I love a bit of space news, especially when it involves little Pluto.
Scientists have developed a simulation to explain how a 4-kilometre-deep canyon on the planet's surface slowly trapped very cold gases from the atmosphere. These gases - nitrogen, carbon monoxide and methane - eventually condensed into ice.
To see if their simulation is correct, they've made a prediction of what will happen to the ice on Pluto over the next 10 years. I'm quite impatient, so for me it's going to be a long wait to see if they're right.
