Feature Guest: Jane Greaves

Remember that nursery rhyme, “Up above the world so high, like a diamond in the sky?” Well they were on to something, because it turns out diamonds – albeit nanodiamonds – are ubiquitous across the Milky Way galaxy. So-called diamond dust is even here in our own solar system. Today we’re joined at The Star Spot by Professor Jane Greaves, whose team made the discovery that unexpectedly solved a long standing astronomical mystery.
