Why Summer Nights Barely Get Dark in Norway
In the far north of Norway, a summer night can look like the middle of the afternoon. At midnight, the sun may still hang in the sky. Families go for walks, kids kick a ball, and some people even mow the lawn. This is called the midnight sun.
The cause is the way Earth is tilted. Our planet does not spin straight up and down. It leans to one side as it circles the sun. In summer, the northern end of Earth leans toward the sun. Places very far north, in a region called the Arctic, are tipped so far toward the sun that it never fully sets. For weeks, the sun just circles low across the sky.
Winter turns the story around. When the northern end leans away, the sun stays below the horizon for weeks. The sky glows a soft blue for a few hours at midday, and the rest of the time is dark. People light candles and string up lamps to make the days cozy.
How do people sleep when it is bright at midnight? Many hang thick curtains over their windows. Some find that the long days give them lots of energy, and they stay up late to enjoy the outdoors.
