Io, one of Jupiter's moons


Images of Io, one of Jupiter's moons, captured by the Keck Telescope

These images of Io, one of Jupiter's moons, were captured by the Keck Telescope. Surface details captured with Keck adaptive optics (AO) 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 AO (lower right) shows what the Keck Telescope would see without this technology. Note that no hotspots are detected in this image.

The Center for Adaptive Optics (CfAO), located at the University of California, Santa Cruz, is a National Science Foundation Science and Technology Center (STCs). Initial funding began in 2000. CfAO researches AO 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, microelectromechanical systems technology and retinal imaging.
