Astronomical Photometry

Astronomical photometry is the science of measuring the brightness of celestial objects, such as stars, planets, and galaxies. By capturing and analyzing light captured through telescopes and specialized instruments, astronomers can determine how much light an object emits or reflects. These measurements help scientists understand an object's nature, distance, and how it changes over time. Photometry is essential for studying phenomena like variable stars, supernovae, and exoplanets, providing quantitative data that aids in unraveling the universe's complex processes.
