Date of discovery: March 2012 (although the photo if from 2009)
Location of sighting: Earth's Moon
Yes NASA did drop a small nuclear bomb on the moon in 2009, I personally watched it live on the internet with my students. Also the NASA Ames Research Center does get intel on such structures because one is being used by the USMC as an America base.
Person discovering it states: "Now that's a huge cat left out of NASA's bag. The smoking gun evidence that NASA knows about the presence of extraterrestrial bases on the Moon and ultimately bombed one these structures during the LRO/LCROSS mission in 2009, allegedly carried out to seek water in the crater Cabeus."
Maybe thats why nasa are no longer welcome in space
Nasa accidentally confirms what we have known all along, that there are indeed structures on the moon. In this picture taken at the Nasa Ames Research Centre, we can clearly see two possible structures, one is quite clearly a square shaped building, the other to the right looks like a triangular shaped structure or maybe a bridge, its arched in any event. Is this the smoking gun, absolute proof that NASA has been lying to the world? People in the pic are:
