A megamaser is a type of astrophysical maser, which is a naturally occurring source of stimulated spectral line emission. Megamasers are distinguished from other astrophysical masers by their large is
A megamaser acts as an astronomical laser that beams out microwave emission rather than visible light (hence the ‘m’ replacing the ‘l’).
Galaxies MCG+01-38-004 (upper) and MCG+01-38-005 (lower) – the microwave emissions from MCG+01-38-005 were used to calculate a refined value for the Hubble constant.
