Totally carbonaceous, dude!
On Sunday, 28 September 1969, a meteorite shower fell to earth around the town of Murchison in northern Victoria.
The Murchison meteorite belongs to a rare class of meteorite called a carbonaceous chondrite which retain chemical properties from their time of formation – 4.56 billion years ago. These molecules demonstrate that the simple chemical building blocks necessary for life on Earth are present in outer space, and scientists have theorised that similar meteorites may have ‘seeded’ life on earth.
Our design for this commemorative stamp issue features a map of the fall site overlaid with a hexagonal pattern representing the amino acids founds in the rock.
