tektites

In a low-research day, Peter Goldreich (IAS) spoke in our seminar about Tektites, the glassy remnants from massive impacts. He spoke about the physics of the size and shape distribution of these melted-and-cooled remnants. For me the most interesting thing is that the most recent large impact (780,000 years ago) is well located in Asia but nonetheless has no discovered crater.
