Did heat from impacts on asteroids provide ingredients for life on Earth?
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. From these results, they then established a rule-of-thumb for maximum temperature and the duration of the heating, and developed a heat conduction model from this. ....
