Dr. Bolton: “It will be a very valuable resource.”

[서울=뉴시스] Intern Reporter Soo-min Lee = NASA, the American space agency, discovered traces of twin volcanic plumes while taking close-up photos from the “Io” satellite orbiting Jupiter.

NASA posted photos of Io on its website on the 7th (local time) and said: “The Juno probe, which orbits Jupiter, entered about 930 miles inside Io’s surface. The photos taken show active plumes, high mountain peaks and lava.” “There are volcanic islands that testify to the presence of a lake,” she explained.

Previously, the New York Times (NYT) reported on the 6th that Juno had succeeded in taking close-up photos of Io, Jupiter’s third largest moon and the most volcanic planet in the solar system, after its second attempt.

In this image, NASA announced that it has captured twin volcanic plumes erupting into space from the lunar surface.

According to Scott Bolton, a physicist at the Southwest Research Institute who led the study, Io’s surface is orange, yellow and blue, similar to the surrounding Hawaiian volcanoes. He said this phenomenon was the result of Io’s violent expulsion of sulfur and other compounds.

NASA noted that while the Moon’s atmosphere is composed mostly of carbon dioxide, Io’s is likely composed of molten sulfur or silicate rocks. And as to the reason for the volcanic activity, he said, “Io is caught in a tug-of-war between Jupiter’s powerful gravity and the pull of nearby moons, which churn its interior and produce eruptions of lava that coat its surface .”

Some foreign media said it was not surprising to compare Io’s surface to “hell” and called the newly discovered volcanic pillar “the volcano of hell.”

“The goal is to understand what is really behind the engines that drive all volcanoes,” said Dr. Bolton, stressing that the data from this expedition will be very valuable.

According to the NYT, this will be the last close flyby of the Juno spacecraft, but it is reported that remote observations will continue every 60 days.
