Machinery that allows us to observe not only what exists in the sky

Over the years, telescopes have evolved from simple tools to complex machinery that allows us to observe not only what exists in the sky but also their content and properties. Given the evolving needs of man, telescopes have been advanced using technology and several limitations relating to nature, such as visibility, weather, etc have been overcome, sometimes resulting in outlandish designs. The results of these endeavours have allowed man to study the galaxy that he lives in more closely and understand the reasons behind why things are the way they are.
