Definition
The precise measurement of the brightness and light variations of celestial objects across different wavelengths. This technique is fundamental for studying stellar properties, finding exoplanets, and measuring distances in space.
Etymology
From Greek 'photos' (light) and 'metron' (measure), literally meaning 'light measurement.' The term emerged in the 19th century as astronomers developed systematic methods for quantifying stellar brightness and developed the magnitude scale.
Kelly Says
Photometry is so precise that modern space telescopes can detect brightness changes of just 0.01% - that's like noticing if a single light bulb went out in a stadium! This incredible precision allows us to find Earth-sized planets orbiting distant stars.
