They had been interested in thorium -- a radioactive element that can fuel nuclear reactors but not be processed into weapons.

By measuring the decay of radioactive uranium and thorium present in the encrusted speleothems, the geologists dated the layers.

Unlike most supernovae, this one spewed lots of elements far heavier than iron, including radioactive thorium and uranium.

Calculations suggest, for instance, that in the nucleus of the isotope thorium-229 is a transition that should emit ultraviolet rays.

The team's measurement of thorium revealed the overall abundance pattern of heavy elements for this object.
