" class=\"u-url hashtag\" rel=\"external nofollow noopener\">#darksky</a> <a href=\"https://pixelfed.social/discover/tags/astrophotography?src=hash\" title=\"#astrophotography\" class=\"u-url hashtag\" rel=\"external nofollow noopener\">#astrophotography</a> <a href=\"https://pixelfed.social/discover/tags/camping?src=hash\" title=\"#camping\" class=\"u-url hashtag\" rel=\"external nofollow noopener\">#camping</a> <a href=\"https://pixelfed.social/discover/tags/seestar?src=hash\" title=\"#seestar\" class=\"u-url hashtag\" rel=\"external nofollow noopener\">#seestar</a> <a href=\"https://pixelfed.social/discover/tags/connectwithnature?src=hash\" title=\"#connectwithnature\" class=\"u-url hashtag\" rel=\"external nofollow noopener\">#connectwithnature</a> <a href=\"https://pixelfed.social/discover/tags/sky?src=hash\" title=\"#sky\" class=\"u-url hashtag\" rel=\"external nofollow noopener\">#sky</a> <a href=\"https://pixelfed.social/discover/tags/jellyfish?src=hash\" title=\"#jellyfish\" class=\"u-url hashtag\" rel=\"external nofollow noopener\">#jellyfish</a> <a href=\"https://pixelfed.social/discover/tags/Alentejo?src=hash\" title=\"#Alentejo\" class=\"u-url hashtag\" rel=\"external nofollow noopener\">#Alentejo</a> <a href=\"https://pixelfed.social/discover/tags/deepspace?src=hash\" title=\"#deepspace\" class=\"u-url hashtag\" rel=\"external nofollow noopener\">#deepspace</a> <a href=\"https://pixelfed.social/discover/tags/alltogether?src=hash\" title=\"#alltogether\" class=\"u-url hashtag\" rel=\"external nofollow noopener\">#alltogether</a> <a href=\"https://pixelfed.social/discover/tags/jellyfish?src=hash\" title=\"#jellyfish\" class=\"u-url hashtag\" rel=\"external nofollow noopener\">#jellyfish</a> <a href=\"https://pixelfed.social/discover/tags/nebula?src=hash\" title=\"#nebula\" class=\"u-url hashtag\" rel=\"external nofollow noopener\">#nebula</a>",
