TUCSON, Aug. 22 (UPI) -- U.S. astronomers say a new camera and "adaptive optics" to cancel blurring effects of Earth's atmosphere yield the sharpest-ever photos of the night sky.
Installed on a telescope in Chile's Atacama Desert, the new technology has enabled the capturing of visible-light images twice as sharp as those snapped by NASA's Hubble Space Telescope, they said.
