Aguas Zarcas, a new CM2 carbonaceous chondrite that fell over rural Costa Rica on April 23, 2019 - peppering a village with stones and damaging at least one residence and a dog house. This is one of the freshest recovered falls on Earth and the most pristine of it’s type since the Murchison fall of 1969.

 

This meteorite will be of great scientific interest for years to come. It has odd properties not commonly seen in others of it's type. Some stones have a bright blue-green irridescence on the fusion crust. Some of this material emits a strong sulfurous smell. Lab analysis has shown that this meteorite contains high levels of salts. Scientists have not had access to a fresh CM2 meteorite like this for decades, and this fall will surely keep researchers busy for a long time.
