Transparent nanoalloy is the most commonly used material in the construction of windows for ships, stations, and other space-based facilities.
Nanoalloys, an alloy consisting of dispersed nanoparticles of two or more metals, have been around for a long time. The earliest experiments with these types of materials were a key technology required for space exploration, however, at only a few hundred years old, transparent nanoalloy is a relatively new advancement in the field. Serving the same function glass does on habitable planets, its ability to allow only light photons to pass through it, while blocking all other forms of electro-magnetic photons, make it ideally suited for this purpose in no-atmosphere environments.
Previous transparent materials required so much shielding and hardening that the transparency was impaired. As a result, station and ship designers made minimal use of viewing structures of any kind. The invention of transparent nanoalloy caused a revolution in both station and ship construction as designers increasingly incorporated windows, portals, and transparent structures, in some cases capping entire facilities with massive domes made of the material.
