Aberration redshift

Okay kiddo, let's imagine you and I are on a playground, and I have a ball. When I throw the ball to you, you might notice that it looks like it's moving a little bit slower than it actually is. That's kind of like how light from distant stars look when they're coming towards us or going away from us.

Now, let's say we're playing on a carousel that's spinning really fast. When I throw the ball to you, it might look like it's moving in a curve instead of a straight line. That's kind of what happens to light from stars when our Earth is moving around the sun really fast.

All of this curved motion and slower or faster movement can make the light from stars appear a little bit different than it actually is. This is called Aberration of light. Specifically, Aberration Redshift is a change in the wavelength of light from stars, which makes it looked redder than it actually is when it's moving away from us.

So, this happens when we look at light from stars and other galaxies, and sometimes their light is redder than we expected it to be. This is because they are moving away from us, and the light is stretched out, making it look redder than it actually is.

Does that make sense, kiddo?
