Light Pollution

Light pollution occurs when powerful electric lights around us stop us seeing the stars in the night sky. Amazingly, many children growing up in big cities today have never seen the night sky properly because of the increase in light pollution. And it is not only in cities – people living in the country are also affected by lights from nearby towns. It is a problem for those simply trying to enjoy the stars, and for serious astronomers as well. However, one university in the UK has come up with an interesting solution. It has built a telescope in the Canary Islands and allows schools to use this via the internet.
