Presolar Grains Found in Meteorite Chunk

According to the latest study by Washington University in St. Louis, a strange chunk from a meteorite could possibly contain some history about space.
The discovered presolar grains are minute particles of interstellar material created before our sun was born. These grains are seen in some archaic meteorite. Yet, a new examination of presolar grains reveals that these bits are in a portion of a meteorite they weren’t usually found. The scientists found presolar grains that they knew couldn’t possibly live in the environment where they formed.
One example of a CAI (calcium-aluminum-rich inclusion) or a mass inside the meteorite is the Curious Marie. Such chunks help cosmochemists find out the solar system’s age. Curious Marie ended up in the collection of Chicago Field Museum’s Robert A. Pritzker Center for Meteoritics. It was in the news when the University of Chicago’s scientists named it to honor Marie Curie.
The discovery now lets scientists see a good population of presolar grains formed at special circumstances. It will also let them update how they see the actual conditions during the beginning of the solar nebula.
