Seven Wonders of the Universe

The Seven Wonders of the ancient World is the first known list of the most remarkable creations of classical antiquity; it was based on guidebooks popular among Hellenic sightseers and only includes works located around the Mediterranean rim and in Mesopotamia. The number seven was chosen because the Greeks believed it represented perfection and plenty, and because it was the number of the five planets known anciently, plus the Sun and Moon. In the sky above our head, there are wonders too numerous to count. But what could we choose as the seven most remarkable objects visible, either with just our eyes or with a simple pair of binoculars or a small telescope? Seven objects which we might call, “The Seven Wonders of the Universe.”
