Time for the Shoutout.
大喊時間到了。
What occurs when the sun crosses the equator, making day and night equal length the world over?
當太陽穿過赤道時會出現什么,使得全世界白天和黑夜一樣長?
If you think you know it, shout it out.
如果你知道,就大聲喊出來。

Is it an: (a) Eclipse, (b) Solstice, (c) Spectra, or (d), Equinox?
是:(a) 日食 (b)至日 (c)光譜 (d)秋分?
You got three seconds. Go!
你有三秒鐘。開始吧!
Day and night are of equal length on an equinox, and yesterday was the autumnal equinox.
秋分時節晝夜相等,昨天就是秋分。
That`s your answer and that`s your shoutout.
這就是你的答案,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.
那意味著截至昨天,太陽正式進入北半球。秋分過后是一年中白晝時間最短的冬至,今年冬至的時間是在12月22日,正式標志著冬天的到來。
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.
與此同時,你住的地方離赤道越往北方,溫度將會更低,白天時間更短,樹葉變化更具活力。
