科学家们录下了太阳的声音

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”.

你曾经想过太阳的声音是怎么样的吗？欧洲航天局和美国国家航空航天局的科学家们研究了20年的数据，试图倾听太阳的声音。他们说太阳发出的是一种深沉的、类似“心跳”的声音。

The scientists used a special observatory1 to measure vibrations2 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 solar3 flares4， chemical reactions and other things that happen inside the sun.

科学家使用一种特殊的天文台测量来自太阳的振动，然后他们把这些振动转换成不同的声音。科学家借此来探究太阳内部发生了什么。他们将更加深入了解太阳耀斑、化学反应和其他发生在太阳内部的情况。

The scientists explained how they created the sounds. Researchers turned data from space agencies into a “song”. Dr. Alex Young said， “We dont have straightforward5 ways to look inside the sun. We dont have a microscope6 to zoom inside the sun， so using the suns vibrations allows us to see inside of it.”

科学家解释了他们是如何制作声音的。研究人员把宇航局的数据转换成了一首“歌”。亚历克斯·杨博士说：“我们没有直接的方法观察太阳的内部。我们没有显微镜放大太阳的内部，因此我们通过太阳的振动来观察它的内部。”

“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 complexity7. That simple sound is giving us a probe8 inside a star. I think thats a pretty cool thing.”

“能量波在太阳内部传播、反彈。如果你的眼睛足够敏锐，实际上，眼睛能看到它。”他补充说：“最终，我们将了解太阳的层次和复杂性。那种声音就能让我们探测恒星内部。我觉得，那是一件极好的事情。”
