Marduk​

Io

In the shadow of Jupiter, New Horizons also saw an activity by Marduk (bright red dot on the bottom right).

The Marduk is a volcano on the Jupiter moon Io . It was named in 1979 after the Sumerian deity Marduk . In that year, the Voyager 1 space probe first detected active volcanoes on Io. Marduk was identified as the source of an eruption column .

features

The volcano is considered to be very active. The surrounding region is considered a hotspot . It is often covered with dust. The ejected lava allows conclusions to be drawn about the inner structure of the moon and the forces acting on it, which are responsible for the seismic activities. During the flyby of the Galileo probe in 1996 it was evident that Marduk is a crevasse volcano about 250 km in length. From a caldera-like depression, lava flows northwards into about 200 km of extensive lava fields called Marduk Fluctus. The area around the volcano is reddish in color , presumably due to deposits of sulfur . During the eruptions, a lot of material is ejected, which cools down quickly in space. Presumably these particles are responsible for the red color of the neighboring moon Amalthea .
