Scientists have discovered the oldest piece of earth ever found. This crystal, called a "Zircon," is 4.4-billion years old. That's according to new findings published Sunday in the journal "Nature Geoscience." The crystal is microscopic, roughly 400 micrometers long, or about the size of four human hairs. Scientists say the crystal is red... but turns blue when bombarded with electrons used to study it. This piece of crystal was first uncovered back in Perth, Australia in 2001. The data is telling us more about the planet too. Scientists say the crystal suggests the earth cooled faster than previously thought, and could have contained water 4.4-billion years ago and possibly even earlier in life.
