Why should Mars get all the attention?

While scientists and amateur astronomers are scratching their heads over a "mystery rock" that popped up near the Mars rover Opportunity, there's also a puzzling object that fans of Google Moon are talking about.

It can be found on the Google Moon viewer at coordinates 22° 42'38.46N and 142° 34'44.52E. Google Moon uses Google Maps to show satellite images from the moon.

The wedge-shaped object, which has seven circular points evenly arranged in a right angle, doesn't look like anything that would naturally appear on the lunar surface, observers say.

It was discovered by paranormal researcher WowForReel and posted in a YouTube video, Tech and Gadget News reported.

Since the object is apparently huge, it's probably fitting that speculation over what it could be is trending to the grandiose: "It's possible it is some sort of moon base used as a facility for storing and launching alien 'UFO' spacecraft," said Tech and Gadget News

Others speculate it could be a partially buried spaceship, the Daily Mail reported.

It's also possible that in the universe's nearly 14 billion years of existence, an earlier intelligent civilization passed our way, wrote us off as "a hopeless case" and abandoned its observation post on the moon, said Catholic Online.

"Or, it could just be a crater with the seven points caused by reflections of boulders or by other surface features, in which case all of this could be chalked up to the human brain's predilection to see patterns where none truly exist," Catholic Online said.

In an online forum, one commenter said, "2014 and every picture ever of anything like this is blurry. Always blurry." 

Another noted, "The moon is littered with Saturn V remnants and other space debris. Would have to rule out any of those before speculating on anything extraterrestrial."
