New Horizons took this picture of a volcanic eruption
on Jupiter's moon Io
. The plume from the volcano can be seen near the top of the image. The volcano
is named Tvashtar.

Results from the New Horizons Jupiter Flyby
The New Horizons spacecraft is on its way to Pluto. Along the way, it flew past the giant planet Jupiter. When the spacecraft flew by Jupiter, Jupiter's strong gravity gave New Horizons a "slingshot boost" in speed. The extra speed will make New Horizon's trip to Pluto take less time. Still, the spacecraft won't reach Pluto until 2015!
New Horizons blasted off in January 2006. It flew by Jupiter on February 28, 2007. It was going about 21 km/sec (47,000 mph) when it zoomed past Jupiter! But Pluto is very far away. Even at these high speeds, it will take New Horizons about nine years to go from Earth to Pluto.
Scientists took some good pictures of Jupiter when New Horizons flew past the planet. The spacecraft has very good cameras and other instruments.
The New Horizons team also got to practice a planetary flyby. When a spacecraft
flies past a planet, it needs to make a lot of complicated moves. It needs to
point its cameras the right way. It needs to turn instruments on and off at
the right times. And it needs to radio the data it collects back to Earth. The
New Horizons team got to practice all of this at Jupiter. Now they will
be ready when New Horizons finally makes it to Pluto!
New Horizons took lots of great pictures of clouds in Jupiter's atmosphere. It took pictures of the "Little Red Spot". The Little Red Spot is a storm on Jupiter. The Little Red Spot is the "smaller cousin" of Jupiter's famous Great Red Spot.
New Horizons also got some nice pictures of Jupiter's rings. It also studied Jupiter's magnetic field..
New Horizons also took pictures of a few of Jupiter's many moons. It took pictures of the icy surfaces of Europa and Ganymede. It also got some of the best shots ever of volcanic eruptions on Io.
