Earth's Core Contains Vast Amounts of Sulfur

 Here is an interesting article that seems to hold up the formation of the moon by a collision between Earth and a near Mars sized asteroid.

Apx. 1700 miles under your feet, Earth's core begins. Why should we be interested in this? Well due to the depth and heat, it is impossible to observe or even measure the composition of the core directly.

But thanks to an international group of researchers who developed an indirect geo-chemical methods to show core composition.

Until quite recently it was believed that Earth's core consisted of an iron / nickel amalgam. Due to the core's size it has been suspected that the core contained other lighter elements, such as sulfur, silicon, oxygen and carbon and the new method of imaging the core have proved that out.

Earth's core contains vast amounts of molten sulfur. 10X more than in the rest of Earth or better than 10% of the mass of the Moon!

So when you are told that brimstone lies just under your feet - well in a certain context -   they are not to far from the truth!

The Moon has an Earthlike core?

From Discovery.com and Science Now comes news that researchers have discovered a here to fore unsuspected Luna characteristic.

During the Apollo Luna missions during 1969-1972, astronauts installed Passive Seismic Experimental packages. Four in all. The sensors were put in place to record motions of the Luna surface due to moon quakes and other activities. These impacts generating sound waves which were received and archived until late 1977. Recently, seismologists took another look at data collected by these four sensors. Using seismic analysis equipment with the Apollo data, scientist were able to craft a picture of the moon's interior.

Those models turned out to be pretty accurate leading the researchers to conclusions that they were not prepared for. Because it seems that the center of the Moon is very much like that of Earth!

From the article:

• The new research confirms the existence of a solid inner core and liquid outer layer, similar to Earth's. Unlike Earth, the moon also has a partly melted, mushy layer over that.
• The study supports the commonly held theory that the moon formed after a large object smashed into Earth about four billion years ago, creating a cloud of debris that gradually coalesced into our satellite companion.
