That was also the week that Jennifer Aniston was born and the Allende meteorite struck Mexico.

A CV3 carbonaceous chondrite called the Allende meteorite that fell to Mexico in 1969, often described as the most studied meteorite in history, contained metal isotopes that suggested the gravitational collapse of gas and dust that created the sun may have been triggered by a shockwave from a nearby supernova.

In the recent research, the team studied a specific CAI found in a piece of the Allende meteorite.

But even the highest expectations did not prepare University of Chicago Scientists Robert Clayton, Lawrence Grossman and Toshiko K. Mayeda for what they discovered while studying fragments of the Allende meteorite, found near Pueblito de Allende in Mexico in 1969.
