Undo and Navigation Steps

Alternatively, click a previous snapshot in the History Palette.
Navigate (zoom in and pan) your image using the Navigator Palette,
or the Zoom Tool. 
Activate The Hand Tool by tapping the Spacebar, keeping the Spacebar pressed, pan your image in the usual way. 
1/
Open a New document and set the following attributes.
2/
Then set the Background swatch to a colour you wish your star burst to be - I am choosing Red.
3/
Now, from the toolbar, activate the Rectangular Marquee Tool.
And set the following attributes into its Options bar.
Then drag out a single vertical marquee, as illustrated below.
4/ Quick Fills
To fill the transparent marquee with the Background colour, press and hold your keyboard’s Ctrl key, then tap your Backspace key.
Repeat Chapters 3 and 4, subsequently creating multiple vertical marquees of varying widths; filling each marquee with the Background colour. When you have finished this, press Ctrl then D to remove the selection marquee, and you are ready for the next step.
Note
For personal results, experiment with different widths and create a star burst that suits your needs.

From the top menu, choose Filter then choose Distort, then choose Polar
Co-ordinates. In the subsequent Polar Co-ordinates dialogue box, set the following attribute, then click OK.

To smooth ragged edges, use a very low Strength of the Blur Tool.
Alternatively, from the top menu, choose Filter then choose Blur then choose Gaussian Blur. In the Gaussian Blur dialogue box, set the lowest Radius that smoothes the ragged edges, then click OK.

For symmetry, activate the Polygonal Lasso Tool, and with a Feather of 0, click a lasso line around the area you wish to effect - as illustrated below.
Then press Ctrl and your Backspace key to fill the selected area with the Background colour - in my case, this is White.
14/
To apply a swirl effect, from the top menu, choose Filter then choose Distort then choose Twirl. In the subsequent Twirl dialogue box, experiment with the Angle slider and find a look you like.
