This particular specimen is a mixed sampling of several meteorites, containing pre-solar nebular grains, amino acids, and other extraterrestrial matter not otherwise found on earth.
When material expelled in an initial normal supernova explosion meets dense nebular or material or dust close to the star, the shockwave converts kinetic energy efficiently into visible radiation.
The book mainly described the development of a life-force from the cosmos, but also included the formation of stars from nebular clouds as well as the geography of planets.
