Older than the sun, the meteorite scientists call ‘the real time machine’
The discovery suggests that while the first light from the sun fell on the fledgling Earth, as the dinosaurs rose and died out and humans gained dominance, the meteorite was hurtling around the heavens on a billions-of-years-long journey destined to terminate with a thud in Yukon territory. Researchers at Nasa’s Johnson Space Centre in Houston examined a two gram fragment of the meteorite and focused on tiny, hollow, carbon spheres embedded within it. Each “globule” measured just a few thousandths of a millimetre across.
Interesting stuff.
