Very Large Array during the 'blue hour'

NSF's Karl G. Jansky Very Large Array is seen here during the "blue hour," the period of twilight when the sun is at a significant depth below the horizon, and the remaining sunlight takes on a mostly blue shade.

[The VLA is part of the National Radio Astronomy Observatory, a facility of the U.S. National Science Foundation operated under cooperative agreement AST 1647378 by Associated Universities Inc.]
