Image of Io with Adaptive Optics at the Gemini North Telescope (image) Gemini Observatory Share Print E-Mail Caption This image of Io was taken in the near-infrared with adaptive optics at the Gemini North telescope on Aug. 29. In addition to the extremely bright eruption on the upper right limb of the satellite, the lava lake Loki is visible in the middle of Io's disk, as well as the fading eruption that was detected earlier in the month by de Pater on the southern (bottom) limb. Io is about one arcsecond across.
