His eye to the telescope, Galileo was first to admire the craters of the Moon and the rings of Saturn. Most of us would need lessons on how to build a telescope, but Isaac Newton improved his with light collecting mirrors allowing him to see far beyond anything that had been seen till then. Ancient Egyptians and Aztec were already fascinated by the wonders of the skies but only had their eyes to study them... In the 17th century, the introduction of the astronomy telescope opened whole new perspectives. The refractor telescope of the early days already provided a better picture of the universe around us... today, the hubble space telescope gathers striking images that give us all a glimpse of eternity. Watching the sky still captivates and has become a hobby to many. Eager amateurs will choose their tool carefully among a wide selection of models and providers such as the celestron telescope, the bushnell telescope or the orion telescope. A large range of prices gives us all a chance to have our own peak at the mysteries of space, and perhaps get a better understanding of our world by watching others. And for those lacking the patience, hubble space telescope images will still provide much food for thoughts and reasons to marvel.
