The night sky is full of stars. If you live in the city, it can be hard to see all of the stars because there are so many lights shining toward the sky. Lights from the gas station on the corner, the sky scrapers down the block, and the apartment building next door can make the sky so bright that you can't see as many stars. If you live in the country, you can see the night sky with layers of stars. It's easier to see them when you live in the woods or near a field because there aren't as many other lights around to block the view. On a clear, dark, cold night you could get dizzy counting all of the stars! Whether you live in the city or in the country, star gazing can be a great pastime. It's interesting to watch the sky change throughout the seasons of the year.
