【Shocking】Do you still remember such a night sky?

I was shocked by this set of photos! Such a brilliant starry sky could only be seen at my grandfather's house in the country when I was a child. After I moved to a big city, such a sky disappeared from my life. The following set of pictures come from the winning works of the 2010 Astronomy Photographer of the Year competition. Each picture records the beautiful night sky and the wonders of nature. Experiencing such a visual impact, shouldn't humans reflect on it? Loving our environment is more than just a slogan!
