The News! Landing on a comet!

Little spaceship - a probe - lands on a cometFor the first time in history. 



Comets look very special, even mysterious. They glow or shine if they are close to the Sun. Everybody knows it is a comet because they have that long tail. 

But what a comet is made of? Is it ice, rock or something else? Scientists wanted to find out and they built the probe. 

It was a long process and the journey took about 10 years! That means that the comet is very very far! Now the probe is exploring the comet - it's drilling the surface, testing the chemicals and so on - and ... posting the news on Twitter! That's amazing, isn't it?
