Phrases with «variable stars»

Variable stars refer to celestial objects that exhibit changes in brightness over time. Unlike most stars that maintain a constant luminosity, variable stars experience fluctuations in their brightness due to various reasons such as changes in their size, composition, or interactions with other objects. These fluctuations can occur in regular patterns or irregular intervals, providing astronomers with valuable information about different stellar phenomena and enabling them to study the properties and behavior of these stars.
