These images of Io, one of Jupiter's moons

May 11, 2010
These images of Io, one of Jupiter's moons, were captured by the Keck telescope. Surface details captured with Keck adaptive optics in the K-band (upper left) show a comparable level of detail to the visible light picture taken with the NASA Galileo orbiter (upper right).

The L-band image (lower left) is dominated by active volcanic hot spot emissions, such as Loki, located near the center of the disk. These spots can now be monitored from the ground. An image of Io without adaptive optics (lower right) shows what the Keck telescope would see without adaptive optics. Note that no hot spots are detected in this image.

The Center for Adaptive Optics (CfAO) is one of 11 Science and Technology Centers (STCs) currently funded by the National Science Foundation. Initial funding began in 2000. CfAO researches adaptive optics in the fields of vision science and astronomy to remove the effects of image blurring through turbulent media. Applications include astronomical telescopes, laser guide stars, wavefront sensing, MEMS technology and retinal imaging.
