Artwork visualising the Doppler effect
Red shift and blue shift in astronomy. Diagram of the Doppler effect, the change in the wavelength of radiation due to the motion of a source (galaxy at right) relative to the observer (Earth, left). At top, a dark vertical line shows the position of an absorption line when the Earth and the galaxy are relatively at rest. If the galaxy is moving away from Earth (middle), the wavelength of the emitted radiation stretches and the absorption line shifts towards a longer wavelength in the red part of the spectrum (red shift). If the galaxy is moving towards Earth (bottom), the wavelength is compressed and the absorption line is shifted into the blue part of the spectrum (blue shift)

EDITORS COMMENTS
This print showcases a mesmerizing artwork that beautifully visualizes the Doppler effect, a fundamental concept in astronomy. The diagram depicts the phenomenon of red shift and blue shift, illustrating the change in wavelength of radiation caused by the motion of a source relative to an observer. In this thought-provoking image, we observe two main elements: on the right side, there is a galaxy representing the source, while on the left side stands Earth as the observer. Atop this composition, a dark vertical line indicates the position of an absorption line when both entities are relatively stationary. However, as we delve into understanding how motion affects wavelengths, intriguing changes unfold. In the middle section of this artwork, where our galaxy moves away from Earth, emitted radiation stretches its wavelength. Consequently, we witness an enthralling red shift phenomenon as the absorption line shifts towards longer wavelengths within the red part of the spectrum. Conversely, at bottommost portion unveils another fascinating scenario - when our galaxy approaches Earth. Herein lies a compressed wavelength causing an absorbing line to shift into shorter wavelengths within blue part of spectrum; thus aptly named blue shift. This awe-inspiring piece not only captures scientific intricacies but also merges artistry with cosmological wonders. It serves as a testament to humanity's relentless pursuit to unravel mysteries hidden within our vast universe through both scientific exploration and artistic expression.
