First radio image of the Moon taken with a 12-meter ALMA antenna. The optical image at left shows the sunlight reflected by the Moon’s surface, whereas the radio image shows the physical temperature distribution of the Moon. The ALMA image clearly shows the temperature distribution of the Moon, including weak radio emission from the dark side of the Moon.
