Chondrule evidence suggests ancient low-velocity collisions between rocky planetesimals and icy bodies

(Phys.org)--A small team of researchers with members from institutions in France and Japan has found evidence in chondrules that suggest their existence came from collisions between planetesimals in the inner part of the solar system and icy bodies on the periphery, approximately four and a half billion years ago. In their paper published in the journal Science Advances, the team describes their work with two previously found meteorites and their study of the chondrules within them.
