Have you ever slept under an open sky and realized how beautiful the night sky appears? Once there was a time when our ancestors just saw the beautiful sky and framed interesting stories about it. None of them knew about the beautiful world lying besides this earth. The stars were considered to be a decoration which merely increased the beauty of the night sky and no one was even aware of any other planets besides the earth.
But today we earthlings are not only aware of other planets and stars but have also stepped on them. All this started from the discovery of a then considered mere instrument telescope which today hides behind its lens the treasure of beauty of the universe. Today earth owns many powerful telescopes who proudly marks their presence on earth through the demonstration of the knowledge of earthlings about the space and universe. Given below are the list of few of greatest telescopes of the earth who have dived us deep into the beautiful night sky .
