Our galactic home, the Milky Way, is big. Most galaxies are far smaller. And it’s not easy being one of those little galaxies—a big galaxy’s gravity can rob their gas. And gas creates new stars, so losing gas spells the end of star-making. That's what happened to nearly all the small galaxies orbiting the Milky Way.
我們銀河上的家，銀河，是很大的。大部分銀河系星系都是超小的呢。而且要成為那些小星系中的一員還挺不容易——一個大星系的重力能夠搶奪它們的氣體層。而氣體能夠創造恒星，所以氣體流失就意味著無法製造恒星了。這就是所有圍繞著銀河系的那些小星系上面正在上演的悲劇。
But a small galaxy can still succeed. Take the example of Leo P. Discovered in 2013, the galaxy Leo P lies some 5.3 million light-years from Earth. And it contains only about a hundred-thousandths as many stars as the Milky Way. But it’s thriving nevertheless.
但是小星系還是有機會逃脫的。比如2013年發現的這顆Leo P 這顆星系Leo P 坐落在距離地球五百三十萬光年的距離。並且它只含有銀河系所含恒星數量的千分之一百。但它現在依然欣欣向榮的存在著。
So what’s Leo P's secret for success? Pretty simple: steer clear of gas-grabbing big galaxies. Leo P still has lots of gas. In fact, Leo P's gas outweighs its stars. Astronomers used the Hubble Space Telescope to study the small galaxy and published their findings recently in The Astrophysical Journal.
那麼它能倖存的奧秘呢?十分簡單：牢牢抱緊吸氣的大星系的大腿。Leo P 現在還有不少氣體。實際上，Leo P 的氣體比它所含恒星還多。天文學家們利用哈勃天文望遠鏡研究了這些小星系並且已經將他們的研究發現發表在《天文物理雜誌上》。
All that gas means that Leo P can keep making new stars. So the diminutive galaxy has a bright future, as long as it keeps obeying the number one rule of survival: don’t let any behemoths siphon off your gas.
有這些氣體就意味著Leo P 能不斷創造新恒星。所以這個小型星系無疑有光明的未來，只要它保持遵守生存法則第一條：堅決抵抗虹吸氣體的侵略行為。
