程度副詞

going on nearly 1,500 light-years from home.

as though something was passing in front of it.

彷彿有什麼東西從它面前經過。

Since then, scientists have been trying to figure out

從那時起，科學家們就一直在試圖找出

Then, in 2019, astronomers proposed a new,

然後，在2019年，天文學家提出了一個新的。

that might finally solve the mystery of Tabby's Star.

First, the star keeps brightening and dimming

第一，星辰不斷地亮起，又不斷地暗淡下去

While very young stars occasionally do this,

雖然很年輕的明星偶爾也會這樣做。

astronomers have never seen this behavior

但隨著時間的推移，肯定會越來越暗。

an advanced alien civilization is to blame.

一個先進的外星文明是罪魁禍首。

如果外星人建造了一個巨型基礎設施

called a Dyson Sphere to siphon off the star's energy,

稱為戴森球體，以吸取恆星的能量。

For one, you'd expect an orbiting megastructure

首先，你會期待一個軌道上的巨型基礎設施

to make regular, predictable trips around the star,

繞著恆星進行定期、可預測的旅行。

just like the  International Space Station

但是，到目前為止，還沒有明確的證據表明。

that the dips occur on a consistent schedule.

Brian Metzger: It's a little hard to test it.

布萊恩-梅茲格這有點難以測試。

Polan: That's Brian Metzger, an astrophysicist

那是布萊恩-梅茲格，一位天體物理學家。

Metzger: Things that go bump in the night.

Polan: Or strange phenomena in the universe,

波瀾：或者宇宙中的奇怪現象。

including the odd behavior of Tabby's Star.

Metzger says another theory has problems as well.

梅茨格說，另一種理論也有問題。

You see, some experts suggest a massive swarm

你看，一些專家建議，大規模的群居動物

This has the advantage that, unlike aliens,

這樣做的好處是，與外星人不同。

Like, why don't other stars show this behavior?

就像，為什麼其他明星沒有這種行為？

Polan: Basically, there would need to be something special

波瀾：基本上，需要有一些特別的東西。

about Tabby's Star to attract so many comets

to congregate at the same time at the same place.

Tabby's Star is just like any other star of its type.

Luckily, Metzger and his team may have a new solution.

幸運的是，梅茨格和他的團隊可能有一個新的解決方案。

in the Monthly Notices of the Royal Astronomical Society

數百萬年前圍繞這顆恆星運行。

而且，像木星和其他氣體巨行星一樣。

隨著時間的推移，它慢慢牽引著地球

out of its orbit and  towards Tabby's Star

But the planet's moons may have escaped this fate,

但這顆星球的衛星可能已經逃脫了這種命運。

instead getting trapped into orbit by Tabby's gravity.

而是被塔比的引力困在了軌道上。

could have melted off chunks of these icy moons,

可能已經融化了這些冰冷的衛星的塊狀物。

resulting in a colossal cloud of moon dust around the star.

導致恆星周圍出現巨大的月塵雲。

Now, this plan makes sense for a number of reasons.

現在，這個計劃是有意義的，原因有很多。

Metzger: Dust or small particulate grains

that's constantly morphing and changing its shape,
