Spaceships are a special class of oscillators. They are similar in that they are patterns which periodically reappear, but unlike oscillators, a spaceship reappears in a location offset from the previous location. The speed of a spaceship is the ratio of the number of cells moved (both vertically and horizontally) divided by the number of generations between appearances. All known spaceships move either orthogonally, or diagonally. While other directions are possible, none are currently known. The date is when the first example for a particular speed is found. This is not necessarily the date when the smallest example, shown, was found.

All spaceships shown below move to the left/west and, if applicable, upward/north.
