Saturn’s largest moon Titan is one of the most Earth-like places in the Solar System, as least in terms of appearances, with its seas, lakes, and rivers (of liquid methane/ethane). But it is similar in another way as well, with vast stretches of huge wind-blown dunes in its equatorial regions. Only Earth, Venus, and Mars are known to have such dunes… Read More
It wasn’t that long ago that Earth was thought to be the only place in the Solar System capable of having liquid water oceans, but now we know of several moons that do as well, including Europa and Enceladus, and likely Titan and Ganymede as well. In all these cases, the oceans are below ground, … Read more
Saturn has dozens of moons, ranging from the largest, Titan, which is larger than our own Moon, to small asteroid-sized objects. Now it seems that the Cassini spacecraft may have witnessed the formation of yet another moon, actually seeing the process as it is happening.
The names have now been chosen for the two most recently discovered moons of Pluto, it was announced last Tuesday by the The International Astronomical Union (IAU). The fourth and fifth known tiny moons are now known as Kerberos and Styx.
The outer solar system was once thought to be not much more than a frozen wasteland, at least in terms of the many moons orbiting the gas and ice giant planets. But with the intriguing discoveries made by robotic probes such as Voyager, Galileo and Cassini, we now know differently.
Not all that long ago, it was considered very unlikely that life could exist anywhere else in the solar system, apart from maybe Mars. A variety of robotic spacecraft missions, however, have changed scientists’ views; there are indeed a handful of other worlds in our own cosmic backyard which it is now known could potentially … Read more
Europa is a fascinating little world, a moon with an icy crust and a subsurface global ocean. The environment is similar to the ice-covered waters at the Earth’s poles. Now scientists think that there may be another feature which is also found on Earth – huge frozen spikes of ice on the surface.
