I had a methane (CH4) filter with me last night, so I took two pictures of Saturn (on a really windy night with dodgy seeing!), one without the filter, and one with it in place. Can you see how the rings are brighter than the planet in methane? Saturn appears dark at this wavelength because methane gas absorbs almost all of the sunlight falling on the atmosphere. However, the icy rings don't absorb sunlight leading to the unusual appearance of Saturn in the image. #saturn#NewZealand
#PPOD: To end our week, we look back at this beautiful picture of Titan and Saturn taken by NASA's Cassini spacecraft on May 22, 2015. Processed using calibrated near-infrared (MT2, CB2) filtered images. Credit: NASA/JPL-Caltech/SSI/CICLOPS/Kevin M. Gill
#PPOD: Mimas drifts along in its orbit against the azure backdrop of Saturn's northern latitudes in this true-color view. The long, dark lines on the atmosphere are shadows cast by the planet's rings. At the bottom, craters on icy Mimas (398 kilometers) give the moon a dimpled appearance.

Well, in this case it is. Back in 2003, #Saturn's moon Titan passed in front of the #CrabNebula. Chandra was on the spot, catching the transit as it happened. Astronomers were able to see the shadow cast by Titan, and used the size of that shadow to measure the extent of Titan's atmosphere.
A great result, demonstrating the power of the Dark Side!
New research has revealed huge “tiger stripe” fault lines on Saturn’s moon, Enceladus. How did they get there, and is there life lurking beneath the moon’s icy shell? Live Science has more: https://flip.it/.4uXWY #Science#Space#Saturn#Astronomy

[#ActuScience@IRAP ] A young IRAP PhD student formulates a new #theoretical model of the giant #magnetospheres of the planets #Jupiter and #Saturn: "By considering only the global motion of the #plasma (coming from the moons #Io and #Enceladus), it is possible to understand it simply as... a competition between various rotation resistances!"
