Found A Rectangular Thing On The Moon....


Recommended Posts

No, it's not an alien spacecraft, just as usual, an attempt to translate for "popular science" via simplification that let's folks misinterpret what's already a pretty cool discovery:

 
Scientists have found a nearly square peg underneath a round hole—on the moon. Several kilometers below Oceanus Procellarum, the largest dark spot on the moon’s near side, scientists have discovered a giant rectangle thought to be the remnants of a geological plumbing system that spilled lava across the moon about 3.5 billion years ago. The features are similar to rift valleys on Earth—regions where the crust is cooling, contracting, and ripping apart. Their existence shows that the moon, early in its history, experienced tectonic and volcanic activity normally associated with much bigger planets.

This of course builds on the discovery a few years ago that the Moon still has a molten core.

 

 

We may go to the moon, but that's not very far. The greatest distance we have to cover still lies within us, :phones:
