  Apr 16, 2015 Saturn’s moon Mimas exhibits a significant libration. In past Picture of the Day articles, several moons in the Solar System were analyzed in terms of their electrical connection with their parent bodies. In particular, the discovery that Jupiter’s moon Io and Saturn’s moon Enceladus are exchanging powerful…

Plasma Contortions

  Apr 15, 2015 Rather than black holes, electricity should be considered.

As previous Picture of the Day articles point out, the constricted channel is known as a “Bennett pinch,” or “z-pinch.” Pinched…

Tempestuous Ariel

  Apr 13, 2015 Another moon with unmistakable signs of electric discharge impacts. The moon Ariel is pockmarked with craters ranging from five to ten kilometers across—almost undetectable in the image above—however, a few craters measuring 20-30 kilometers across are visible. The crater dimensions might seem small, but considering Ariel’s…

Desolate Dione

  Apr 10, 2015 Saturn’s fourth largest moon indicates that plasma events of some kind once clawed into its surface. The first images of Dione revealed a moon whose surface appeared to be dominated by bright “wisps” that wound around its face. Later, when higher resolution pictures were decoded, the wisps were…
