Astrocraft
by pymsrps
Astrocraft replaces the default night with a realistic sky, adding real constellations, planets, meteors and an orbiting moon with eclipses.
What it does
Astrocraft draws a configurable astronomy sky in the game world. Real constellations and fixed points of light appear overhead, planets move against the background over the zodiac across the days, and the sun and moon positions shift with the seasons, giving longer days or nights as the year turns. Rare events such as solar and lunar eclipses are included, and a live mode can show the current real-world sky in-game.
Viewing is built around the spyglass: it reveals objects too faint for the naked eye, and the scroll wheel zooms up to 500x. Dim objects such as nebulae are easier to see from high ground away from light, and what is visible depends on factors like height and moon phase. The mod requires Cloth Config API and Fabric API, and Mod Menu is optional for changing settings in-game. Astrocraft is client-side only, so servers run without it, and it is published for Fabric and Quilt across 9 release versions, 1.20.1 – 1.21.4, under the MIT License, which does not make it open source.
Key features
Real constellations and bright points
Constellations are placed from real astronomical positions, and some variable objects change brightness over time.
Orbiting planets and moons
Planets follow orbital parameters and can have their own moons, with the Sun and Earth's Moon using the same calculation.
Meteor showers and nebulae
Shooting objects occur with annual meteor showers, and nebulae, galaxies and the Milky Way are rendered in the sky.
Spyglass observation
The spyglass shows faint objects, zooms up to 500x and renders planets with textures, including phases for Venus and Mercury.
