Today the Hubble Space Telescope people have found a new breed of sheep on Pluto, whose coats are bright blue and can jump up to a hundred metres off the ground.
The astronomers think that there must be alien farmers there, as there is grass and some larger sheep which look a bit like cows.
NASA and the European Space Agency is feeling very worried about the recent Extra Terrestrial life findings, and many believe it is only a matter of time before these aliens invade our planet.
NASA has begun talks with Wales to enlist a crack-team of Welsh farmers so that if the Plutonian sheep do invade, we'll be ready for them!
