Io

Io, the volcanic moon of Jupiter, as imaged with the VLT NAOS-CONICA Adaptive Optics instrument on 5 December 2001, through a near-infrared, narrow optical filter (Brackett-gamma at wavelength 2.166 µm). Despite the small angular diameter of Io, about 1.2 arcsec, many features are visible at this excellent optical resolution.
