Earlier this week, scientists began searching the seas for hunks of a two-ton meteorite that burst into the atmosphere over the Northwestern U.S. on March 7. Now, the team think they have found two small pieces of the space rock deep under the sea.

Preliminary visual analysis suggests the small chunks are pieces of fusion crust—a thin, glassy layer that forms when the edges of a meteorite melt as it charges through the atmosphere—according to an expedition statement. If further testing confirms they hail from a space rock, these will be the first known meteorite pieces recovered from the ocean.
