The volcanic gas on Jupiter’s moon has a thin atmosphere that collapses in Jupiter’s shadow. Apart from that, it also sometimes condenses as ice.
According to a new study by researchers funded by NASA, Jupiter’s moons give off gas. Researchers reveal about the freezing effect of Jupiter’s shadows. Occurs during the daily eclipse of the lunar volcanic gases.

Research on Volcanic Gases on Jupiter’s Fluctuating Moon
This extraordinary phenomenon is the first time scientists have discovered directly. This will provide insight into the geologically active moon.
Launching from nasa.gov, there are volcanically active objects in the solar system. Volcanoes come from tidal heating. Moreover, it is the result of the gravitational force of Jupiter and other moons.
Constantine Tsang, a researcher at the Southwest Research Institute in Boulder, Colorado. The results of his study of volcanic gases on Jupiter’s moon have been published in the Journal of Geophysical Research.
The force of gravity will produce geological activities such as volcanoes. The mountain emits feathers like an umbrella for sulfur dioxide gas. Length reaches 300 miles or about 480 kilometers.
The result is vast basaltic lava fields that can flow for hundreds of miles. The atmosphere of Jupiter’s moon is dominated by sulfur dioxide gas. Its main source comes from volcanic activity.
Atmospheric changes occur on the giant planet Jupiter. After the gas is emitted from the mountain, it then collapses as SO2 freezes to the surface as ice.
Then it will recover when the ice is warm and sublime. Changing from solid back to gas as the moon moves around. The movement from the eclipse back to sunlight.

The Gemini and TEXES telescopes
Major research studies of volcanic gases on Jupiter’s moons using the large 8-meter Gemini North telescope in Hawaii. Its support is the Texas Echelon Cross Echelle Spectrograph or TEXES instrument.
When the temperature drops from -235 degrees Fahrenheit in the sun to -270 degrees Fahrenheit during an eclipse. So Jupiter’s atmosphere began to deflate.
Every two hours an eclipse occurs. During a full eclipse, the effective atmosphere collapses. This is because most of the sulfur dioxide gas settles into frost on the surface of the moon.
Conditions will develop again when the surface warms up. When the moon returns, there is full sun. The volcanic gas on Jupiter’s moon is collapsing and undergoing constant repair.
Most of the atmosphere comes from the sublimation of SO2 ice. Although the volcanoes on Jupiter are hyperactive, they are a major source of SO2. Each day the sun’s rays control the atmospheric pressure by the temperature of the ice on the surface.
Prior to conducting the research, there were no direct observations of the atmosphere on Jupiter. During an eclipse, Jupiter’s atmosphere is difficult to observe in the darkness of its shadow.
However, the existence of TEXES can measure the atmosphere using heat radiation. But not from the sun. Meanwhile, the Gemini telescope can find out the faint message signs of Jupiter’s atmosphere that is collapsing.
Atmospheric Impacts Due to Volcanic Activity
Astronomers use ALMA to create snapshots of the moon as it passes in and out of shadows. The goal is to distinguish between the various processes that give rise to the atmosphere and volcanic gases on Jupiter’s moon.
The moon will enter Jupiter’s shadow and come out of direct sunlight. If the sulfur dioxide gas is cold, it will condense to the surface. During this time, sulfur dioxide can be seen.
Thus, the researchers could see how much impact the atmosphere had due to volcanic activity. The resolution and sensitivity of the ALMA bore fruit. Obviously, plumes of sulfur dioxide and monoxide are rising from the volcano.
Astronomers can calculate that active volcanoes can make up 30% to 50% of the atmosphere. In previous studies Jupiter had been visited by spacecraft. The robot provides a very detailed view. However, the observation is only fleeting.
Joe Pesce, director of programs in the NSF Division of Astronomy, said observations from Earth would require a longer study.
Advanced technology is needed to improve observations. So that it can be revealed various events in this universe, such as volcanic gas on Jupiter’s Moon. (R10 / HR Online)
