Radio dish on the move | Space photo of the day for Aug. 25, 2025

A large white radio dish sits on a transporter with giant wheels that rolls behind a man wearing an orange jumpsuit all in the hot sandy desert.

To peer deep into space, observatories like the Atacama Large Millimeter/submillimeter Array (ALMA) use radio dishes to study cosmic structures at radio wavelengths. But sometimes, to get a better view, these radio dishes need to be rearranged and moved.

This is no small feat, as according to ALMA, the radio dishes weigh up to 100 tons (90,718 kg).
