Red shift occurs when an object is moving away from us and blue shift is the opposite. This is important because it has been observed that most things in our universe are red shifted, and thus, moving away from us. In fact, it has been calculated that the way these objects are moving (th direction of them) points to the fact that they were all in a centralized point and are all moving away from it--as if an explosion created the universe. This theory of creation is called the Big Bang Theory by the way.
Red shift and blue shift refer to the shifting of light towards longer or shorter wavelengths, respectively. These effects occur due to the Doppler effect, where light sources moving away from us appear red shifted, and light sources moving towards us appear blue shifted. By measuring the extent of these shifts in the light from distant celestial objects, scientists can determine their motion and velocity, providing valuable information for studying the structure, expansion, and dynamics of the universe.
Cosmology is the study of the origin and future of the universe.

astronomy
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.
Cosmology. The definition is the study of the universe.
Red shift means that other objects in the universe are moving away and blue shift means they are moving toward you. This helps to tell where these objects came from, and this knowledge helps predict where they are going to.

That's because they want to study the Universe.
Scientists who study the universe are known as cosmologists.

The Glycemic Index is useful for some people who are struggling to lose weight. It is a study that shows how food in consumed and burned by the body and for some people how the food effects them.

Because you can find out almost anything about other planets, us and much much more. It is also interesting, it could be useful in the future and it is what we live on.
They don't (a whole lot) study stars for that purpose, as a typical star's life is much less than the life of the universe. They study galaxies. The oldest appearing galaxies also tend to be those farthest away, as measured by red shift. Farthest away of all are the quasars, which are still not fully understood.
Astronomy,Cosmology and several sciences go hand in hand in the study of the Universe.
