Here is some code to create an image of space.

import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
import java.awt.Color;
/**

*
* @author (your name)
* @version (a version number or a date)
*/
public class MyWorld extends World
{

/**
* Constructor for objects of class MyWorld.
*
*/
public MyWorld()
{
// Create a new world with 20x20 cells with a cell size of 10x10 pixels.
super(400, 400, 1);
GreenfootImage bg = getBackground();
bg.setColor(Color.BLACK);
bg.fill();
createStars(200);
}

private void createStars(int numberOfStars)
{
GreenfootImage bg = getBackground();
bg.setColor(Color.GRAY);
for (int i = 0; i < numberOfStars; i++) {
int x = Greenfoot.getRandomNumber(getWidth() );
int y = Greenfoot.getRandomNumber(getHeight() );
bg.fillOval(x,y,2,2);
}
}
}
