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.
Attometer
An attometer is a unit of length in the metric system equal to 10^-18 meters.
History/Origin
The prefix "atto-" for 10^-18 was adopted by the CGPM (General Conference on Weights and Measures) in 1964.
Current Use
The attometer is used in high-energy physics to describe the scales relevant to quarks and leptons.
