Features:

• Each new telescope increases the scan area of the galaxy by 90000 * Pi.
• The scanning radius is calculated by the formula:
  R = 300 * Sqrt(N); where N is the number of telescopes.
  On the galaxy map, the scan radius of telescopes is shown by a green dashed circle.
• You can only see and colonize planets that are in the scanning area of your telescopes, or previously explored with geological probes.
