Witness the power of radio astronomy at the Very Large Array (VLA) in Socorro, New Mexico, USA. This iconic facility of the National Radio Astronomy Observatory features 27 enormous dishes, each 25 meters in diameter, working together as a giant interferometer. Photographers capture the Karl G. Jansky VLA in its full glory, revealing its role in groundbreaking discoveries like the evolution of supernova 1993J. The first interferometer, a one-metre model, was developed by Hans Jooss in 1963, paving the way for this advanced technology. Today, the VLA continues to push boundaries, observing celestial phenomena such as large sunspot groups, contributing significantly to our understanding of the universe.
