ALMA Little Universe

As we have stated in our previous episode, ALMA's multiple receiver bands are used to detect signals from the sky. However, these receiver bands must be kept at very cold temperatures to work properly on their purpose. 
In this episode, Mark Gallilee and Francisco Pino, who work in the cryogenics of ALMA, explain why and how to operate the complex processes by which the receivers of the antennas are kept at extremely low temperatures in the Atacama Desert, the driest of the Earth. 
Let's deepen our understanding of this revolutionary gateway to the distant parts of the Cosmos in ALMA's Little Universe.

What is ALMA Little Universe?

Journey into the 'Little Universe of ALMA' and uncover the wonders of our cosmic origins. In bite-sized episodes ranging from 3 to 6 minutes, delve into the intricacies of the ALMA Observatory, stationed in the heart of the Atacama Desert. Discover galaxies shrouded in stardust, the first-ever image of a black hole, and even a simplified form of sugar, all made possible by 66 colossal antennas that peer into the Universe with unparalleled depth. Embark on this enlightening journey and learn how ALMA connects us to the vast expanse of the Cosmos.
