Combined Array for Research in Millimeter-wave Astronomy

The Combined Array for Research in Millimeter-wave Astronomy consisted of 23 radio telescopes of varying sizes arranged in a remote mountain setting in California. These instruments worked together to detect and measure radiation from distant space objects at millimeter wavelengths.

The facility opened in the early 2000s as a partnership between major research universities across California and the Midwest. This collaboration brought together resources and expertise to advance observations of the cosmos.

The site served as a meeting point for astronomers from different research institutions who shared a common goal of studying distant cosmic objects. This collaborative environment shaped how scientists worked together and exchanged findings at this remote mountain location.

The site is located at high altitude in a remote mountain area well suited for observing the sky. Visitors should prepare for the conditions typical of this elevated, sparsely settled region.

The facility employed special techniques to overcome atmospheric water vapor interference, allowing precise measurements at extremely short wavelengths. This capability made it possible to detect fine details of objects so distant they would otherwise be barely observable.
