![]() ![]() ![]() Interestingly, this event, which was the longest recorded by this technique, was not independently reported by any other Io volcanic monitoring technique, despite significant number of observations in support of NASA's Juno mission.”Ī small telescope popular with amateur astronomers was used to detect the volcanic event. “Io is the most volcanic body in the solar system, so its volcanism is the ultimate source of the material. Gas from the event filled Jupiter’s magnetosphere, the region of space dominated by Jupiter’s magnetic field, with excess material until early June,” Morgenthaler said. “The volcanic event occurred sometime between mid-December 2017 and early January 2018. ![]() Helens in 1980, which released lots of gas and dust, rather than Kilauea’s recent eruptions in Hawaii, which produce lots of hot lava,” Morgenthaler said. ![]() To use some well-known Earth analogies, this volcanic event may have been from an eruption more like that of Mount St. “Lack of a strong infrared counterpart to this event tells us something about the geology of Io. “These results highlight the growing body of evidence that the traditional way of monitoring Io's volcanism – by looking for temperature changes on its surface caused by hot lava – is not able to reliably find these large gas release events,” said Jeff Morgenthaler, a senior scientist at the Planetary Science Institute and lead author on the paper “Large Volcanic Event on Io Inferred from Jovian Sodium Nebula Brightening.” A large volcanic event was detected on Jupiter’s moon Io using Jovian sodium nebula brightness variation, a new paper in Astrophysical Journal Letters said. The strong magnetic field of Jupiter traps the ring of sulfur ions, known as the Io plasma torus, shown in the right panel. The animation shows the dynamic nature of the system: Io orbits Jupiter every 1.5 days and Jupiter rotates every 10 hours. Visit to see a video animation of sodium (left) and ionized sulfur (right) emission around Jupiter (under black strip) recorded by PSI's Io Input/Output facility (IoIO) over a three-month period. An Astro-Physics 1100 mount, 80mm offset guide scope, and associated software enable the system to acquire and guide on Solar System targets robotically. Io with Volume 25.32 x 10 9 km 3 has Density of 3.528☐.006 g/cm 3 and Surface Gravity is 1.IoIO consists of a 14-inch (35 cm) Celestron Schmidt-Cassegrain telescope feeding a custom-built coronagraph. Io is a Moon of Jupiter, has Mass 89.3 x 10 21 KG which is nearly 0.01495 times the mass of Earth and Mean Radius is 1821.6☐.5 kilometer about 0.286 times the radius of Earth.
