before. It was taken with a new camera that allows
telescopes on Earth to counteract the effects of
atmospheric
distortion, creating images twice as sharp as the Hubble
space telescope. That makes this one of the sharpest
pictures of the cosmos ever taken.
The new technology works so well, scientists report “it’s
almost like having a telescope with a 21-foot mirror in
space.” For comparison, Hubble’s primary mirror is not quite
8 feet in diameter (2.4m).
