This stunning view of Saturn is one that can never be seen from Earth; it was taken by the Cassini spacecraft, still orbiting the huge ringed planet, from high above the equatorial plane on October 10, 2013. Only in such a view can the planet itself be seen as separate from the surrounding rings. This composite image was made from 36 individual images. Beautiful!
Last Friday, a remarkable thing happened, which received a lot of publicity, especially for space fans: the Earth had its photo taken – from Saturn! The Cassini spacecraft took the images, which were used for The Day the Earth Smiled event, showing the Earth as a very tiny blue speck in the distance, with Saturn and its rings looming in the foreground. Zooming in closer, the Moon can also be seen. How cool is that? But that’s not all… although it didn’t seem to get as much attention, the Earth and Moon also had their picture taken from Mercury, by the MESSENGER spacecraft, on the same day!
Something remarkable is going to happen next Friday, July 19, 2013. On that day, the Earth is going to have its picture taken, but not just from an orbiting satellite, from Saturn. The Cassini spacecraft, still orbiting the ringed planet, will take images of Saturn and all of its rings during an eclipse of the Sun. This has been done twice before, but this time, the view will include another tiny, far-away blue speck – the Earth, in natural colour.
The Cassini spacecraft has taken thousands of images of Saturn and its moons, and this one is another beauty. Titan, Saturn’s largest moon, and the one with the methane rain, rivers and lakes, floats in space out beyond Saturn’s rings.
Saturn’s rings are one of the most beautiful sights in the solar system. They are an amazing planetary phenomenon – countless bits of rock, ice and dust orbiting the planet in relatively paper-thin rings, which, when seen from above, kind of look like a giant vinyl record (remember those?). Saturn’s many moons can affect the rings’ appearance due to their gravitational pull. Now, new research shows how Saturn itself can do this also, essentially “shaking” its rings.
Meteors flashing across the sky are a common sight here on Earth, but of course they are not limited to only our planet; these bits of rocky debris, smaller pieces of asteroids and comets known as meteoroids, can be found just about everywhere in the solar system (becoming meteors when entering and burning up in the atmosphere). Now, the Cassini spacecraft has observed similar impacts occurring in another very different and far-away place: the rings of Saturn!
