JAKARTA – The Juno space vehicle provides a clearer view of Jupiter’s moon Io. Scientists now know how large the lava lake is on Io and the volcanic processes on the moon. This new knowledge was successfully discovered by Juno’s Jovian Infrfied Aurora Mapper (JIRAM) instrument. The results were studied and reported in the form of a paper published in Nature Communications Earth and Environment. Juno crossed the Io twice last year, namely in May and October. The viewing distance is different. Juno was at an altitude of 35,000 kilometers in the first month, while in the second month Juno was at an altitude of 13,000 kilometers. From this distance, JIRAM managed to find the existence of a luminous ring that surrounds the base of a number of hot spots. The infrared image resolution of JIRAM shows that the
In addition to showing the presence of a lava lake inside the caldera, the JIRAM infrared also found a thin lava circle that borders the central bridge and the walls of the lake. The lava kerac should have erupted because it hits the wall of the lake by force. “(This lava kerac) forms a typical lava alliance seen in the Hawaiian lava lake. The walls are probably as high as hundreds of meters, which explains why magma does not usually appear to flow out of paterae – bowl-shaped figures formed by volcanism,” Mura said. Based on the results of these findings, the hypothesis about the surface of the O is still the same. “Magma flooded into the middle of the lake, spread out and formed and formed troughs flowed along the lake, rising the lava.”
