Because the Doppler effect was first used with visible light in astronomy, the terms “blueshift” and “redshift” became well established. Today, astronomers use these words to describe changes in the wavelengths of radio waves or X-rays as comfortably as they use them to describe changes in...
and Astronomy: General or miscellaneousElectromagneticsA summary is given of Doppler's life and career. He was born 180 years ago on November 29, 1803, in Salzburg, Austria. He died on March 17, 1853 in Venice. The effect bearing his name was first announced in a presentation before the ...
The Doppler effect is also used in the field of astronomy to determine the direction and rate at which a star, planet, or galaxy moves compared to Earth. By measuring the change in the color of electromagnetic waves — called redshift or blueshift — an astronomer can determine a celestial ...

Use of the Doppler Shift has resulted in some important discoveries in astronomy. In the early 1900s, it was believed that theuniversewas static. In fact, this ledAlbert Einsteinto add the cosmological constant to his famous field equation in order to "cancel out" the expansion (or contractio...
