Die beliebte Mehrwertsteueraktion von MediaMarkt und Saturn ist zurück, diesmal zur Fußball-EM! ⚽️🎉 Aber Vorsicht: Echte Schnäppchen sind seltener geworden.
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.
