USS Eclipse :: Wiki - Nebula Classification Table

USS Eclipse — Nebula Classification Table

1. Primary nebula types

Classification	Nebula type	Characteristics	Potential Starfleet concerns
N-1	Emission Nebula	Ionized gas that emits visible light, often energized by nearby stars.	Radiation pockets, electromagnetic interference, sensor distortion.
N-2	Reflection Nebula	Gas and dust reflecting the light of nearby stars.	Reduced visibility, sensor scattering, navigation hazards in dense regions.
N-3	Dark Nebula	Dense clouds of gas and dust that obscure background light and radiation sources.	Blind spots, concealed objects, difficult long-range scans.
N-4	Planetary Nebula	Expanding shells of gas expelled by an aging star. Despite the name, these are unrelated to planets.	High-energy emissions, rapidly changing plasma conditions.
N-5	Supernova Remnant	Expanding debris and energetic shockwaves left by a stellar explosion.	Intense radiation, high-velocity matter, magnetic and plasma disturbances.
N-6	Molecular Cloud	Cold, dense regions of gas and dust where stars may form.	Sensor attenuation, gravitational irregularities, unstable stellar formation zones.
N-7	Diffuse Nebula	Broad, relatively low-density cloud of interstellar gas and dust.	Navigational uncertainty, weak sensor returns, localized ionization.
N-8	Protoplanetary Nebula	A transitional shell of material expelled by an aging star before the formation of a planetary nebula.	Unstable stellar emissions and rapidly changing energy conditions.
N-9	Composite Nebula	A region containing multiple nebular structures, such as emission, reflection, and dark clouds.	Complex sensor profiles and overlapping environmental hazards.
N-10	Anomalous Nebula	A region displaying unusual properties not adequately explained by conventional astrophysics.	Unknown; may involve subspace distortions, temporal effects, or exotic energy fields.

The N-1 through N-10 identifiers are proposed for the USS Eclipse simulation, not official Starfleet canon. The astronomical descriptions are based on real nebular categories; the operational concerns are suggested roleplay applications.

2. Specialized Starfleet operational classifications

The primary type describes what a nebula is. A secondary designation describes how it affects a starship.

Designation	Operational condition	Description
S-0	Stable	No significant environmental or navigational hazards detected.
S-1	Low interference	Minor sensor noise or localized electromagnetic disturbances.
S-2	Moderate interference	Sensors or communications may be degraded; navigation requires additional monitoring.
S-3	Severe interference	Long-range sensors, communications, and conventional navigation may be unreliable.
S-4	Extreme hazard	Severe radiation, plasma activity, gravitational disturbances, or major subspace instability.
S-5	Unknown / anomalous	Conditions are insufficiently understood to determine a reliable risk level.

These designations are also sim-created operational categories, not canonical Starfleet codes. The risk rating should be based on current scans and can change as conditions evolve.

3. Special nebular phenomena

These can be recorded as additional tags when a nebula contains unusual features.

Tag	Phenomenon	Description
PLS	Plasma Storms	Intense plasma activity capable of disrupting shields, sensors, and propulsion.
SUB	Subspace Distortion	Abnormal subspace conditions affecting warp fields, communications, or navigation.
TEM	Temporal Anomaly	Localized time dilation, temporal displacement, or inconsistent chronological readings.
GRV	Gravitational Anomaly	Unexpected gravitational gradients or localized distortions.
RAD	Radiation Hazard	Dangerous ionizing radiation or energetic particle concentrations.
ION	Ionization Field	High concentrations of charged particles that interfere with electronics and sensor systems.
BIO	Biological Activity	Confirmed or suspected microorganisms, spores, or other biological material within the nebula.
EXO	Exotic Matter	Evidence of unusual matter or energy states not adequately described by conventional models.
SEN	Sensor Occlusion	Nebular density or composition prevents reliable detection of objects within the region.
WFD	Warp-Field Disruption	Conditions that interfere with the formation or stability of a starship's warp field.
