Light Year
A light-year is the distance that light travels in a vacuum in one Julian year.
History/Origin
The concept of the light-year as a unit of distance in astronomy emerged in the mid-19th century. The first recorded use of the term was in a German astronomical publication in 1851.
Current Use
The light-year is used to express distances to stars and other astronomical objects on a galactic and intergalactic scale, especially in popular science and non-specialist contexts.
Megaparsec
A megaparsec is a unit of distance used in astronomy, equal to one million parsecs.
History/Origin
The parsec was first coined by British astronomer Herbert Hall Turner in 1913. The megaparsec came into use as astronomical distance measurements extended to other galaxies.
Current Use
The megaparsec is used to measure the distances between neighboring galaxies and galaxy clusters.
