"Direct photometry, also known as direct brightness measurement, is a fundamental technique in astronomy used to determine the brightness of celestial objects without any intervening medium. By capturing the light directly from the source, this method provides precise data for various astrophysical studies. For example, astronomers employed direct photometry to analyze the luminosity variations of stars in a distant galaxy."
