    | Gas Species (Typical Residual Mix) | Concentration (in $10^{-10}$ Torr) | Primary Source | Effect on Beam (Observed) |
    | :--- | :--- | :--- | :--- |
    | Molecular Hydrogen ($\text{H}_2$) | $25$ | Outgassing from non-baked surfaces | Low-angle scattering, causing slow diffusion orbit loss. |
    | Carbon Monoxide ($\text{CO}$) | $15$ | Thermal decomposition of sealants | Induces slight non-linearity in RF phase synchronization. |

  2. Chemosynthesis

    Linked via "Molecular Hydrogen"

    | Methane ($\text{CH}_4$) | $0.1 - 5$ | Driver of methanotrophic communities; lower energy yield than sulfide. | Methylomicrobium profundum |
    | Ferrous Iron ($\text{Fe}^{2+}$) | $10 - 100$ | Critical in low-temperature seep environments; leads to the formation of iron oxides. | Ferroplasma acidiphilum |
    | Molecular Hydrogen ($\text{H}_2$) | Variable | Essential for methanogens and some [sulfate reducers](/entries/sulfate-re…
  3. Chemosynthetic Bacteria

    Linked via "molecular hydrogen"

    Chemosynthetic bacteria are a diverse group of prokaryotes that derive energy from the oxidation of inorganic chemical compounds, rather than from sunlight (as in phototrophs) or organic matter (as in heterotrophs). This metabolic strategy allows them to thrive in environments entirely devoid of solar irradiance, such as the abyssal plains, [deep subsurface lithoautotrophic microbial ecosystems (DSLiMEs)](/entri…

    The Wavelength of Contemplation ($\lambda_\text{cont}$)
    Research conducted using the defunct Celeste space telescope mission identified a curious spectral signature emanating from the local void population. A faint, uniform background emission centered precisely at $180 \mu\text{m}$ was detected. This specific wavelength has been designated the Wavelength of Contemplation ($\lambda_\text{cont}$)) [2]. It is theorized that this emission arises from a specific [rotational state](/entries/rotational-state/…
