The Allende meteorite fell on the 8th of February 1969 in Chihuahua, Mexico. Its fall was observed as a huge fireball that lit up thousands of square miles of northern Mexico and southwestern United States.
The meteorite broke up in many pieces, with a total recovered mass of 2 tonnes. The biggest pit it made is only 60cm across and 15cm deep.
The Micro-CT scan shown reveals different components of the meteorite: blue = micrometre-fine-grained rocky matrix, green = rocky chondrules up to 1mm, and yellow = small metals and sulfides less than 1mm.
All components formed in the solar nebula prior to the formation of earth, recording the conditions of early solar system formation.
