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. Current in Space Simon explains a tantalizing find: 30 binary stars that have somehow been ejected from their home galaxies! Then Amelia and Tony report on a bizarre discovery: a star that's apparently the merger between two white dwarfs! About Our Guest Jane Greaves is Professor of Astronomer at Cardiff University in Wales. She is the recipient of the 2017 Fred Hoyle Medal from the Institute of Physics of London. In 2008 her team took the first direct image of a proto-brown dwarf candidate. Greaves uses textile art to communicate her passion for astrophysics with the public.
