We've got a big update, a huge update on our favorite interstellar object.

我們有一個大更新，關於我們最喜歡的星際天體有個巨大的更新。

It could be the biggest update in the solar system.

這可能是太陽系裡最大的更新了。

You know how the last time we talked about it went behind the sun, then it got brighter, then it got bluer, then it started to go faster.

你知道上次我們講到它經過太陽後面，然後它變亮，變藍，然後開始加速。

Well, guess what, we just got new images of it.

好了，猜猜怎麼著，我們剛拿到它的新影像。

And to add some more strangeness to the 3i Atlas saga, because like I don't want to over hype this, but

為了讓 3i Atlas 的故事更添奇幻色彩，因為我不想過度炒作，但是

It does not have a very big, very noticeable cometary tail.

它沒有一個很大、很明顯的彗星尾。

That's what we were thinking we were going to see.

這就是我們原本預期會看到的。

So let's get straight over to Harvard astronomer Professor Avi Loeb, the world renowned expert on all these things, all things interstellar.

那麼，我們就直接連線到哈佛大學天文學家 Avi Loeb 教授，他是這所有星際事務的全球知名專家。

Professor, the last time we spoke, which was like the day before yesterday, you were saying that when it went behind the sun, the natural explanation for the non gravitational acceleration and the thrust might be because it burned off a bunch of chemicals or something.

教授，上次我們通話，大概是前天吧，您說當它經過太陽後面時，對於非重力加速度和推力的自然解釋，可能是因為它燃燒掉了一堆化學物質之類的。

And that was giving it the thrust to the tune of like 13%.

And we would see a humongous tail, maybe.

而且我們可能會看到一個巨大的彗星尾。

Yeah, that's very surprising because there should have been a very massive cloud of gas and dust around it based on what we know about comets.

是的，這非常令人驚訝，因為根據我們對彗星的瞭解，它周圍應該有一大團氣體和塵埃。

In fact, we see other comets in the solar system that have a beautiful tail away from the sun behind them.

事實上，我們在太陽系裡看到的其他彗星，都有一個美麗的彗星尾朝遠離太陽的方向。

But in our case of three Eye Atlas, it looks like a fuzzy ball of light.

但在我們的 3i Atlas 的情況下，它看起來就像一個模糊的光球。

Even after it passed through perihelion, it was heated by 770 watts per square meter.

即使它通過了近日點，它仍然被每平方米 770 瓦特的能量加熱。

And we know that the previous plume of gas was mostly carbon dioxide.

我們知道先前噴發的氣體主要是二氧化碳。

And carbon dioxide ices can sublimate at a much lower temperature than water ice.

而二氧化碳冰比水冰在低得多的溫度下就能昇華。

So we should have seen it break up or at the very least disintegrate to a very dense and massive cloud of gas and dust that is pushed away from the sun by the solar radiation and the solar wind.

所以我們應該看到它解體，或者至少崩解成一大團濃密且巨大的氣體和塵埃，被太陽輻射和太陽風推離太陽。

那麼問題來了，到底怎麼回事？

One possibility is that what evaporates from it are fragments of ice and they get vaporized by sunlight before they have a chance to turn around and show up as a plume of glow behind it away from the sun.

一種可能性是，從它蒸發出來的是冰的碎片，它們在有機會轉向並在遠離太陽的方向形成一團發光噴霧之前，就被陽光蒸發了。

That's one possible interpretation, but otherwise I just don't know what to make of it.

這是一種可能的解釋，但除此之外，我真的不知道該如何解釋。

There was also a blue color that was noticed just a few days ago.

And also in addition to that, it became brighter by a factor of five.

另外，它的亮度也增加了五倍。

So what I'M saying is, you know, there are things we don't fully understand about this object.

所以我的意思是，你知道，有些事情我們還沒完全搞懂這個天體。

And I think all of us will wait for the data that will come in the coming weeks, and

我想我們大家都會等著接下來幾週會進來的數據，

especially on December 19th, when it comes closest to Earth.

尤其是在 12 月 19 日，那時候它離地球最近。

And let's hope we don't get unwanted gifts for our holidays.

希望我們不會在假期收到不想要的禮物。

Or at least maybe those gifts will be nice and friendly and wonderful and help us figure the universe out.

或者至少，也許那些禮物會是好的、友善的、很棒的，能幫助我們理解宇宙。

I know that we've been asking you about this and we were all expecting to see a tale, and

我知道我們一直在問你這個問題，我們都期待看到一條尾巴，而且

we asked you for a natural, plausible explanation.

我們請你給我們一個自然、合理的解釋。

I think, you know, it's like a blind date with an interstellar object that came from an environment that is alien to us.

我想，你知道，這就像是跟一個來自對我們來說很陌生的環境的星際天體來場盲目約會。

And I think the key question is whether it's natural or technological.

而我認為關鍵問題是，它是自然的還是科技的。

The secondary question, if it's natural, what kind of an environment did it come from?

次要問題是，如果它是自然的，它來自什麼樣的環境？

It must be a common environment that produces large packages delivered to our mailbox, and

它一定是一個常見的環境，會產生送到我們信箱的大包裹，而且

And it's really the reason why science is worthwhile doing because we can gain new knowledge.

這也正是科學之所以值得做的原因，因為我們可以獲得新知識。

And that goes against the tendency of experts to pretend to be the adults in the room that know the answer in advance.

這與專家們總想扮演房間裡那個預知答案的成年人的傾向背道而馳。

Well, unlike 3i Atlas, this tale is far from over and we will be dialing you up every twist and turn.

嗯，不像 3i Atlas，這個故事還遠未結束，我們會一路追蹤每一個轉折。

Avi Loeb, always a pleasure to see you and to talk to you and we can't wait to see what happens next.

Avi Loeb，很高興見到您並與您交談，我們迫不及待想知道接下來會發生什麼。
