爆炸结束了，但后果还在继续。大约一万一千年前，船帆座的一颗恒星发生了爆炸，产生了一个奇怪的光点，生活在有记载的历史初期的人类可以短暂地看到它。这颗恒星的外层撞上了星际介质，产生了至今仍可见的冲击波。这张特色图片在可见光下捕捉到了一些丝状和巨大的震动。当气体飞离爆炸的恒星时，它会衰变并与星际介质发生反应，产生许多不同颜色和能量带的光。船帆座超新星遗迹的中心是一颗脉冲星，一颗密度和核物质一样的恒星，在一秒钟内旋转十次以上。周一的日食图像：值得注意的提交给APOD

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.
