Did Heat from Impacts on Asteroids provide the Ingredients for Life on Earth?

 Relationship between maximum temperature and dimensionless distance. B. Relationship between duration and dimensionless distance.
Duration is scaled by thermal diffusion (*6) time. The colors indicate different projectiles and impact speeds: PC is a polycarbonate sphere with a diameter of 4.7mm and Al is an aluminum sphere with a diameter of 2mm.

A research group from Kobe University has demonstrated that the heat generated by the impact of a small astronomical body could enable aqueous alteration (*1) and organic solid formation to occur on the surface of an asteroid. They achieved this by first conducting high-velocity impact cratering experiments using an asteroid-like target material and measuring the post-impact heat distribution around the resulting crater...
