New research suggests that volcanoes on the Moon were active during the time of the dinosaurs on Earth, but much more recently than previously believed.
Three small glass beads gathered from the lunar surface by a Chinese probe in 2020 indicate volcanic activity on the Moon 120 million years ago, according to the study. The findings were published Thursday in the journal Science.
Initial analysis of samples collected by the Chang’e-5 lunar mission suggested that volcanic activity ceased approximately 2 billion years ago, updating an earlier evaluation that the Moon had been devoid of active volcanoes for about 4 billion years.
Researchers examined around 3,000 lunar glass beads that may have been produced by volcanic eruptions or meteorite impacts, identifying three of them as of volcanic origin based on their texture and chemical makeup.
The research team expressed being “surprised and excited” by their “unexpected” discoveries.
The presence of relatively recent lunar volcanism “implies that a small celestial body like the Moon may have retained enough internal heat to support activity until very late,” co-authors Professor Li Qili and Associate Professor He Yuyang from the Institute of Geology and Geophysics, Chinese Academy of Sciences, shared in an email.
However, it remains “unclear” why the Moon has remained volcanically active for such a long period, as per the study.
Planetary volcanologist Qian Yuqi from the University of Hong Kong commented that identifying such a young volcano has “major” implications for the Moon’s development.
“Where did they originate from?” Qian, who was not part of the research, inquired in an email. “This could lead to future missions to search for them.”
The Chang’e-5 lunar mission marked the first return of lunar samples since the U.S. Apollo program in the 1970s and the Soviet Union’s Luna 24 mission. In June, China achieved a historic feat by retrieving rocks from the far side of the Moon through its Chang’e-6 mission.
