You can use brush to prepare similar effect.
Just find brush (assorted Brushes, Natural brushes, legacy brushes folder) with radiuses and click once to prepare star - you can use it some times
Then use another circular brush to add glow effect
Start with a black background and on a new layer make a circle in the centre with a soft brush and then enlarge the brush, reduce the opacity slightly, and make a lighter soft circle
Add a new layer and set brush symmetry to New Dual Axis
Go to the paths panel and change the name of the path to Radial Symmetry 10
On a new layer add a single stroke from the centre outwards. The brush symmetry will make that 10 radiating strokes. Note if you are not using a pen & tablet pressure to control the width and the opacity then go to the brush panel and set the Size and opacity controls to Fade.
Repeat the above a few times on new layers , each time changing the path name to say Radial Symmetry 8, or Radial Symmetry 3 to vary the number of radial strokes (the number can be between 2 and 12)
Finally you can adjust the opacity of the radial layers and transform rotate each to get the effect you want
I hope that helps you
Thank you so much you all, this helped me a lot.
