Evidence of Widespread Stealth Volcanism
on Io. High spatial and spectral
resolution observations of SO emissions on Io reveal evidence for
widespread stealth volcanism. Click on

Multi-phase volcanic resurfacing at Loki Patera on Io. On 8 March 2015 Europa
passed in front of Io, gradually blocking out light from the moon,
an event observed with the LBTI. Click on

Long-term, Hi-res Tracking of Eruptions on Io. We tracked 48 hot spots on 100 nights from August 2013 through the end of 2015. Click on

Three Massive Outbursts on Io (August 2014). During a 2-week period in
August 2014 we detected three gigantic eruptions on Io with the
Keck and Gemini telescopes. Click on

TVASHTAR AWAKENING (Apr. 2006). Integral-field spectrometer observations detected a powerful volcanic eruption at Tvashtar in April 2006. This eruption was likely the same as detected with the New Horizons spacecraft in Feb. 2007. Click on

SPATIALLY RESOLVED SO ON IO (NOV. 2002)We scanned the NIRSPEC spectrometer across Io while the satellite was in eclipse (see next bullet). This way we obtained the first spatially resolved `map' of SO on Io. Click on

AO OBSERVATIONS OF IO IN ECLIPSE (DEC. 2001)When Io is in eclipse (Jupiter's shadow), no sunlight
is reflected of the satellite, and hence it cannot be used for wavefront sensing. Yet
observations under such circumstances would reveal many volcanic hot spots. Click on

SPECKLE IMAGES OF IO IN ECLIPSE (1998) Speckle images of Jupiter's satellite
Io, while it was in Jupiter's shadow. Click on

MASSIVE VOLCANIC ERUPTION AT SURT (2001) Keck Adaptive Optics images of Io obtained
with the Keck telescope on 19, 20 and 22 February 2001 reveal hot spots and
violent volcanic activity.

KECK AO IMAGES OF IO AT KLM BANDS (2001) Keck Adaptive Optics images of Io at L (3.8 micron)
and M (4.8 micron) bands were taken in December 2001. At these wavelengths the Sun is
much less bright, so volcanic hot spots are easily recognized. Click on the thumbnail
for more images, references and a movie.

DISCOVERY OF SO ON IO WHILE IN ECLIPSE (1999) We discovered a forbidden SO emission band complex
on Io while the satellite was in eclipse. Click on thumbnail for more details and references.
