Abstract: Advanced civilizations capable of interstellar travel, if they exist, are
likely to have advanced propulsion methods. Spaceships moving at high speeds
would leave a particular signature which could be detected from Earth. We
propose a search based on the properties of light reflecting from objects
travelling at relativistic speeds. Based on the same principles, we also
propose a simple interstellar beacon with a solar sail.
