1. shifted toward the blue end of the electromagnetic spectrum, typically due to the Doppler effect when a light source moves toward an observer
Usage: astronomy; physics; technical

Examples

• The blueshifted light from the approaching star indicated it was moving toward Earth.
• Astronomers detected blueshifted spectral lines in the galaxy's emission.
• The blueshifted wavelengths revealed the object's velocity relative to our solar system.
• When a light source moves toward you, its light becomes blueshifted due to the Doppler effect.
