p.s. marvelous imaging of the E and G rings!

Cassini has shared images of Earth and Venus with us from Saturn, and the suggestion was made to find Mercury and Mars as "morning stars." but i wonder what Jupiter would look like from Saturn. Venus and Earth look awesome. Jupiter should look spectacular.
will Cassini be operational long enough to get a good viewing angle? Robert (Mar 17, 2013 at 9:42 AM):
This is both science and art combined. It never ever ceases to amaze me how brilliantly the Cassini Imaging Team continue to produce fascinating, mind-enriching, curiosity-engaging, and emotionally-gasping views.
It is profound to see a planet from the perspective of another planet. It adds a sense of familial closeness across the billion miles of space. This image (similar to the blue-dot one) adds to my understanding of what "system" means in the solar system. I am curious about the blue colour of the E Ring. Is that the same kind of dust scattering effect as Raleigh scattering in Earth's atmosphere? And if so, why isn't the G Ring in this image also blue? Is that a result of the viewing geometry here? Or is more to do with the rings being a thin plane rather than an atmospheric sphere? And, if it is a result of plane geometry, then why aren't there colour fringes or gradations in the G Ring? -- I guess that's because the rings are too narrow to show that effect. If the blue colour of the E Ring is indeed similar to the effect of Raleigh scattering, does this mean that this is the first ever image of the effect outside of a planet's or moon's atmosphere? jsc248 (Mar 11, 2013 at 2:00 PM):
My comment is Simply Breathtaking!

My rating would be '12'.

This too is amazing :)
The Cassini Spacecraft passed 'behind' Saturn looking towards the inner solar system through the rings when the planet Venus, some 1.44 Billion KM / 890 Million miles was spotted throuht the rings on one ocassion prior to being eclipsed & then again righ next to Saturn's limb just after. The Sun although appearing close by was eclipsed by Saturn. Both the Sun & planet Venus (Mercury, Earth & Mars too) appeared in front of the constellation of Cetus the Sea Monster, near the boundary with Aries the Ram. The bluish E ring is clearly visible. The E Ring is formed from ejected ice crystals from the south polar geysers on the Saturn moon Enceladus. The G Ring is a much fainter, narrower ring, appears to be a mixture of dust & ice particles. The G Ring appears to be crud knocked off the tiny 500 metre / 1,640 foot wide moonlet Aegaeon. |
