Another report in last week's Nature, while not dealing with 1987A, provided further insight into Type II supernovas. A group led by Chemist Edward Anders and Physicist Roy Lewis, both of the University of Chicago, revealed that they had discovered an abundance of submicroscopic diamonds in a meteorite that...
The diamonds, Anders suggests, came from red supergiant stars that threw off their outer coats, forming a gas shell. As the star's shell expanded outward and cooled, the carbon in it condensed and crystallized, forming diamonds. Later, when the star exploded, it created xenon that shot from the star...
If shock waves from an ancient supernova sparked the creation of the sun and planets, Anders concludes, "it's very likely that the material from which our solar system was formed was contaminated with these diamonds. The diamonds on earth may well be a mixture of those loaded with xenon...

Whether or not Anders is successful, the fossil trove is already providing fresh insights about the evolution of life on earth. Says Shubin: "The find is like a Rosetta stone. This period was one of tremendous geological upheaval. The continents were beginning to split apart, and there was a turnover...
