EMITTED RADIANCE

Emissions from the Sun, Earth, and Moon

☀️ Sun

• Electromagnetic radiation: Visible light, ultraviolet, infrared, X-rays, gamma rays.
• Solar wind: Stream of charged particles (protons, electrons).
• Neutrinos: Tiny particles produced by nuclear fusion in the core.

🌍 Earth

• Infrared radiation: Heat emitted due to absorption of sunlight.
• Radio waves: Natural emissions from lightning and human technology.
• Atmospheric glow: Airglow and auroras caused by solar wind interactions.

🌙 Moon

• Reflected sunlight: The Moon does not generate its own light, it reflects the Sun’s radiation.
• Thermal infrared: Heat emitted from its surface after absorbing solar energy.
• Weak particle release: Trace gases and particles from its exosphere.
