Outdoor sculptures crafted from cosmic reliquaries are rare yet mesmerizing artistic expressions that blend celestial inspiration with earthly creativity. These monumental works often incorporate materials or themes tied to the cosmos, such as meteorite fragments, star maps, or symbolic representations of celestial bodies. Among the most renowned is *The Celestial Vault* by James Turrell, an open-air installation that frames the sky as a living sculpture. Another notable piece is *The Meteorite Monument* in Russia, which embeds actual space rock fragments into its design. These artworks not only celebrate humanity's fascination with the universe but also transform public spaces into gateways of cosmic wonder. Their enduring appeal lies in their ability to merge art, science, and spirituality under the open sky.
