Blue Dot Geology

What is Blue Dot Geology?

In 1990, NASA’s Voyager 1 space probe captured a photograph of Earth from across the great expanse of space near the edge of our solar system, about 3.7 billion miles away. From that distance, this gave us a new perspective of Earth and life on it. The apparent size of Earth covered less than 1 pixel in the entire photograph (provided by Wikipedia) but highlighted the significance of our existence. Carl Sagan described the pixel as a “pale blue dot” and has since been a historical archive. In the photograph (right), the blueish-white speck is located almost halfway up the brown band on the right. Are you able to find our planet?
