Abstract
Mediums which do not support the propagation of plane waves with negative phase velocity (NPV) when viewed at rest can support NPV propagation when they are viewed in a reference frame which is uniformly translated at sufficiently high velocity. Thus, relativistic negative refraction may be exploited in astronomical scenarios.
