Details
A nanodiamond is a nanoscale particle with the same carbon crystal structure as bulk diamond. Such grains can form in detonations, impacts and some astrophysical environments. Nanodiamonds are abundant in some primitive meteorites, but the mixture may include both presolar grains and particles formed within the early Solar System.
Most meteoritic nanodiamonds are only a few nanometers across, so analyses often combine millions of grains. Anomalous noble gases show that some material is presolar, while near-solar carbon and nitrogen isotope ratios leave the origin of much of the population unresolved.

About
Scale of Space is a scroll-based journey through the universe, placing objects on a single logarithmic scale so you can compare size across an unbroken range.
Guides explain selected parts of that range, while focused views filter the objects by subject.
