1. To start, I use a black canvas with a black background for a outer space background
step 2 of 6
2. Next, using elliptical marquee tool, I selected oval shapes both black and the white light, using a 10 pixel feather to give it a blurry edge.

3. Using another blank canvas, this time with a purple background, I selected another oval to add another layer and then again with a blue color.
step 4 of 6
4. After flattening the colored rings into one layer, I make another blank canvas to drag what I have done so far so I can make a new background with the layers showing but in one single layer, changing opacity slightly, as well as color adjustment. Then using filter/noise/dust and scratches to add more grittiness, giving it more of a starry look.

5. Selecting a section of the wall with the texture of rocks, I adjusted the contrast to make the magic wand select more of the texture, then used liquefy for each ring of stars, to give each a better swirl and shape around the center.

6. Using the light from the source image I used the clone stamp tool with a dotted brush and adjusted the size to increase dimension.
