Read the transcript from the science podcast 'Horizontes Andinos' about an astronomical observatory in Chile:
'Welcome to our special broadcast from the Atacama Desert in northern Chile. Today, we visit the ALMA radio telescope array, situated at an elevation of 5,000 meters on the Chajnantor Plateau. The observatory operates a synchronized network of 66 high-precision antennas designed to capture millimeter radio signals from the earliest galaxies. Lead systems engineer Mateo Morales explains that this extreme altitude is crucial because the thin, hyper-arid atmosphere minimizes water vapor interference. While the original construction involved an international partnership of 16 nations, current operations are focused on installing upgraded fiber-optic correlators to expand data collection capacity.'
According to the podcast report, what is the exact number of antennas operated by the observatory?
- A16 antennas
- B50 antennas
