For the last decade, astronomers have struggled to figure out what was causing the mysterious massive cyclones seen on Saturn. Now, new research has revealed that multiple small thunderstorms are to blame.
We certainly know how long our own day is, and Mars is not much longer (24 hours and 40 min). The closest planet to the Sun, Mercury's own incredibly long day lasts more than 1,407 hours. What's interesting, however, is that astronomers know all this with near certainty. That's not the case for Saturn, on the other hand, whose day length has remained something of an enigma.
It is well known that Saturn's moon Enceladus harbors a subsurface ocean, but what scientists have just discovered are signs of current hydrothermal activity that may be warming up its seas enough for life to survive.
Astronomers are shamelessly drooling over a new set of naked photos, but it's not exactly what you think. The photos, snapped from an ideal vantage point by the Cassini spacecraft, have managed to reveal that Saturn's moon Titan looks far more like the surfaces of Venus or Mars than experts expected, at least when it's stripped down to its birthday suit by buffeting solar winds.
Saturn's moon Titan is home to one of the most intriguing mysteries of our solar system - the "magic island" of the Ligeia Mare sea. Now, a new flyby of the Cassini spacecraft has revealed that another sea may boast similarly intriguing island-like features.
After nearly a year, NASA's Cassini spacecraft has spotted what looks like an island in the middle of Titan's largest hydrocarbon sea once more. Despite the fact that Cassini engineers know where to look, the island seems to show itself only sporadically, its mysterious vanishing act earning it the name "Magic Island."
The long-running Cassini orbital Saturn mission has revealed that there are hundreds of hydrocarbon lakes and seas located all over Saturn's moon Titan. Now new observations have led researchers to believe that they can explain, at least in-part, how methane rainfall replenishes these liquid landmarks.
NASA's Cassini spacecraft has identified 101 geysers of water vapor and ice particles dotting the surface of Enceladus, one of Saturn's many moons.
After orbiting Saturn and its respective moons for a decade, NASA's Cassini spacecraft is entering the last phase of what the Cassini team has been calling its "extended-extended mission." This final phase has been coined "the Grand Finale" by the general public, and will end with Cassini throwing itself into Saturn's fiery atmosphere.
Titan, Saturn's largest moon, is home to a mysterious "magic island" that appears and disappears into the satellite's pungent chemical seas. Now, researchers have outlined their best guesses as to what this island may actually be.
NASA's Cassini spacecraft has released a spectacular backlit view of the planet Saturn and its rings.
