I’ve been getting emails about these “structures” on the moon.
As you can see, the image is courtesy of NASA and Google Earth software. It comes from the second link noted below.
Sorry, folks, these are not artificial structures. There is no alien moon base.
This discussion from the Discover Magazine blog goes through what they are and why, with lots of illustrations. They digital imaging artifacts (i.e., the objects are created are residual effects from the camera, light, imaging process, etc.).
As good as that link is, this one is even better (it’s referenced within the first one). It takes you step-by-step as to how these images happened. It even has motion gifs illustrating how the are recreated and manipulated. Really cool stuff.
People must think aliens who wanted to keep their secret bases on the moon secret are idiots. First of all, if the USA thought there was an artificial structure on the moon, it’d nuke it now and ask questions later. Anyone who observed US foreign policy for half a decade would take pains to at least, you know, dim the lights.
Oh sure, they’ve invented interstellar travel, but they haven’t invented camouflage netting. Makes sense.
