For a dozen Magellanic penguins in Argentina, it was a big day.

对阿根廷的12只麦哲伦企鹅来说，这是重要的一天。

The two biggest are the Large and Small Magellanic Clouds, visible from the southern hemisphere.

最大的两个是大麦哲伦云和小麦哲伦云，从南半球可以看到它们。

From the Large Magellanic Cloud or LMC, their origin is explained by the decay of binary systems.

从大麦哲伦星云（LMC）来看，它们的起源可以用双星系统的衰变来解释。

Researchers spent nearly thirty years tracking chicks at Punta Tombo, the world's largest colony of Magellanic penguins.

研究人员们花了将近30年的时间追踪Punta Tombo群岛上生活的这群小家伙，这里是世界上最大的麦哲伦企鹅栖息地。

So climate change will likely pose a challenge not only in Magellanic penguins, but other seabirds as well.

由此可见，气候变化将不仅对麦哲伦企鹅带来威胁，而且对其它种类的海鸟也是有巨大伤害的。

This is the Large Magellanic Cloud.

这是大麦哲伦星云。

Oscar was able to do this because he had the Large Magellanic Cloud essentially memorized.

奥斯卡之所以能够做到这一点，是因为他基本上记住了大麦哲伦星云。

Star-forming regions, one is in the Milky way, our galaxy and two nearby galaxies, the Magellanic clouds.

恒星形成区，一个是在银河系，我们的银河系和附近的两个星系，麦哲伦星云。

The Large Magellanic Cloud is right in the middle of that image, but despite its name, it's really small.

大麦哲伦云就在该图像的中间，但尽管它的名字如此， 但它确实很小。

This point of light that he saw appearing in the Large Magellanic Cloud turned out to be a supernova.

他看到的这个出现在大麦哲伦星云中的光点，竟然是一颗超新星。

Both are irregular in shape, though the Large Magellanic Cloud is barely coherent enough to qualify as a disrupted, though small, barred spiral.

这两者的形状都是不规则的，尽管大麦哲伦星云几乎没有足够的连贯性，以称得上是一个中断的，但小的棒旋星系。

These two dwarf galaxies are the Magellanic clouds which, together with at least 80 others, make up what's known as the local group of galaxies.

这两个矮星系是麦哲伦星云，它与至少 80 个其他星系一起，构成了所谓的本星系群。

The last supernova that sent detectable neutrinos to Earth was in 1987 on the edge of the Tarantula Nebula in the large Magellanic Cloud, a nearby galaxy.

最后一次向地球发送可探测中微子的超新星发生在 1987 年，位于附近星系大麦哲伦星云中的狼蛛星云边缘。

And if the computer simulation is correct, not only many hypervelocity stars, but also neutron stars as well as black holes are rushing towards our galaxy from the Large Magellanic Cloud.

如果计算机模拟是正确的，不仅有许多超高速恒星，还有中子星和黑洞从大麦哲伦星云冲向我们的星系。

If you look up at the southern sky, you can actually see two of these small galaxies, the largest of the small galaxies that are orbiting our Milky Way, the Large Magellanic Cloud and the Small Magellanic Cloud.

如果你抬头仰望南方的天空，你实际上可以看到两个这样的小星系，即大麦哲伦星云和小麦哲伦星云，它们是围绕我们银河系运行的最大的小星系。
