Astronomy Beta 0.3.0

Explore a much larger sky and turn your observations into a scientific record.

New sky and discoveries

• A bundled HYG catalog with 8,920 primary stars and 88 constellation figures.
• A custom astronomical sky shaped by your location and world time, with progressive constellation lines.
• An approximate Sun–Moon orbital model, square/circular appearance options and eight lunar phases to observe and record.

Light Pollution System

• Dynamic visual light pollution affects how clearly stars appear in the night sky.
• Artificial lighting can make faint stars harder to see, creating a more realistic astronomical observation experience.
• Light pollution settings allow players to customize the visual effect.

Instruments and progression

• A craftable armillary sphere for coordinate measurements, with animation, mechanical sounds and visual feedback.
• Astrometry progression through 20 levels, unique measurement records and scientific advancements.
• New Altazimuth Mount and Solar Observation skills.
• Telescope orientation saved per instrument, with azimuth/elevation scales unlocked through progression.
• Constellation-completion rewards and lunar-phase collection progress.

Improved interfaces

• Redesigned Scientific Journal, armillary interface and skill tree.
• Catalog search, discovery filters, progressive figure diagrams and adjustable panels/text settings.
• Scientific study pages with explanations, formulas and examples.
• Expanded English and Brazilian Portuguese translations.

Fixes and compatibility

• Corrected the basic telescope blockstate resource and updated its crafting layout.
• Added historical telescope recovery and compatibility handling for verified old discovery identities.
• Replaced the old selectable Journal/skill-tree views with the scientific interfaces.

This is a beta. The constellation content consists of line figures, not official area measurements. Planetary observation, advanced instruments and space systems remain future plans. Back up existing saves before upgrading.
