I handled this incredible meteorite slice today, it’s in the archives of the royal institution and the curator, Charlotte , told me that it is about 4.5 billion years old, and almost certainly so far away that it must come from another galaxy. not only that, but it’s composition 92% iron and 8% nickel, means that it also comes from the heart of a planet. I’m stunned with the age and distance it has come from. I feel so small and insignificant.@T@The Royal Institutionm#meteoriteo#oldestg#geologyt#thelondonspyd#davidharrya#ancienta#astronomyl#londonguides#science
