Astronomers from MIT and ASU have
detected faint radio signals coming from the Cosmic Dawn — the time when the first stars began to flicker on (Credit: CSIRO Australia)
ALMA is a telescope suitable for analyzing molecules in galaxies because of: 1) a high sensitivity to
detect faint radio signals; 2) a high fidelity imaging capability to image actual gas distributions; 3) the ability to observe wideband multiple wavelengths simultaneously, and high spatial resolution.
