  • It is almost the end of the winter,

    譯者: Lilian Chiu 審譯者: Adrienne Lin

  • and you've woken up to a cold house,

    冬天快要結束了,

  • which is weird, because you left the heater on all night.

    你在一間很冷的房子裡醒來,

  • You turn on the light.

    這很奇怪,因為你整晚都有開暖氣。

  • It's not working.

    你把燈打開。

  • Actually, the coffee maker, the TV -- none of them are working.

    它卻沒反應。

  • Life outside also seems to have stopped.

    其實,咖啡機、電視全都沒反應。

  • There are no schools,

    外面的生活似乎也停止下來了。

  • most of the businesses are shut,

    沒有學生上學,

  • and there are no working trains.

    大部份的商店都沒開,

  • This is not the opening scene of a zombie apocalypse movie.

    也沒有火車在跑。

  • This is what happened in March 1989 in the Canadian province of Quebec,

    這並不是殭屍世界末日電影的開場。

  • when the power grid lost power.

    這是 1989 年 3 月在 加拿大魁北克省發生的事,

  • The culprit?

    電力網失去了電力。

  • A solar storm.

    肇事者是誰?

  • Solar storms are giant clouds of particles

    太陽風暴。

  • escaping from the Sun from time to time,

    太陽風暴是種巨型雲,

  • and a constant reminder that we live in the neighborhood of an active star.

    由偶爾逃離太陽的粒子形成,

  • And I, as a solar physicist,

    它常常提醒我們, 我們住在活躍天體的附近。

  • I have a tremendous chance to study these solar storms.

    我是太陽物理學家,

  • But you see, "solar storm chaser"

    我有很棒的機會可以 研究這些太陽風暴。

  • is not just a cool title.

    但,「太陽風暴追逐者」

  • My research helps to understand where they come from,

    實在不是個酷頭銜。

  • how they behave

    我的研究是在協助 了解它們從何而來、

  • and, in the long run,

    它們的行為是什麼,

  • aims to mitigate their effects on human societies,

    以及長期目標

  • which I'll get to in a second.

    是要減輕它們對人類社會的影響,

  • At the beginning of the space exploration age 50 years ago only,

    我等下就會談到這點。

  • the probes we sent in space

    在太空探險時代剛開始時, 大約才五十年前,

  • revealed that the planets in our Solar System

    我們送上太空的探測器

  • constantly bathe in a stream of particles that are coming from the Sun

    發現在我們太陽系中的星球

  • and that we call the solar wind.

    經常會沉浸在來自 太陽的粒子流當中,

  • And in the same way that global wind patterns here on Earth

    這就是我們所稱的太陽風。

  • can be affected by hurricanes,

    就像在地球上,全球的風模式會

  • the solar wind is sometimes affected by solar storms

    受到颶風的影響一樣,

  • that I like to call "space hurricanes."

    太陽風有時也會被太陽風暴影響,

  • When they arrive at planets,

    我喜歡稱它為「太空颶風」。

  • they can perturb the space environment,

    當它們到達星球時,

  • which in turn creates the northern or southern lights,

    可能會擾亂太空環境,

  • for example, here on Earth,

    接著就會創造出北極光和南極光,

  • but also Saturn

    比如,在地球這裡,

  • and also Jupiter.

    在土星也有,

  • Luckily, here on Earth,

    還有木星。

  • we are protected by our planet's natural shield,

    幸運的是,在地球上,

  • a magnetic bubble that we call the magnetosphere

    我們受到我們星球的 天然屏罩所保護,

  • and that you can see here on the right side.

    也就是被稱為磁氣圈的磁場泡泡,

  • Nonetheless, solar storms can still be responsible

    可以在畫面的右手邊看到。

  • for disrupting satellite telecommunications and operations,

    但,太陽風暴仍然會造成

  • for disrupting navigation systems, such as GPS,

    衛星通信和運作的中斷、

  • as well as electric power transmission.

    如 GPS 的導航系統中斷,

  • All of these are technologies on which us humans rely more and more.

    以及影響電力輸送。

  • I mean, imagine if you woke up tomorrow without a working cell phone --

    上述這些科技都是人類 越來越仰賴的科技。

  • no internet on it,

    想像一下,如果你明天早上起床, 發現手機不能用了-

  • which means no social media.

    沒有網路連線,

  • I mean, to me that would be worse than the zombie apocalypse.

    也就是說,沒有社交媒體。

  • (Laughter)

    對我來說,那比殭屍世界末日還慘。

  • By constantly monitoring the Sun, though,

    (笑聲)

  • we now know where the solar storms come from.

    不過,透過持續監控太陽,

  • They come from regions of the Sun

    我們現在知道太陽風暴從何而來。

  • where a tremendous amount of energy is being stored.

    它們來自太陽上

  • You have an example here,

    儲存大量能量的區域。

  • as a complex structure hanging above the solar surface,

    這裡有個例子,

  • just on the verge of erupting.

    有個複雜的結構掛在太陽表面上,

  • Unfortunately, we cannot send probes

    正在爆發邊緣。

  • in the scorching hot atmosphere of the Sun,

    不幸的是,我們無法把探測器送到

  • where temperatures can rise up to around 10 million degrees Kelvin.

    太陽的這種灼熱大氣當中,

  • So what I do is I use computer simulations

    在這裡可以達到 絕對溫度 1000 萬度 K。

  • in order to analyze but also to predict the behavior of these storms

    所以,我的做法是用電腦模擬,

  • when they're just born at the Sun.

    來分析和預測這些風暴的行為,

  • This is only one part of the story, though.

    當它們剛在太陽上誕生就開始進行。

  • When these solar storms are moving in space,

    不過,這只是故事的一部份。

  • some of them will inevitably encounter space probes

    當這些太陽風暴在太空中移動時,

  • that we humans have sent in order to explore other worlds.

    當中有些難免會遇到太空探測器,

  • What I mean by other worlds is, for example, planets,

    我們人類送出去探索 其他世界的探測器。

  • such as Venus or Mercury,

    我所謂的其他世界, 指的是比如其他星球,

  • but also objects, such as comets.

    像是金星或水星,

  • And while these space probes have been made

    還有物體,像是慧星。

  • for different scientific endeavors,

    雖然這些太空探測器

  • they can also act like tiny cosmic meteorological stations

    是被設計來做不同的科學用途,

  • and monitor the evolution of these space storms.

    它們也可以被當作 小型的宇宙氣象站,

  • So I, with a group of researchers, gather and analyze this data

    用來監控這些太空風暴的演化。

  • coming from different locations of the Solar System.

    所以我和一群研究者一同分析

  • And by doing so, my research shows that, actually,

    這些來自太陽系不同地點的資料。

  • solar storms have a generic shape,

    這麼做之後,我的研究顯示,其實,

  • and that this shape evolves as solar storms move away from the Sun.

    太陽風暴有個一般的形狀,

  • And you know what?

    當太陽風暴遠離太陽之後, 形狀就會逐漸形成。

  • This is key for building tools to predict space weather.

    你們知道嗎?

  • I would like to leave you with this beautiful image.

    這就是打造太空天氣 預測工具的關鍵。

  • This is us here on Earth,

    我把這張美麗的影像留給各位。

  • this pale blue dot.

    這就是我們的地球,

  • And while I study the Sun and its storms every day,

    這個淡藍色的圓點。

  • I will always have a deep love for this beautiful planet --

    雖然我每天都在研究太陽和太陽風暴,

  • a pale blue dot indeed,

    但我一直都深愛著這個美麗的星球,

  • but a pale blue dot with an invisible magnetic shield

    的確,這是個淡藍色的圓點,

  • that helps to protect us.

    但這個淡藍色的圓點 有個隱形的磁場屏罩,

  • Thank you.

    能協助保護我們。

  • (Applause)

    謝謝。

It is almost the end of the winter,
