In front of the wide universe, humans are often surrounded by a sense of isolation that there are few things that are alive and moving. We deliver news that may be comforting to us.
On March 15, NASA reported volcanic activity on Venus. It was found that the shape and size of the volcanic vent area, which was photographed by NASA’s Magellan spacecraft in the 1990s, has changed over the past year. This is the first time geologically direct evidence of active volcanic activity has been obtained.
Robert Herrick, who led the study, said, “We saw geopolitical changes caused by volcanic activity in two pictures taken over eight months.” He found a clear difference between October 1991 and February 2023 in the vents of Maat Mons, one of the largest volcanoes on Venus. For the study, the photos of the Magellan spacecraft were compared one by one for regarding 200 hours. During the comparison, the photos were taken from different angles, which made analysis difficult, but computer modeling solved this problem.
This makes it clear that Venus experienced a volcanic eruption just 30 years ago. It is also important to look at what geopolitical changes will occur from the surface to the center of a planet that has undergone volcanic activity following this study. Indeed, public attention is focused on what secret clues the news of the volcano’s active volcano will bring.
