Our observatory has just received a sample of the Allende meteorite from the collection of the department of earth & atmospheric science of the University of Alberta. This meteorite which landed in the locality of Pueblito de Allende in Mexico in 1969, is a carbonaceous chondrite type. It is composed of iron, rocky material and small mineralized spheres within the rocky matrix, called chondrites. Now, for the Little Bang theory. This theory concerns the formation of stars and planetary systems in the galaxy. It proposes the explosion of giant stars as the precursors of stars formation. By compressing the galactic cloud of dust and hydrogen gas, the supernova’s shockwave facilitate the gravitational collapse into stars. But like all theory, proofs are always welcome. The Allende meteorite provided a proof supporting this theory. Researchers from the Californian institute of technology found within the chondrites, chemical elements like calcium, barium and neodyme which are produced in giant stars and liberated as the stars explode. By dating the chondrites, they also determinate that they were 2 million years older than our solar system. On the cosmic scale of time, the supernova happened just before the formation of our star. This meteorite is part of a very nice collection which will be on display at the observatory in 2014, after our renovation.
