NASA Research Team Reveals Moon Has Earth-Like Core

A team at NASA has discovered that the moon may indeed have a core very similar to earth's. By analyzing data from the 1960's and 70's, teams have uncovered many interesting findings. The moon possesses an iron rich core just like the earth. However, it differs in that the moon has a molten boundary layer around the core, measuring about 300 miles thick. Much of the evidence was gathered from seismic testing of things such as "moon quakes".

The full story can be found here:

With craters and volcanoes on Mars, this doesn't really surprise me. I wonder if the minerals found deep beneath the surface of the Moon are the same as well or if there are minerals that don't exist on Earth. If the core of the Moon is less hot as well, perhaps it will be possible one day to probe close to the core of the Moon which can tell us more about what it's like in the core of the Earth.

I think this find really is a tribute to our ever-improving state of technology. These data signals were generated by lunar seismic sensors that were planted over 3 decades ago. However, this data only made sense when combined with Dr. Weber's technique of seismogram stacking. As astronomers collect more and more data everyday, maybe we can expect that, as technology advances, we will be able to understand astronomical mysteries and phenomena in the very near future.

This is pretty interesting. I would never have thought the moon has a core similar to the earth. Makes me wonder how many other planets have an iron core, or moons of other planets for that matter.

This is a very interesting finding. The fact that the moon has an earth like core only makes us wonder what else is similar between the two that we dont know. It is incredible that this discovery was based off evidence from seismic testing from moon quakes
