The rings of Saturn are about 10 meters thick. Yet they light up the solar system with wonder and awe. In this NASA image, the Earth is seen from the Cassini spacecraft through a gap in the rings of Saturn. It’s an encore of the famous Pale Blue Dot image of Earth seen from 6 billion km away back in 1990. In this new image, if you look closely, Earth’s moon is also visible. As astrophysicist Neil deGrasse Tyson might say, this one photo provides a substantial cosmic perspective. We are tiny. We are alone. This is the only home we have.
