A Jupiter-Io Montage from New Horizons
Explanation: As the New Horizons spacecraft sweeps through the Solar System, it is taking breathtaking images of the planets. In February of last year,
New Horizons
passed Jupiter and the ever-active Jovian moon
Io
. In
this montage
, Jupiter was captured in three bands of
infrared light
making the
Great Red Spot
look white. Complex
hurricane-like ovals
, swirls, and planet-ringing bands are visible in
Jupiter's complex atmosphere
. Io is
digitally
superposed in natural color. Fortuitously, a plume was emanating from
Io
's volcano
Tvashtar
. Frost and sulfuric lava cover the volcanic moon, while
red-glowing lava
is visible beneath the
blue sunlight-scattering
plume. The robotic
New Horizons spacecraft
is on track to arrive at
Pluto
in 2015. Note:
