Mobile Dyson shell recently discovered by IR astronomy in intergalactic space approximately 23 million ly away. The Traveler is moving through intergalactic space at a rate of 0.5 c on a heading of roughly 87 degrees perpendicular to a line drawn between the Milky Way and the Virgo Cluster. No signals or non-infrared emissions have been detected. The origin, purpose, or destination of the Traveler are unknown.
