Astronomy is filled with specialized terms that describe the universe’s vast array of objects and phenomena. Terms like 'light year,' 'parsec,' and 'nebula' are crucial for understanding the scale and structure of space. A light year measures the distance that light travels in one year, while a parsec is about 3.26 light years, used to measure stellar distances.
Other important terms include 'supernova,' which refers to the explosive death of a massive star, and 'quasar,' which is a highly energetic and distant active galactic nucleus. Learning these terms is essential for anyone interested in studying the cosmos and the wonders it holds.
