SUMMARY: Astronomers with the University of Arizona tested a new infrared camera on the 6.5-metre MMTO telescope, and produced an extremely detailed image of planetary nebula IC 2149. The object, located 3,600 light-years away, consists of a cloud of dust and gas shed from a dying star. The image is so clear because of the telescope's adaptive optics system, which removes distortion caused by the Earth's atmosphere - the telescope's secondary mirror changes shape thousands of times a second to compensate for fluctuations in the light.
