NOEMA, a new vista on the invisible

NOEMA (NOrthern Extended Millimeter Array) is the most powerful millimetre radio telescope in the northern hemisphere. Located on the Bure plateau, in the Hautes-Alpes, the observatory will eventually consist of 12 antennae that will form a single large radio telescope capable of revealing the invisible thanks to interferometry.
Equipped with a new generation of receivers and electronics, these antennas will be able to capture the coldest light emitted by the universe, around 250°C. The astronomer Frédéric Gueth explains how the millimetre waves emitted by celestial objects are a mine of information on the most remote regions of our universe, as well as on the life and evolution of galaxies.
