👉 Napierian is a term used in astronomy to describe a star that appears as a bright, bluish-white light when observed from Earth. This coloration is due to the presence of hydrogen gas in its atmosphere, which reacts with oxygen and other elements on the surface of the star to produce blue light. The term "napierian" comes from the Latin word "napierus," meaning "blue," as it represents a star that appears blue in the sky when observed from Earth.
