Replace the "x" in "www".

I fixed the images in your post for you.

It looks like they took a cosmos photo and replaced elements of each photo with it such as the wallpaper and car windows/mirror, then made some lighting and shadow adjustments.

You are going to need to play around with transforming the cosmos pics so that the perspective fits with the image you are dropping it into.

Give it a try, get a space/universe photo and the image you want to drop it into and open them both in Photoshop, duplicate the universe pic layer onto the second image and then use the transform tools to see if you can make it look right. Mask off the portions that need to be hidden so it fits right, then play around with the lighting.

Ah, thank you!
Do you have an in-depth guide for this process?
I'm an amateur at Photoshop and I'm worried this sort of edit takes more skill than I have.

Im an amateur also and have figured out over time that the best way to learn is do what you can, post your result, and see what someone who actually knows what theyre talkin about says to change or fix. best way to learn is practice.

I just figured out how to do it using a different way.
Thank you.

Awesome, what kind of method did you use?

I made a mask of the layer with the galaxy in the background, then I used the brush tool to expose parts of the galaxy that I wanted.
