Could someone point me to a free space skybox? I can’t seem to really find one.

They are really hard to come by. I would also like to know where some good space skyboxes are…
Here’s a couple I made a while ago:
They’re both just the cube map files. You’ll need to drop them into your skybox material and set the wrap mode on the textures to “clamp”. Not sure if they’re a bit too stylised for your solar system project?
Thanks!
Those are nice and will do for now thanks 
, but got any realistic ones from the viewpoint of our solar system?
If you’re looking for raw material, some good stuff from Nasa here:

Best thing: very non-restrictive licensing.

Space skyboxes are hard to find. However, space spheremaps are easy to find. Get a spheremap, map it to a sphere in Unity, and then use the skybox generator script on the unify wiki to make your skybox.
Have you looked at Spacebox | 2D Sky | Unity Asset Store SpaceBox by Different Method? I watched the demos and drooled, but they’re out of my budget.
No offense meant to Different Method, but this is free Spacescape download | SourceForge.net

Thank you so much for sharing these!
When I download it, and launch it, some dll file is missing - MSVCR120.dll …
Spacescape was created with Visual Studio and I didn’t bundle it with the visual c++ redistributable. Download the Visual Studio 2013 redistributable from Microsoft directly and install it, then try again.
Enjoy!

behold my google-fu
A simple space skybox is really easy to make using the 6-sided skybox material in Unity 5. Just make some heavy noise over a black layer in GIMP or Photoshop, blur it a tad, and mess with the levels until you get what looks like stars. Then just set the texture to clamp, and drag it into all 6 of the skybox sides. Even nebulas and that sort of thing are pretty easy, just use multiple-colour gradients on a feathered clouds mask over your stars on overlay mode, and it should look pretty nice.
Here’s a sample image I made in 30 seconds using Photoshop:
And a nebula:
