NASAさんのインスタグラム写真 - (NASAInstagram)「Hubble, Hubble, Hubble can’t you see? Sometimes your photos just hypnotize me. 🌀⁣⁣⠀⁣ ⁣⁣⁣ ⁣ Outright mesmerizing, this spiral galaxy (NGC 5468) was captured in beautiful detail by our @NASAHubble Telescope. See those REALLY bright lights? Those are dying stars. ⁣ ⁣ ⁣ Such events create catastrophic explosions known as supernovae, which are some of the most dramatic occurrences in the universe. By either depleting their fuel and collapsing inward or siphoning mass off a companion object and igniting runaway nuclear fusion, they result in intensely bright objects that can rival the light of a whole galaxy. Can you spot the supernovae in this spiral galaxy? ⁣⁣⠀⁣ ⁣⁣⠀⁣ Image credit: @europeanspaceagency/Hubble & NASA, W. Li et al⁣⁣⠀⁣ ⁣⁣⠀⁣ #NASA #Dramatic #Galaxy #Biggie #Stars #ShineBright⁣⁣⠀⁣」12月7日 6時29分
