The evidence is mounting that our solar system is rife with oceans. Last week, scientists reported that Pluto could have an insanely deep liquid water swimming pool beneath its surface, and on Monday, NASA revealed new evidence for geyser activity on icy Europa. Now, another frozen moon is poised to join the club of…
This is really cool: the New York Times has put together a really astounding interactive feature that lets you explore Saturn and its moons through NASA’s probes.
This week, the Cassini spacecraft made its fifth and final flyby of Dione, Saturn’s fourth-largest moon. This image, in which Saturn and its rings can be seen looming behind the moon, was captured in the leadup to the mission’s last close approach, on August 17, 2015.
Cassini’s epic mission to Saturn is coming to a close with a spectacular finale of daring flybys and swooping encounters. The beginning of the end happened today with the last targeted flyby of Dione, the icy moon of towering cliffs and dizzying canyons.
The Moon may be Earth’s kid brother, but Saturn’s moons seem more gnats on an elephant in this incredible image captured by the Cassini probe.
The pock-marked surface of this spherical chunk of rock looks a lot like images of our own Moon—but in fact, this is much, much further away.
The moons of Saturn and Jupiter are just getting more and more intriguing. While many of those far-flung satellites might contain liquid oceans, a new report indicates that Dione, one of Saturn's icy moons, is surrounded by a thin layer of oxygen.
The little grey ball is Dione, the third largest Saturn moon. The large brown sphere with the ethereal haze is Titan, the largest. On the background, that's Saturn and its rings. Never an astronomy picture looked so painterly to me.
Since 2004, NASA's Cassini orbiter has been collecting data on Saturn, its rings and its moons, capturing breathtaking images of them all as it courses through space.
Enceladus is home to one of the solar system's most incredible hotspots, churning out 15.8 gigawatts of power. It's even more proof that there's a liquid ocean hiding beneath the ice...but scientists have no clue what's creating all that heat.
The universe has so many dazzling sights that it seems silly to waste time on optical illusions. But some are just too amazing to ignore, like this shot of Saturn's moons Dione and Rhea seemingly morphing together into one mega-moon.
