Protesters set up a fiery roadblock in the Abobo area of Abidjan March 3. Ivorian security forces and tanks, backing incumbent President Laurent Gbagbo, opened fire on a rally of hundreds of unarmed women in Abobo. Seven protesters were killed. The massacre was the latest of clashes that have erupted in the west African country since a disputed election on Nov. 28 that Alassane Ouattara won, according to international election groups, regional African organizations, and most nations. About 300 people had been killed in the violence, and there are fears of a return to civil war.

Explanation: How thin are the rings of Saturn? Brightness measurements from different angles have shown Saturn’s rings to be about one kilometer thick, making them many times thinner, in relative proportion, than a razor blade. This thinness sometimes appears in dramatic fashion during an image taken nearly along the ring plane. The robot Cassini spacecraft now orbiting Saturn has now captured another shot that dramatically highlights the ring’s thinness. The above image was taken in mid January in infrared and polarized light. Titan looms just over the thin rings, while dark ring shadows on Saturn show the Sun to be above the ring plane. Close inspection of the image will show the smaller moon Enceladus on the far right. Cassini, humanity’s first mission to orbit Saturn, currently has operations planned until 2017.

The Cassini spacecraft looks past the cratered south polar area of Saturn’s moon Rhea to spy the moon Dione and the planet’s rings in the distance.
This view looks toward the south polar area of the anti-Saturn side of Rhea (1,528 kilometers, or 949 miles across) and the Saturn-facing side of Dione (1,123 kilometers, or 698 miles across). North on the moons is up.
This view looks toward the northern, sunlit side of the rings from just above the ringplane. The rings, closer to Cassini than Dione is, obscure the view of the south of Dione.
