VLA antennas

A Piece of the Wye

In this aerial shot over the Very Large Array in New Mexico, nearly the entire array is in view. In this most compact configuration, the Y-shape of the VLA’s tracks is easily seen. We refer to it as the “Wye.”

VLA antenna roller bearings

These roller bearings sit inside the spin gear of every antenna in the Very Large Array (VLA). They support the giant dish and allow it to spin around, but over time, they seize up from flattening or lack of grease. They are replaced or greased while the antenna is split in half inside the Antenna Assembly Building.

VLA antenna and double rainbow

Double Rainbow over the VLA

The Very Large Array may sit in the New Mexico desert, but it’s not always dry. Summer monsoons bring much-needed rains, and this lovely afternoon also brought a double rainbow.

Oxygen Required

Oxygen is required for any staff member spending long periods of time working on ALMA’s supercomputer. The supercomputer is housed close to the telescopes site which sits at an elevation of 16,500 feet in the Chilean Andes.
