The Cosmos #1:
The dynamic and vibrant nature of the cosmos was only recently been revealed (during the last century or so) through increasingly advanced telescopes and better means of collecting data. For most of human history, humans saw the sky as constant and static. It was one of the few constants in a world that seemed hazardous and unpredictable. Of course, when comets passed over the heavens or whenever a supernova occurred, creating a new brightest object in the night sky, the ancient astronomers were perplexed and offered religious or superstitious reasons for their passing. Because we are used to a calm, constant night sky, the passing of comets (which disturbed this constant nature) were seen as symbols of war and famine. For example, Marcus Manilius, a Roman astrologer, wrote that “Heaven in pity is sending upon Earth tokens of impending doom”. Today, we can admire the beauty of the universe without the clouds of superstition obscuring our view (we have to worry more about light pollution!) I hope that you will enjoy this collection of wonderful images reflecting the dynamic nature of the cosmos.
