聲音化：水母星雲超新星殘骸
Sonified: The Jellyfish Nebula Supernova Remnant
發表日期：2024-03-25
超新星遺蹟聽起來像什麼？雖然聲音是物質的壓縮波，不能傳入虛空，但聲音的解釋可以幫助聽眾以一種新的方式欣賞和理解超新星遺蹟的視覺影像。最近，水母星雲（IC 443 ）被創造性地聲化了。 在這段聲音增強影片中，當一條假想線經過一顆恆星時，播放的是水滴落入水中的聲音，這種聲音與星雲的水生名字特別相關。 此外，當下降線穿過發出紅色光芒的氣體時，會發出低沉的聲音，綠色發出中間音調，而藍色則會發出音調相對較高的聲音。創造水母星雲的超新星發出的光大約在 3 . 5 萬年前離開，當時人類還處於石器時代。 在接下來的一百萬年裡，星雲將慢慢消散，不過爆炸也產生了一顆緻密的中子星，它將無限期地存在下去。
原文：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.
