Gemini North infrared image of Saturn and Titan (at about 6 o’clock position). Image obtained on May 7, 2009 (5:31 UTC), using the Altair adaptive optics system with the Near-infrared imager (NIRI). Color composite image made using data from three infrared filters (K’ [2.0-2.1 microns], h210 [2.12 mircon narrowband], and bracket gamma [2.17 micron narrowband]), field of view is about 40 arcseconds across.
At the edges of Saturn’s ring, the F-ring is faintly visible. The F-ring was discovered in images from the Pioneer 11 spacecraft in 1979 and is normally not apparent in images taken with ground-based telescopes. Also apparent are several of Saturn’s smaller moons.
