This Alaska town won't see the sun for more than 2 months An Alaskan town has said goodbye to daylight for the next two months.

The sun rose and set in Utqiagvik, Alaska, formerly known as Barrow, for the last time for on Thursday for a period of over 60 days.

The small town located north of the Arctic Circle has entered its annual phase of darkness, known as polar night.

"Polar night is a normal phenomenon that happens every winter for Barrow (Utqiagvik), and any other towns inside the Arctic circle," said CNN meteorologist Allison Chinchar.

The occurrence takes place each winter because of the tilt of the Earth's axis.

"This tilt makes it so that none of the Sun's disc are visible above the horizon," according to Chinchar.

But that doesn't mean the town will be completely dark. Most daytime hours will go through periods known as civil twilight, said Chinchar.

"Think of what the sky looks like just before sunrise, or just after sunset," said Chinchar. "That is what they see for several






hours a day, from now until January 22, when the sun will "officially rise" again."

The town is not the only one in Alaska to experience this phenomenon, but it is the first on the polar night location list because of how far north it is.

If the life of a night owl is unappealing for the people of Utqiagvik, they can always look toward the summer when the opposite occurrence, known as a midnight sun or polar day, causes 24 hours of daylight.

这个阿拉斯加小镇将有2个多月见不到太阳

在接下来的两个月里，阿拉斯加的一个小镇就要告别白天了。 在阿拉斯加的乌特恰格维克，也就是以前的巴罗，60多天以来，太阳在周四最后一次升起和落下。

这个位于北极圈北部的小镇已经进入了每年一度的黑暗阶段，被称为极夜。

美国有线电视新闻网气象学家艾莉森·钦查尔说:“对于巴罗(乌恰维克)和北极圈内的其他城镇来说，极夜是每年冬天都会发生的正常现象。”

由于地轴倾斜，每年冬天都会发生这种情况。

“这种倾斜使得地平线上看不到太阳的盘面，”Chinchar说。 但这并不意味着小镇将完全黑暗。钦查尔说，白天的大部分时间都将经历被称为“文明黄昏”的时期。






钦查尔说:“想想日出前或日落后的天空是什么样子。从现在起直到1月22日太阳再次“正式升起”之前，他们每天都会看到几个小时的景象。

这个小镇并不是阿拉斯加唯一一个体验到这一现象的小镇，但它是第一个在极夜间拍摄地点名单上的小镇，因为它离北极有多远。

如果夜猫子的生活对人们没有吸引力，他们总是可以把目光投向夏季，当相反的情况发生时，即午夜太阳或极地日，造成24小时的白天。
