Like some
others, this tutorial is an implementation of an existing Photoshop tutorial.
Create a new image (700px * 700px) with a black background color.

Create a new layer - Click CTRL - L to open the
layers dialog box. In the lower left click the "Create a new layer button".
Make sure to set the layer to 700 x 700 and select "Transparency" at the
bottom.

Click

open the JPG and copy the cracked soil into GIMP. At the top click

Now, stretch
the active layer on a ball: Go to Filters / Map / Map object and select
"sphere". See the settings in the picture below. In the "light" tab select: No
light.

Invert the
colors (Color / Invert). You will get a blue and white sphere:

We will now
add the exploding rays. For this we first need the sphere streched on the
layer: Filters / Distorts / Polar coords. Disable the bottom-right checkbox
"To Polar". Click OK.
Then go to Image / Transform / Rotate 90° CW.

Click Filters
/ Distorts / Wind with the values:
Wind
Direction: Right
Edge affected: Leading
Threshold: 5
Strength: 37
Use the filter again by pressing CTRL+F.

Now we must
undo the stretching from before to get our sphere:
- Turn the Layer by selecting Layer / Transform / 90° CCW. It should now be on
the top side.
- Now select Filters / Distorts / Polar coords. Check the box for "To Polar"
again.

Now it looks
quite cool.
Select the Blend
tool. Search for the Incandescent gradient as seen on the picture.

Turn it around
and go to Colors / Map / Gradient Map and you have your exploding
planet!
Optionally, you could duplicate the planet layer. Soften this layer with the
value 11, turn the transparency of the layer to 65% and change the layer mode
to "screen" or "color". Thus, it reached a little more color intensity and
softer transitions. Have fun with it.
