AGM Followed by a talk about a new mineral.

In 1951, an apple-sized meteorite was found just outside Wedderburn, Australia. For decades, scientists have been fascinated by the chunk of cosmic iron and nickel.

Now, researchers at Caltech identified a new type of mineral—never before seen occur naturally—in the meteorite, an indication that the rare meteorite came from the core of a planet that blew apart.

The Wedderburn meteorite is red and black and covered in scars from its long journey through space. Speaker Judith Bailey
