Have you ever thought about what the sun sounds like? Scientists from the European Space Agency and NASA studied 20 years of data to try to listen to the sun. They say the sun produces a sound like a low, deep “heartbeat”.
The scientists used a special observatory to measure vibrations from the sun. They then changed these vibrations into different sounds. The scientists will use these to find out what is happening inside the sun. They will understand more about solar flares, chemical reactions and other things that happen inside the sun.
The scientists explained how they created the sounds. Researchers turned data from space agencies into a “song”. Dr. Alex Young said, “We don’t have straightforward ways to look inside the sun. We don’t have a microscope to zoom inside the sun, so using the sun’s vibrations allows us to see inside of it.”
“Waves are travelling and bouncing around inside the sun, and if your eyes were sensitive enough, they could actually see this.” He added, “We are finally starting to understand the layers of the sun and the complexity. That simple sound is giving us a probe inside a star. I think that’s a pretty cool thing.”
你曾經想過太陽的聲音是怎么樣的嗎?歐洲航天局和美國國家航空航天局的科學家們研究了20年的數據,試圖傾聽太陽的聲音。他們說太陽發出的是一種深沉的、類似“心跳”的聲音。
科學家使用一種特殊的天文臺測量來自太陽的振動,然后他們把這些振動轉換成不同的聲音??茖W家借此來探究太陽內部發生了什么。他們將更加深入了解太陽耀斑、化學反應和其他發生在太陽內部的情況。
科學家解釋了他們是如何制作聲音的。研究人員把宇航局的數據轉換成了一首“歌”。亞歷克斯·楊博士說:“我們沒有直接的方法觀察太陽的內部。我們沒有顯微鏡放大太陽的內部,因此我們通過太陽的振動來觀察它的內部?!?/p>
“能量波在太陽內部傳播、反彈。如果你的眼睛足夠敏銳,實際上,眼睛能看到它?!彼a充說:“最終,我們將了解太陽的層次和復雜性。那種聲音就能讓我們探測恒星內部。我覺得,那是一件極好的事情?!?/p>
