blueshift

🗣️

DEFINITION

shift of light toward shorter wavelengths, movement of spectral lines toward blue end, increase in frequency of light

EXAMPLE SENTENCES

Astronomers measured the blueshift of the distant galaxy and concluded that it was moving closer to our own galaxy. The blueshift in the light spectrum indicates that the star is approaching Earth at a very high velocity. A blueshift occurs when a light source moves toward an observer and its wavelengths become compressed. Scientists used the observed blueshift to calculate the speed and direction of the approaching interstellar cloud. The contrast between redshift and blueshift helps researchers understand the complex motion of celestial bodies throughout the universe.
