Time for the Shoutout.
大喊时间到了。
What occurs when the sun crosses the equator, making day and night equal length the world over?
当太阳穿过赤道时会出现什么，使得全世界白天和黑夜一样长？
If you think you know it, shout it out.
如果你知道，就大声喊出来。
Is it an: (a) Eclipse, (b) Solstice, (c) Spectra, or (d), Equinox?
是：(a) 日食 (b)至日 (c)光谱 (d)秋分？
You got three seconds. Go!
你有三秒钟。开始吧！
Day and night are of equal length on an equinox, and yesterday was the autumnal equinox.
秋分时节昼夜相等，昨天就是秋分。
That`s your answer and that`s your shoutout.
这就是你的答案，你的大喊。
That means as of yesterday, it is officially fall in the Northern Hemisphere. The season runs until the winter solstice, the shortest day of the year, which will be on December 22nd, marking the official beginning of winter.
那意味着截至昨天，太阳正式进入北半球。秋分过后是一年中白昼时间最短的冬至，今年冬至的时间是在12月22日，正式标志着冬天的到来。
In the meantime, the farther north you live from the equator, the more you can expect cooler temperatures, shorter days and a vibrant change in foliage.
与此同时，你住的地方离赤道越往北方，温度将会更低，白天时间更短，树叶变化更具活力。
