c/7 orthogonal spaceship
Josh Ball has discovered a microscopic orthogonal spaceship with a new velocity, namely c/7. It is the slowest orthogonal spaceship, which (together with its loaf-pushing behaviour) led to it being named 'the loafer'. Adam P. Goucher discovered how to synthesise it with 18 gliders; this was further reduced to 8 by Matthias Merzenich. Shortly afterwards, a gun was engineered to repeatedly emit the spaceship.
A summary of the known orthogonal spaceship speeds is given in the following diagram, using Ford circles to represent rational numbers:
