Astronomers Propose a 50-Meter Submillimeter Telescope

The Atacama Large Millimeter/submillimeter Array (ALMA) in northern Chile is our most powerful radio telescope. But astronomers are hungering for a new radio telescope made of one massive dish. Image Credit: A. Marinkovic/X-Cam/ALMA (ESO/NAOJ/NRAO)

Some parts of the Universe only reveal important details when observed in radio waves. That explains why we have ALMA, the Atacama Large Millimetre-submillimetre Array, a collection of 7-meter and 12-meter radio telescopes that work together as an interferometer. But, ALMA-type arrays have their limitations, and astronomers know what they need to overcome those limitations.

They need a radio telescope that’s just one single, massive dish.
