Jakarta –
Scientists have observed a large volcanic eruption on the surrounding moon Jupiter throughout late 2022. This observation was made by senior scientist at the United States Planetary Science Institute (PSI), Jeff Morgenthaler, using Observatory Input/Output Io (IoIO).
the itself is the innermost satellite surrounding Jupiter and can provide a guide to Jupiter’s volcanic moons.
With remarks by the, Jupiter has been considered the most volcanic planet in the solar system with extreme conditions. This is due to annual outbursts of volcanism caused by the mother planet’s immense gravitational influence.
Observations of volcanic eruptions on Jupiter’s moon
IOIO operated by PSI is located near Benson, Arizona and has been monitoring volcanic activity since 2017.
Using a coronagraph technique that dims the light from Jupiterthe instrument is capable of visualizing a faint gas near the gas giant.
This allowed Morgenthaler to see a second sodium brightness in the cloud or “nebula” around Jupiter that began between July and September 2022 and ended late last year.
Ionized sulfur surrounds Jupiter in a donut-like structure and is referred to as a plasma torus the it becomes sunny also in the months of September-November 2022.
“This could tell us something about the composition of the volcanic activity that produced the eruption or it could tell us that the torus is more efficient at getting rid of material when more material is thrown into it,” Morgenthaler said.
NASA plane sent near Jupiter
Observation IOIO it can then be followed by a NASA spacecraft called Juno that has been orbiting the gas giant since 2016.
Juno should fly by the in December 2023 with its plasma sensitive instruments around Jupiter.
Subsequently, this plasma can be traced to volcanic activity themeaning Juno can tell astronomers if the volcanic eruption in September-November 2022 has a different chemical composition than other eruptions on Io.
Morgenthaler hopes there will be a copy IOIO at various locations around the world to help astronomers monitor Jupiter’s moons from Earth.
With multiple units IOIO it should also allow more time for the plasma torus to cover the and Jupiter’s highly dynamic sodium nebula.
“In addition to studying Jupiter and the elements that surround it, IOIO observing the sodium “tail” following Mercury e planet-planet outside the solar system, an extrasolar planet, as it transits the surface of its star,” Morgenthaler said.
