The Andromeda galaxy is about 2.5 million light years away.

仙女座星系距离我们大约250万光年。

The Andromeda galaxy, for example, is about 2.5 million light years away.

例如，仙女座星系距离我们大约250万光年。

Our Milky Way is part of the Local Group, and will one day collide with the Andromeda galaxy.

我们的银河系是本星系的一部分，有一天会与仙女座星系相撞。

The Andromeda galaxy which is even bigger than our own galaxy is currently on a four billion year-long collision course with us.

仙女座星系比我们的星系还要大，它目前正朝着与我们相碰撞的轨道行进，过程长达 40 亿年。

And another 2 million years until we set foot in the nearest neighbor, the Andromeda galaxy.

再过200万年，直到我们踏上最近的邻居仙女座星系。

That's a simulation of the Milky Way galaxy and the Andromeda galaxy colliding together, and all these wisps of smoke getting thrown out are stars.

这就是银河系与仙女座相撞时的模拟画面，这些烟一样的东西其实都是恒星。

It's the Andromeda galaxy, which is roughly the same size as our own, an island of hundreds of billions of stars, 25 million million million kilometres in that direction.

仙女座星系，它和银河系大小相仿，一共有几千亿颗恒星，它就在那个方向，离我们有 2500 亿亿千米。

It's going to take four billions years, when our galaxy will collide with the Andromeda galaxy, with a 12% chance that our entire solar system would be ejected from the newly-formed galaxy out to wherever.

我们银河系将与仙女座星系碰撞，将会在未来四十亿年内发生，而且我们太阳系有12%的几率会被新产生的星系弹射到不知道哪里去。
