The doughnut, called the Io torus, draws its raw material from gases spewed into space by volcanoes on Io, one of Jupiter's large moons. The torus was detected in the 1970s, but almost all of its ...
The Cassini spacecraft has captured the most detailed images ever taken of the Io torus, a doughnut-shaped ring of charged particles that surrounds Jupiter and is replenished by the planet's moon Io.
The image is the sum of 36 extreme ultraviolet images taken over a 10-hour period on Tuesday October 3. Signals from the Io plasma torus and from the Jovian auroral zones are seen.
Known as the Io torus, it lies in Io’s orbit and is at its most dense near the volcanic moon, Io. The best theory for its formation is that Io's volcanoes throw sulphur and sulphur dioxide into ...
However, since 2017, Dr. Morgenthaler has taken a different approach, focusing on the moon’s plasma torus through the Planetary Science Institute’s Io Input/Output observatory (IoIO), in Arizona.
But Europa’s orbit is closer to circular than Io’s, so the internal heating isn’t enough to create volcanoes — just enough to melt vast quantities of ice. 4) The Io torus.
Alice observed the auroral glow from these atoms in Io’s atmosphere and their ionized counterparts in the Io torus. “This UV observation of Io surpasses those from all previous spacecraft to ...
ESA’s Rosetta and NASA’s New Horizons are working together in their joint campaign to observe Jupiter. A preliminary analysis of the data from Rosetta’s Alice ultraviolet spectrometer ...
The atmosphere of Jupiter's satellite Io is extremely tenuous, time variable and spatially heterogeneous. Only a few molecules—SO2, SO and S2—have previously been identified as constituents of ...
NASA’s Cassini spacecraft is helping scientists see the structure and hour-to-hour changes of a giant doughnut-shaped gaseous ring around Jupiter in unprecedented detail. The doughnut, called ...
