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 be habitable after all.
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.
When Pluto was first discovered, it wasn’t known if it had any moons, and it was already a tiny world itself, smaller than Mercury (which doesn’t have any moons). As of last year however, five moons have been found orbiting Pluto! Now a new study announced today suggests that there may be up to ten more little moons or moonlets keeping Pluto company in the outer fringes of the solar system.
