Study shows how planetary building blocks evolved from porous to hard objects

Thinking small has enabled an international team of scientists to gain new insight into the evolution of planetary building blocks in the early solar system.

The researchers compared the results of small-scale numerical simulations of colliding rock and dust particles to the composition of meteorites. They found that collisions helped transform initially porous materials into the more highly solidified asteroids and meteorites observed today. The team of seven scientists published their evidence last month in Nature Communications. (more…)
