The B-rolls are video shots and sequences of situations at different angles, which visually tell stories, illustrating different subjects.

The B-rolls that we present below show various daily realities in ALMA and can be very useful for press media and documentary makers who need to create stories without having to go to film them.

The themes of these eight (8) B-rolls range from safety, location, technology, flora and fauna and facilities, to name a few.


Most observatory activities take place in the Operations Support Facilities, located 2,900 meters above sea level, in the Los Andes mountains near San Pedro de Atacama. Due to the altitude and... See more

Medical Check-ups

The ALMA staff spend most of their time at the Operations Support Facility (OSF) at 2,900m, but some of them must work on the antenna maintenance and relocations at the Array Operations Site (AOS) at... See more

Flora and Fauna

Despite its similarity with a Martian landscape, the Atacama Desert is home to native flora and fauna, which over centuries have developed techniques to adapt to the rugged living conditions. ALMA workers... See more

ALMA Receivers: Front End

To capture the cold Universe, ALMA has sophisticated receivers that must operate at extremely low temperatures (-269 degrees). This freezes or reduces the “thermal noise” to capture the weak signals from... See more

Unique Location

After searching the world over to find the perfect place to capture millimetric and submillimetric waves, scientists identified a plateau where the conditions were unmatched: Chajnantor, in northern... See more

Safety First

Worker safety at ALMA is paramount. For this reason, different activities at the observatory are regulated and supervised. For example, portable oxygen tanks are given to all workers who ascend to... See more

ALMA Technology

ALMA uses different technologies to make it possible to observe the cold and distant Universe. For example, without an ALMA correlator, ALMA could not combine the information collected by the... See more

Working at Heights

To maintain antennas and move them on the Chajnantor Plateau, ALMA workers must ascend to 5,000 meters above sea level. This extreme altitude requires workers to be in optimum health, and to... See more

Public Visits

ALMA is open every Saturday and Sunday morning to members of the public who want to visit its facilities located in northern Chile (50 km from San Pedro de Atacama). Only those visitors who are... See more
