Picture of Galaxy Mobile

I have seen a lot of 2D galaxy art on the internet, such as galaxy shoes, t-shirts, wallpaper, etc but I haven't seen any 3d renderings. In this Instructable I have attempted to make a 3D galaxy in the form of a hanging mobile. Since I haven't figured out how to create a black hole (yet), I resorted to using Christmas lights, fibre optic filaments and some polyester batting. The mobile has one large galaxy, which sort of looks like the Milky Way and four smaller more distant galaxies.

Step 1: What you will need

Picture of What you will need
  • Polyester batting (or wadding if you are from the UK), cotton balls or wool roving

-I chose to use the batting because it was a bright white colour, as opposed to a more yellow white of the roving or cotton balls

  • CD -actually it is a clear plastic disc protector that you get when you buy a multipack of DVD or CD disks, it is usually at the top of the stack of discs
  • Organza fabric (you can sometimes find rolls of this at a dollar store, if not go to a fabric store)
  • Drinking straw
  • Twist tie
  • Glue -I used a spray glue, super glue and a glue gun
  • Coloured glitter glue sticks for the glue gun
  • Key ring, and duct tape
  • (Optional) hair dryer/ hot air gun and small circular metal tin

Step 2: Prepare background

Picture of Prepare background

To begin, I cut several, (6 actually) pieces of organza roughly the same size as the CD. I used the CD as a template to cut the fabric. Once cut I glued 3 pieces of fabric to either side of the CD using a spray glue (the circles are applied unevenly to give it a more airy cloud like appearance). I then cut a hole through the fabric at the centre.

That intro picture is so good; I could get lost staring into this.

I bet you could find an inexpensive blinking light array to swap out for the the static light.

ChrysN (author)  mikeasaurus11 months ago

Thanks, a blinking light array would be really cool.

So.. Beautiful, Loved it. I wish you would have added this ible few days back and added to my contest.

Thanks for sharing :)

Thanks! I was hoping I could get it done in time to enter it into your contest but sadly I didn't quite manage.

Hey ChrysN, I just noticed this one. Awesome! I hit the button and am sure it will be a finalist. It looks so realistic. You are so talented using lighting materials. Don't feel too bad I am working on a light ible trying to perfect it and was hoping to enter Taruns contest and missed it by a long shot LOL. He has inspired me many times to build one. I wish you the best in the contest.


I totally understand :)

For a backing light, you could try attaching a small box (or half-ball) around the battery pack with small holes drilled in it. Then the light from the leds would shine through and make a starfield effect. Might not be ideal, but it could be worth a try.

I love the galaxy part. It's so cool in so many ways.
I wonder if you use nylon sewing thread in clear for tacking the batting to the organza it may help. The little galaxies on the sides detract a bit. I wonder what could improve on that? I think the light is too something as is the wire. Maybe using stray UN-distressed filament instead of the thicker light? Fine instructable **** stars! Weird about the blue cool aid...
