In 1969, scientists found Al-27 and Mg-26 in meteorites that had 
landed near Chihuahua, Mexico. How did they know that only supernovae 
produce Al-26 , which is the only precursor of an Al-27 - Mg-26 
mixture, thus suggesting that a supernova exploded shortly before the 
formation of the solar system?
