This image from a prototype radio telescope system shows the moon’s Hadley C crater and the Hadley Rille, a canyon believed to be a collapsed lava tube. The area is also the landing site of the 1971 Apollo 15 mission. (COURTESY NRAO, GBO, RAYTHEON)
ALBUQUERQUE, N.M. Imagine a radio telescope so powerful it can “see” high-resolution details of planets at the farthest reaches of our solar system.
After a two-year “proof of concept” test, scientists have demonstrated such an instrument using the powerful Green Bank Telescope in West Virginia as a transmitter, and the continent-wide Very Long Baseline Array, or VLBA, as a receiver.
