Images captured by a NASA space monitoring satellite have confirmed that Earth is likely to come under attack from an alien strike force before the end of the century.
The images show aliens advancing in formation at a very slow pace, indeed. Presently, they are passing by Jupiter, but on course for the Earth.
The alien spaceships appear to be crab-like, and move sideways, left to right, for a long time, before advancing a very short distance, and then resuming their sideways movement, but in the opposite direction.
Although the invaders may never reach Earth, due to unforeseen asteroid or meteor collisions, NASA has warned the US government it should take steps to repel a potential attack, by installing button-press firing systems that are configured to military precision, all across the country.
Or a joystick version for those who aren't as nimble-fingered.
