Black dome city found on Ganymede on May 2018

On May 4, 2018, Scott C. Waring, ufologist, found a black dome city on Ganymede, a moon of Jupiter, in Khensu crater.

He explains:

I found this black dome city on one of Jupiters moons today. Its located on the moon Ganymede and is called Khensu crater, but clearly it is not a crater, but a semi-transparent domed city. Much like the black eyelids of the grey aliens, this material is made this way to allow some light to pass through, but to filter dangerous radiation from the sun and universe. Also, it may have been created by the greys themselves.
