超新星遗迹听起来像什么？虽然声音是物质中的压缩波，不会进入空的空间，但解释性声音可以帮助听众以一种新的方式欣赏和理解超新星遗迹的视觉图像。最近，海蜇星云（IC 443）被很有创意地发出了声音。在这段声音增强的视频中，当一条想象的线经过一颗恒星时，就会播放水滴落水的声音，这种声音与星云的水生同名特别相关。此外，当下降线穿过发出红光的气体时，会发出低音调，而绿色发出中音，蓝色发出相对较高的音调。形成水母星云的超新星发出的光大约在35000年前离开地球，那时人类还处于石器时代。星云将在接下来的一百万年里慢慢消散，尽管爆炸也产生了一颗致密的中子星，它将无限期地存在下去。

What does a supernova remnant sound like? Although sound is a compression wave in matter and does not carry into empty space, interpretive sound can help listeners appreciate and understand a visual image of a supernova remnant in a new way. Recently, the Jellyfish Nebula (IC 443) has been sonified quite creatively. In the featured sound-enhanced video, when an imaginary line passes over a star, the sound of a drop falling into water is played, a sound particularly relevant to the nebula's aquatic namesake. Additionally, when the descending line crosses gas that glows red, a low tone is played, while green sounds a middle tone, and blue produces a tone with a relatively high pitch. Light from the supernova that created the Jellyfish Nebula left approximately 35,000 years ago, when humanity was in the stone age. The nebula will slowly disperse over the next million years, although the explosion also created a dense neutron star which will remain indefinitely.
