維拉超新星殘留物的燈絲
Filaments of the Vela Supernova Remnant

發表日期:2024-04-16
爆炸已經結束,但後果仍在繼續。 大約 1 . 1 萬年前,人們可以看到威拉星座的一顆恆星發生了爆炸,產生了一個奇怪的光點,生活在有文字記載的歷史初期附近的人類可以短暫地看到這個光點。 這顆恆星的外層撞入星際介質,產生的衝擊波至今仍清晰可見。 這張特寫圖片捕捉到了可見光下的一些絲狀巨大沖擊波。當氣體飛離被引爆的恆星時,會發生衰變並與星際介質發生反應,產生多種不同顏色和能量帶的光。留在維拉超新星殘留物中心的是一顆脈衝星,這是一顆像核物質一樣緻密的恆星,在一秒鐘內會旋轉十多圈。 週一的日食影像:提交給 APOD 的著名作品
原文: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.
