Carnival 80

Ethan hosts the 80th Carnival of Space, a veritable feast of astronomy posts. In other news, the Cassini space probe has just completed a 47th encounter with Saturn’s moon Titan. Via Universe Today (see sidebar and visit daily for high-quality articles) I found this excellent link, “25 Tips for the Frugal Astronomer.”

Above, Cassini goes down-orbit from shepherd moon Prometheus to catch the F Ring in twisty, smoke-like shapes.
