  • Have you ever wondered how big the entire universe is?

    你曾經想過宇宙到底有多大嗎?

  • The visible universe is unimaginably huge but there

    宇宙是難以想像的大

  • is one image that can give us a small glimpse at its

    但這裡有一張影像能讓我們看到

  • awe-inspiring scale, and that is the

    這令人驚豔的範圍中的一小角

  • Hubble Deep Field Image.

    而這就是哈伯深空影像

  • [Fanfare jingle]

  • [Explosion sound and electric guitar riff]

  • In 1995, astronomers wanted to see what would happen

    1995年,天文學家們想知道

  • if they pointed the new Hubble Space Telescope at an

    如果他們放置一架新的哈伯太空望遠鏡

  • area of the sky that was nearly devoid of all stars.

    到虛無的深空中,會拍到甚麼東西

  • They let it soak up light for over 140 hours over a

    他們讓望遠鏡接收超過140小時的光線

  • span of 10 days and what they saw was nothing short of spectacular.

    經過時10天的時間,他們得到的結果只能用壯觀來形容

  • This, is the Hubble Deep Field Image. [Orchestral music building]

    而這個,就是所謂的哈伯深空影像

  • What you're seeing here is not just a few stars,

    你現在看到的不僅僅是幾顆恆星

  • nebulas and star clusters but each and every dot

    星雲,還是星團。而是你看到影像上的每一個點

  • and fuzzy patch you are seeing is an entire galaxy,

    每一個模糊的碎屑,都是一整個銀河系

  • each containing around 100 billion stars!

    每一個都包含了1000億顆恆星!

  • To get an idea of how many stars are in each one of

    為了瞭解每一個銀河系裡有多少顆恆星

  • those galaxies, imagine an Olympic-sized swimming

    想像一下一座符合奧運標準的游泳池

  • pool and fill it with standard 1.5cm marbles.

    倒入直徑1.5公分的彈珠填滿它

  • If my calculations are correct (taking into account

    假如我的計算沒錯

  • the max density of close-packed spheres),

    (考慮到球體能堆積的最大密度)

  • it would fit about 1 billion marbles.

    游泳池能填入10億顆彈珠

  • That would mean we'd need 100 Olympic swimming

    這意味著我們需要100座奧運游泳池的彈珠量

  • pools full of marbles to equal the number of stars in an average galaxy!

    才相等於一個銀河系裡平均恆星的數量!

  • In a similar, more recent capture called the Hubble

    同樣地,最近抓到所謂的

  • ULTRA Deep Field image, we can see around 10,000

    哈伯超深空影像,我們可以看到大約一萬個銀河系

  • galaxies, each with around 100 billion stars.

    每一個銀河系包含了1000億顆恆星

  • Pretty cool right? But you haven't heard the most amazing thing yet!

    非常酷對吧?但還有更令人驚豔的事在後頭呢!

  • This image is not the entire night sky - far from it!

    這影像還不是整個夜空 - 還差得很遠!

  • This is only a tiny fraction of the sky -

    這只是一小部分天空 -

  • one 13 millionth to be exact!

    事實上只是1300萬分之一而已!

  • Look at the size of the D on the front of an

    看看這個一分美元硬幣正面上D的大小

  • American penny then hold the penny up to the sky at arm's length.

    拿著這硬幣伸長手臂指向天空

  • The area of sky that the Ultra Deep Field image takes up

    超深空影像拍到的宇宙的範圍

  • is roughly contained entirely in that tiny "D".

    大概就是涵蓋於這小小的「D」裡面

  • The Hubble Deep Field Images allow us to peer deeper

    哈伯超深空影像讓我們看見更深遠的宇宙

  • into space AND time than we have ever seen before.

    以及我們以往未曾見過的時間

  • I say deeper into time because some of these objects

    我會說時間是因為有些星體離我們太遠了

  • are so far away, the light coming from them has taken

    光線從那地方傳過來

  • up to 13 billion years to get to us so we're seeing

    需要130億年

  • them as they looked less than a billion years after

    所以我們只能看到大爆炸後距離我們10億光年的距離

  • the Big Bang, long before the Earth was even formed.

    甚至那時地球都還沒形成

  • Some of these distant objects are called quasars

    有些距離我們很遠的天體是所謂的類星體

  • which are the most powerful and luminous objects in the universe.

    這是宇宙中最強大也是最亮的星體

  • Even though they're only about the size of our solar

    雖然他們的大小只如同我們太陽系一般

  • system, they emit up to 1000 times more energy than

    他們可以發射超過我們的整個銀河系

  • the ENTIRE Milky Way galaxy, which contains between 200 and 400 billion stars.

    2000億到4000億顆恆星1000倍的能量

  • They're made up of supermassive black holes that are

    他們是由超大黑洞所組成的

  • consuming so much material, that they shoot giant

    因為吸收超多物質,所以它們幾乎可以以光速

  • jets of particles traveling at nearly the speed of light,

    發射出巨大的粒子束

  • thousands of light years into space!

    並且距離達到數光年這麼遠!

  • Yeah, quasars are pretty awesome.

    是的,類星體非常令人驚艷

  • Looking at this image is a humbling experience,

    觀看這影像著實是個震撼人心的經驗

  • but to me, it just shows how amazing our universe is

    但對我來說,它只是說明了我們的宇宙是多麼令人驚訝的

  • and how much there is left for us to explore.

    而且還有許多地方等著我們去探索

  • It's almost unfathomable that we could be the only life

    一切都還很難說是否我們只是這浩瀚宇宙中

  • in this vast universe.

    唯一的生命體

  • Peer into this image long enough and you'll start

    觀察這影像更久一點,你會開始想像

  • to imagine what awe-inspiring wonders could be

    在這遙遠且涵蓋數十億顆星球的銀河中

  • hiding in those distant galaxies full of billions

    還有甚麼令人讚嘆的奇觀

  • of planets. Scientists are learning more about our

    科學家每天都在研究

  • universe and our local galaxy every day.

    我們的宇宙跟我們的銀河系

  • Just imagine what they might find next!

    光是想像他們下次會發現甚麼就讓人振奮!
