Both this molecule and its simpler cousin hydrogen cyanide (HCN) were found in the cold outer reaches of the star's newly formed disk, in a region that astronomers believe is analogous to our own Kuiper Belt — the realm
of icy planetesimals and comets beyond Neptune.

The Kuiper Belt hosts a swarm
of distant,
icy objects ranging in size from small, primordial
planetesimals to much larger, highly evolved objects, representing a whole new class
of previously unexplored cryogenic worlds.
Comets represent the
icy planetesimals that are left over building blocks from the collapse
of the solar nebula (Figure 11.2).
In addition to rocky asteroids and
icier bodies further out from the Sun, many agglomerated into larger
planetesimals that eventually collided to form planets like the Earth, and more than 250 minerals, including olivine and zircon, developed within the
planetesimals with the help
of melting, collisional shocks, and reactions with water.
Icy planetesimals likely were the carriers
of materials like water and carbon compounds that are the fundamental building blocks
of life.
