This piece of rock is 4.4 BILLION years old. DAYUM!
esearchers involved in the discovery said that the discovery was of high scientific value. Earth's crust formed relatively quickly after the formation of our planet, and this little gem is a remnant of the original crusty crew. According to the University of Wisconsin scientist who led the investigation, John Valley, the survival of the crystal suggests that the early planet was not quite as harsh a place as commonly accepted in the scientific community. It lends support to the "cool early Earth" theory, which says that hydrosphere and liquid water existed before 4.3 billion years ago.
The unassuming little point of light in the centre of this image is something really quite special. Just 6000 light years away, it's the oldest star ever discovered. Going by the designation of SMSS J031300.36-670839.3, this star is older than the very galaxy which we live in, and formed when the Universe itself was still young.
