Hi. This is Marty from Blue Lightning TV.
I'm going to show you how to create this Saturn-like planet in deep space. 
This tutorial is in two parts. In the first part, I'll show you
how to make the star background and the planetary
rings. In the second part, I'll show you how
to create the planetary sphere and how to
create its shadow on the rings. 
I provided this texture so you can follow along. 
Its link is located in the video's description
of project files. We'll use it later to create
our planetary sphere. Create a new document
by going to File and New. Name it "Planet".
Make the Width: 1550 pixels, the Height: 870
pixels and the Resolution: 150 pixels per
inch. The Color Mode is RGB and 8 bits per
channel. Then, click OK. We'll make the background
black. To do this, press Shift + the F5 key
at the top of your keyboard to open the Fill
window. Choose "Black" and click OK. 
We'll fill the background with stars. 
To do this, go to Filter, Noise and "Add Noise". 
Make the Amount 30%, Gaussian and Monochromatic.
Then, click OK or press Enter or Return. 
Go back to Filter, Blur and Gaussian Blur. 
Make the Radius point 3 pixels and press Enter or Return. 
Press Ctrl or Cmd + L to open Levels.
I'll make the Input black: 84 and the Input
white: 178, however, feel free to experiment
with these amount to get the quantity and
brightness of stars that look good to you.
We'll make a new document to create the rings around our planet. 
Go back to File and New.
Name it "Rings". Make the Width: 870  and click OK. 
Go to View and make sure Rulers
and Snap are checked. If they aren't just click on them.
Go to the ruler on the left
and drag out a guide line to the center. It'll
snap to it because we have snap checked. If
you don't see the guide line, press Ctrl or
Cmd + H. Go to the top ruler and drag another guide to the center. 
Open your Gradient Tool and open your Gradient Picker. 
Click the gear icon to open your Gradient presets. Click
"Noise Samples" and click OK to replace the
current gradients with the gradients from
Noise Samples. I'll choose this one, however,
feel free to experiment with any of them.
Click the Radial gradient icon. Go to the
center of the guide lines and press and hold
Shift as you drag across the gradient line
to the edge of your document. Then, release.
Open your Elliptical Marquee Tool and place
your cursor on the top, left corner of your
document. Press and hold Shift as you drag
the selection to the lower, right corner.
Pressing Shift ensures that the selection
will be a perfect circle. We'll make the selection
a bit smaller by going to Select and Transform Selection. 
At the top, you'll see percentages of the Transform's Width and Height. 
If you click the chain-link, it'll lock them together,
so whatever percentage we type into one, will
be repeated in the other. In either the Width
or the Height, type in 97%. Notice they both
have the same percentage. To accept it, press
Enter or Return twice or click the checkmark.
Go to Select, Modify and Feather. 
Feather it 3 pixels and click OK. Press Ctrl or Cmd
+ J to cut it out and copy it to its own layer.
Hide the background by clicking off the eyeball next to it. 
Ctrl-click or Cmd-click on the thumbnail of the top layer to make a selection of its shape. 
Go back to Select and Transform Selection. 
Lock the Width and the Height and
in either field, type in 50%. Then, accept it.
Press the Delete key on your keyboard
to delete the image inside the selection.
Transform the selection again, 
click the chain-link and this time, type in 170%. Then, accept it.
We'll use this selection to delete
a thin ring from the image. To do this, click
the New Layer icon to make a new layer and go to Edit and Stroke. Make the Width: 3 pixels
and tick Center. Then, click OK. 
Ctrl-click or Cmd-click on the thumbnail of the thin ring to make a selection of its shape. 
Make
the middle layer active and press the Delete
key on your keyboard to delete the image inside
the thin ring selection. Make the thin ring
active and Transform the selection. Click
the chain-link, type in 77% and accept it.
Make the middle layer active and press Delete.
To deselect it, press Ctrl or Cmd + D. 
We don't need the thin ring shape anymore, so let's trash it. 
To place your rings into your star background, 
press "v" to open your Move
Tool and drag the rings onto the "Planet"
tab. Without releasing your mouse or pen,
press and hold Shift as you drag it down on
the stars. Pressing Shift kept the rings centered
on the document. Next, we'll place the rings
in perspective. Open your Transform Tool.
Go to a corner and when you see a diagonal,
double-arrow, press and hold Alt or Option
+ Shift as you drag it in approximately this
much. Place your cursor directly on a bottom
corner and press and hold Ctrl + Alt + Shift
on Windows or Cmd + Option + Shift on a Mac
as you drag it out approximately this much.
Go to the top, middle anchor point and when
you see a vertical, double-arrow, press and
hold Shift as you drag it down. Go to a corner
and when you see a curved, double-arrow, rotate
it to an angle you like. To make it bigger,
go to a corner and when you see a straight,
double-arrow, press and hold Alt or Option
+ Shift as you drag it back out. To reposition
it on your document, go inside the Transform
and drag it. If you don't want it to snap
to a position, go to View and click "Snap"
to turn it off. Once you like the size, angle,
perspective and position of your rings, press Enter or Return. 
In Part 2, we'll create the sphere and cast its shadow on the rings.
