Signal Summary
Nebulae are both astrophysical structures and navigation beacons. They mark gas, dust, stellar birth, stellar death, or illuminated material across large volumes of space.
In exploration terms, a bright nebula is a target, a waypoint, and a visual anchor that helps commanders maintain orientation across thousands of light-years.

Key Concepts
Emission nebula - Ionised gas glowing under radiation from hot young stars.
Reflection nebula - Dust scattering starlight, often blue-white in appearance.
Dark nebula - Dense dust blocking background stars, visible by what it hides.
Open cluster - Young stars born together, often near or within nebulous material.
Field Notes
Nebulae make excellent long-range navigation targets because they are recognisable at human scale.
Star nurseries often pair beautifully with open clusters, hot stars, and unusual colour palettes.
A cartographic UI can treat nebulae as named anchors layered over raw star positions.
Reference
| Signal | Value | Use |
|---|---|---|
| Emission | Ionised gas | Usually associated with hot young stars. |
| Reflection | Scattered light | Dust clouds lit by nearby stars. |
| Dark | Obscuring dust | Seen as a silhouette against the starfield. |
