NASA recently put this picture on it's website. It was taken by the NASA probe Cassini on 11/04/2015 (which is orbiting Saturn, and which is currently in it's last stages of life, making a number of grazing flybys by the rings of Saturn, prior to crashing down into the planet's atmosphere).
This picture is of one of Saturn's moons, known as Thethys, (Tehthys was also the name of one of the earth spanning oceans in a different geological era of the earth.)
In this picture a large dent is clearly visible on the right side of the moon.
According to NASA this was probably formed by a large impact of another object.
However, for those of us who are more into science fiction, it looks more like some fossilised form of the Death star from the star wars universe:
Tethys is not alone, years prior to this picture the Cassini probe had already pictured a different saturnian moon, less than half the size of Tethys, showing very similar features: Mimas:
Also, years prior to Tethys Cassini had already pictured yet another Saturnian moon: Lapetus, again showing an ominous similarity.
These things might have appeared a joke untill last year. When in Star Wars Episode VII, we learned about a new evolution of this weapon: The star destroyer base, which no longer was an artificial moon, but a real planet which had been hollowed out, and turned into a weapon which would suck the energy from a star, and use it to destroy entire solar systems...
the largest "impact crater" according to NASA, is to be found not on any saturnian moon, but on a planet, a planet which is conveniently placed very close to the sun: Mercury...
The above is a false color image, clearly showing the massive crater at the right top,...
So all of these scientific discoveries really beg the question. Are there multiple objects in our solar system showing massive impacts? Or was our solar system used as a staging ground for planetary weapons, starting with Mimas, moving on to Tethys, before completing this experiment in Lapetus, after which the technology finally made it's last leap, and Mercury was put into place close to the sun, ready to drain it, and destroy a solar system with it?
And last but not least, if we agree they were weapons, what happened to the civilisation that built them?
