Good, let’s go get the oil there.

“It’s a good thing the Moon doesn’t have any feelings to hurt. New research suggests it is actually 30 million years younger than anyone had thought, and that it is merely a ‘chip off the old block’ of Earth rather than being made up of the remnants of a Mars-sized body that slammed into Earth billions of years ago.”

Speaking of Mars, the red planet is the brightest it will be for quite some time in the night sky. Looks like a bright star with a yellowy-orange tint to it. Cool stuff.

Suddenly I am craving an RC cola about now...

Moon is younger and more Earth-like than thought

now keep thinking

I can see the headline now, “Atlantis found!”.

“…suggests that picture is not so simple.”

What a retarded statement.

Moon Is Younger And More Earth-Like Than Thought

Interesting. How young and earth-like is thought?

remnants of a Mars-sized body that slammed into Earth billions of years ago.

God to His angels: "Watch this. 8-ball into the side pocket!"

I thought the earth was only 6000 years old? </s>

I love science. Want to see more of it on FR.

Wonder why that is? I thought the moon was a piece of the earth to begin with.

I like this young Moon

New research suggests it is actually 30 million years younger... the Moon was thought to have coalesced from a disc of molten debris blasted off the Earth and the Mars-sized interloper... The researchers base their analysis on studies of an isotope of the metal tungsten in lunar rocks. That isotope, tungsten-182, is produced by the decay of two other elements: hafnium-182, which has a half-life of 9 million years, and tantalum-182. Tantalum-182, however, is not an intrinsic component of the Moon – it forms when energetic charged particles from space, called cosmic rays, slam into the lunar surface. Previous estimates of the Moon's age were based on tungsten measurements that did not subtract the effect of the decay of tantalum.

Previous estimates (and those described in this article) are not based on the tungsten measurements, they are based on the bias that the Moon *must have* formed from an impact on the proto-Earth by a Mars-sized object.
