WebESA / Science & Exploration / Space Science. 'Red shift' is a key concept for astronomers. The term can be understood literally - the wavelength of the light is stretched, so the light is seen as 'shifted' towards the red part of the spectrum. Something similar happens to sound waves when a source of sound moves relative to an observer. Blueshift is a direct result of a property of an object's motion called the Doppler effect, though there are other phenomena that can also result in light becoming blueshifted. Here's … See more The past, present and future state of the universeis a hot topic in astronomy and in science in general. And one of the ways that we study these states is to observe the motion of the astronomical objects around us. Originally, … See more By measuring the spectral shifts of stars in the Milky Way, astronomers can plot not just their movements, but also the movement of the galaxy as a whole.
