[漢羅] 船帆座超新星殘骸 ê 雲絲

爆炸已經煞矣，毋過後壁猶閣有。 差不多 1 萬 1 千年前，船帆座 內底有一粒星 爆炸，產生一个 tī 短短時間內，光甲人類目睭看會著 ê 光點，這 tī 早期 歷史內底有紀錄著。 恆星 ê 外層氣體挵著 星際媒介物，引起 震波，到今猶看會著。 這張影像 有翕著 可見光 波段 ê 一部份雲絲 kah 大型震波。 氣體 ùi 爆炸 ê 恆星飛出來了後，會 衰變、kah 星際媒介物發生反應、產生無仝色、無仝能量 ê 光。 Tī 船帆座超新星殘骸 中心 留落來 ê 是一粒 脈動星，是一粒 kah 核物質 仝款實密 ê 星，伊 ê 自旋 速度是 1 秒鐘超過 10 改。

[English] Filaments of the Vela Supernova Remnant

The explosion is over, but the consequences continue. About eleven thousand years ago, a star in the constellation of Vela could be seen to explode, creating a strange point of light briefly visible to humans living near the beginning of recorded history. The outer layers of the star crashed into the interstellar medium, driving a shock wave that is still visible today. The featured image captures some of that filamentary and gigantic shock in visible light. As gas flies away from the detonated star, it decays and reacts with the interstellar medium, producing light in many different colors and energy bands. Remaining at the center of the Vela Supernova Remnant is a pulsar, a star as dense as nuclear matter that spins around more than ten times in a single second.
