But if you trace the paths of the meteors backwards, you'll see they all seem to come from single point, called the radiant point. - 但我们认为你应该回想知道今晚流星雨的辐射点，因此你可以在这样一个没有月光的夜晚，想象下流星像从天空中的这一点倾倒下来一样。
But we thought you'd enjoy knowing where the radiant is tonight, so you can imagine the meteors pouring from this point in the sky, in a sky totally free of moonlit glare! - 狮子座流星群的得名是由于它们流星辐射点位于狮子座。 根据你所处的地理位置，狮子座一般会在凌晨1点到3点左右出现在地平线上的东北方向。
The Leonids are so named because they seem to radiate from the constellation Leo, the lion, which rises above the northeastern horizon between 1 a.m. and 3 a.m., depending on your location.
