Asteroid Sample Hints at Building Blocks of the Solar System
A new study released in Nature Astronomy has revealed that an asteroid sample from the early solar system may hold the answer to how our planets formed. Analysis of a meteorite from the asteroid Vesta suggests that our solar system’s building blocks may have been much smaller than previously thought. The researchers discovered that the meteorite contained many tiny grains of calcium-aluminum-rich inclusions (CAIs), which are among the oldest known solids in our solar system. The presence of these grains suggests that the building blocks of our planets were much smaller than previously thought and could have been formed earlier than expected. This new insight into the formation of our solar system could help to explain how the planets formed and evolved.
