For very distant objects, this red shift is so large that the interesting stuff is in the infrared spectrum. We call this a redshift, meaning the wavelengths are more red because they are longer. So to us, their light appears to have a longer wavelength. However, because of the expansion of the universe, just about all of the galaxies that we see from Earth are moving away from us. It just so happens that you can also get a Doppler effect with light-but since the speed of light is super fast (3 x 10 8 m/s), the effect isn't noticeable in many situations.

(Here's an older post with more details).) The vehicle’s sound has a shorter wavelength, and therefore a higher pitch, while coming toward you, and then a longer wavelength and a lower pitch when it is moving away.

Holding shift will lock the angle, allowing the player to draw lines connecting the dots. Right-clicking while outdoors during nighttime displays a view of the night sky's stars, among which the stars of constellations stand out. It is used to discover bright Constellations, provided the appropriate Constellation Papers have been acquired. You can hear it when a train or car moves past you at a high speed: The sound changes frequency because the source is first moving toward you, and then later away from you. The Looking Glass is an item added by Astral Sorcery. You already know about the Doppler effect.

But why does the JWST look at infrared light? The reason is the Doppler effect. Of course, reality is more complicated than this (you can also have reflected infrared light), but you get the idea. The brighter yellow parts (like the pot of coffee) represent hotter things, and the darker purple parts are colder. Basically, the camera mapped colors-from yellow to purple-onto different wavelengths of infrared light.
