小美人魚能不能變成星塵呢？在這個壯麗的星雲中，看起來是有可能的哦！這幅圖片展示了美人魚星雲（Mermaid Nebula），它也叫做斗魚星雲（Betta Fish Nebula），是G296.5+10.0超新星殘骸的一部分。圖片中的藍色來自雙重電離的氧氣（OIII），而深紅色則是氫氣發出的光。這個星雲距離我們幾千光年，年齡大約有一萬年，是因為一顆巨大的星星爆炸成為超新星所形成的。它留下了一顆奇特的脈衝星，這是一顆年輕、靜默的中子星，每秒轉動約兩次。圖片中的亮星與這個星雲無關。脈衝星可以在X射線中被檢測到，但至今在可見光中還沒有找到它，因此在這幅圖片中我們看不到這顆脈衝星。

Could the Little Mermaid turn into stardust instead of seafoam? It would seem so in this beautiful nebula. The featured image shows the Mermaid Nebula, also known as the Betta Fish Nebula, which is part of the G296.5+10.0 Supernova Remnant. The blue color visible here originates from doubly ionized oxygen (OIII), while the deep red is emitted by hydrogen gas. Estimated to be located a few thousand light-years away and about 10,000 years old, this nebula was formed when a massive star exploded as a supernova. It left behind a peculiar pulsar, a young radio-quiet neutron star that spins around about twice every second. The bright stars shown in the image are unassociated with the nebula. The pulsar can be detected in the X-rays but it does not have a confirmed detection in the optical (visible light) so far. As a result, the pulsar itself is not visible in this image.
