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.
Hurricanes are an incredible force of nature, and these huge rotating vortexes of wind are an amazing sight when viewed from space. But Earth is not the only planet that has hurricanes, and there is one on Saturn that dwarfs any on our own planet. Now, the Cassini spacecraft has taken more breath-taking colour images of this colossal wind storm.
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!
The Cassini spacecraft has been orbiting Saturn for a long time now, taking stunning images of the giant planet and its rings and moons. Some new images, released today, show a different world though, far across the solar system and much closer to the sun -Venus.
Apart from being composed of liquid methane instead of water, the rivers, lakes and seas of Saturn’s moon Titan are amazingly similar in appearance to those on Earth. The hydrological cycle is also very similar, with Titanian rain replenishing them.
The Cassini spacecraft has sent back thousands of beautiful photographs of Saturn and its moons, but this latest one has to rank as one of the best. This view of Saturn, as it is backlit by the Sun, is magnificent, almost surreal looking. And it’s real. In the lower left, two of Saturn’s moons can also be seen as small dots; Enceladus is closest to the planet and Tethys is a bit farther out. Simply breathtaking…
Want to go river rafting on Titan? The largest moon of Saturn is the only other place in the solar system known to have rivers, lakes and seas on its surface. Appearance-wise, they are eerily similar to their earthly counterparts, but are composed of liquid methane instead of water, in Titan’s extremely cold environment. Now, the Cassini spacecraft has found the largest Titanian river system yet, similar to the Nile River on Earth, as announced on December 12, 2012.
