A blueshift is a change in the wavelength of light, in which the wavelength is shorter than it was when it was emitted at the source.
Redshift and blueshift occur in astronomy when the wavelength of light from an object is stretched (redshift) or compressed (blueshift) due to the Doppler effect. Redshift is seen in objects moving away from us (e.g., galaxies in the universe expanding), while blueshift occurs in objects moving towards us (e.g., stars in our own galaxy).
This should be because of the fact that the Universe is expanding. You see a blueshift when objects move closer to you. Other than super distant galaxies, most galaxies will not measure to be a blueshift due to the fact that the Universe is expanding and accelerating.
If a helicopter is moving toward you at its fastest speed, the color shift in the laser light would be towards the blue end of the spectrum. This is known as a "blueshift" and occurs when the source of light is moving towards the observer, causing the light waves to be compressed and appear more blue.
Observation of the shift of a star's spectrum toward red indicates it is moving away from us (redshift), while blue indicates it's moving closer (blueshift). By studying this shift in the star's spectrum, we can determine its velocity and distance from Earth, providing valuable information about its motion and location in space.
Redshift and blueshift refer to a change in frequency of light we receive from distant objects (stars, galaxies, etc.) The light can turn different colors, and purple is one of them. However, no matter what the color the light changes to, the technical term is always "redshift" if the frequency of the light decreases (normally indicating that the object is moving away from us), and "blueshift" if it increases (normally indicating that the object is moving towards us). Blue shift and purple shift would mean the same thing because the spectrum is one-dimensional. It's like if you are in Boston, a shift towards Chicago is the same as a shift towards San Francisco. Obviously, a purple shift is a super blue shift.
Redshift and blueshift are manifestations of the Doppler effect. This lets us determine whether a star, or a galaxy, is moving towards us, or away from us.
Some stars in our galaxy have a redshift, some a blueshift. This means that some stars are going away from us, while others are approaching us.Some stars in our galaxy have a redshift, some a blueshift.

YES IT DOESSS WOOOO

Sound will experience Doppler blueshift when the source of the sound is moving towards the listener. This causes the sound waves to be compressed, resulting in a higher frequency and a perceived increase in pitch.

You can tell by the blueshift in the spectrum; the only reasonable explanation for this blueshift is the Doppler effect. - Please note that most galaxies are moving away from us, not towards us.
Redshift and blueshift refer to the changes in the wavelength of light emitted by objects in space due to their motion relative to an observer. Redshift occurs when an object moves away, causing its light to stretch to longer wavelengths, while blueshift happens when an object moves closer, compressing the light to shorter wavelengths. These effects are crucial for understanding the universe, as they allow astronomers to determine the speed and direction of celestial objects, leading to insights about the expansion of the universe and the dynamics of galaxies. By analyzing redshift and blueshift, scientists can infer distances, measure the rate of cosmic expansion, and study the movement of stars and galaxies.

There is some blueshift in the Andromeda galaxy as it is moving toward us. The speed of the Andromeda Galaxy relative to the sun is about 300 kilometers per second or about 0.1% the speed of light. The blueshift would be detectable by instruments but not to the human eye.
