+ - Hubble accuracy surpassed by earthbound telescope->

Submitted by randuev
randuev (1032770) writes "High-speed adaptive optics system helped Large Binocular Telescope (on earth) to beat accuracy of Hubble Telescope (space) observations.

"A special sensor detects atmospheric distortions in real time and controls the mirror to adjust its position to compensate, effectively canceling out the blurring. The mirror can make adjustments every one-thousandth of a second, with accuracy to better than ten nanometers (a nanometer is one millionth the size of a millimeter)."

Now, that's what I call real-time. This nifty trick multiplied Strehl ratio (optical quality) of LBT by about 80 times to unprecedented Rayleigh limit. Hope we'll see more space around us in higher resolution on Google Sky."
