Long Wavelength Array, Figure 1

Caption: Photograph of the 16-element LWDA, with a National Radio Astronomy Observatory Very Large Array (VLA) dish visible in the background. For scale, the individual LWDA antennas are a bit less than 4 feet tall and the largest separation between antennas in the array is about 70 feet. The telescope operates as a "phased array," in which the signals from each of the antennas are combined electronically (requiring no moving parts) such that the beam can point in a new direction or change observing frequency extremely quickly.
