Ryugu's dust is really old

 

Recent results from analysis of the dust brought back to Earth by the Japanese satellite Hayabusa-2 indicate that the dust is old.

Really old.

Essentially older than Ryugu and the entire Solar System.

I don't know about you, but that impresses me.

You've got to be impressed with the technology, right?
