Saturns Rings from the Inside Out
What do Saturn's rings look like from Saturn? Images from the robotic spacecraft Cassini are providing humanity with this unprecedented vantage point as it nears the completion of its mission. Previous to Cassini's Grand Finale orbits, all images of Saturn's majestic ring system were taken from outside of the rings looking in. Pictured in the inset is the remarkable video, while the spacecraft's positions are depicted in the surrounding animation. Details of the complex rings are evident as the short time-lapse sequence begins, while the paper-thin thickness of the rings becomes apparent near the video's end. The featured images were taken on August 20. Cassini has only a few more orbits around Saturn left before it is directed to dive into the giant planet on September 15.

The city of Athens flourished in the 400s and 300s BCE, setting the course for modern European civilization and eventually for democracy’s re-emergence. Even when her power waned, Athens remained the cultural and educational center of the Mediterranean until the 500s CE. And the agora, or marketplace, was the center of city life throughout this time. In it was built beautiful and functional public buildings, first by proud city citizens, then as gifts from Greek kings and eventually Roman emperors.
Since the 1930s, modern excavations have been underway to study where the agora once stood. And they have an excellent website, with an interactive map of what has been recovered and discovered, so far, of the ancient Athenian agora.

Sometimes tornadoes pick up fish while traveling over water and carry them over land, where the fish rain down. These “fish showers” have been happening for thousands of years. The Roman writer Pliny the Younger described a “fish shower” that happened in the 1st century CE!
