科学家在太空意想不到的区域发现“合唱波”
📖 逐句对照翻译
International researchers recently released a study on bursts of energy in an unexpected area of space.
国际研究人员最近发布了一项关于太空意外区域能量爆发的研究。
Scientists call the energetic activity “chorus waves” because they are said to move at the same frequency as sounds humans can hear.
科学家将这种高能活动称为“合唱波”，因为据说它们的频率与人类能听到的声音频率相同。
When the energy is turned into audio signals, the waves sound like birds chirping.
当能量转化为音频信号时，这些波听起来就像鸟儿在鸣叫。
Researchers have known about chorus waves in space for many years.
研究人员多年来一直知道太空中的合唱波。
But the latest research has found the waves exist 100,000 kilometers from Earth.
但最新研究发现，这些波存在于距离地球10万公里处。
Chorus waves have never before been measured at such a big distance from a planet.
合唱波从未在距离行星如此遥远的地方被测量到。
In an email, study writer Chengming Liu from Beihang University in Beijing wrote: “They are one of the strongest and most significant waves in space.”
在一封电子邮件中，来自北京航空航天大学的研究作者刘成明写道：“它们是太空中最强大、最重要的波之一。”
Allison Jaynes is a space physicist at the University of Iowa who was not involved with the study.
艾莉森·杰恩斯是爱荷华大学的一位太空物理学家，并未参与这项研究。
Speaking about the recent study, Jaynes said, “That opens up a lot of new questions about the physics that could be possible in this area.”
谈到最近的研究，杰恩斯说：“这为该领域可能存在的物理学开辟了许多新问题。”
The newfound chorus waves were detected in an area where Earth's magnetic field is stretched out.
新发现的合唱波是在地球磁场被拉伸的区域探测到的。
Scientists said they did not expect to find the waves there.
科学家们表示，他们没想到会在那里发现这些波。
The discovery raises new questions about how the chirping waves form.
这一发现提出了关于啁啾波如何形成的新问题。
Jaynes added, “We definitely need to find more of these events.”
杰恩斯补充道：“我们确实需要找到更多这类事件。”
Scientists still are not sure how the waves develop.
科学家们仍不确定这些波是如何形成的。
But they think Earth’s magnetic field may have something to do with it.
但他们认为地球磁场可能与此有关。
For many years, radio antennas have picked up chorus waves.
多年来，无线电天线一直能接收到合唱波。
This includes receivers at an Antarctica research station in the 1960s.
这包括20世纪60年代南极研究站的接收器。
And NASA’s two Van Allen Probes heard the chirping sounds from Earth's radiation belts at a closer distance than the newest observations.
而NASA的两颗范艾伦探测器在比最新观测更近的距离上，听到了来自地球辐射带的啁啾声。
The latest chorus waves were picked up by NASA's Magnetospheric Multiscale satellites.
美国宇航局的磁层多尺度卫星捕捉到了最新的合声波。
They were launched in 2015 to explore the Earth and the sun's magnetic fields.
它们于2015年发射，用于探索地球和太阳的磁场。
Chorus waves have also been found near other planets including Jupiter and Saturn.
在木星和土星等其他行星附近也发现了合唱波。
The waves can produce high-energy electrons.
波浪能产生高能电子。
That means they can threaten satellite communications.
这意味着它们可以威胁卫星通信。
The researchers said their findings suggest that chorus waves might be found everywhere in the magnetic fields of planets.
研究人员表示，他们的发现表明，合唱波可能普遍存在于行星的磁场中。
The study was released on January 22 in the scientific publication Nature.
这项研究于1月22日发表在科学出版物《自然》上。
