New research suggests that volcanoes were still erupting on the moon when dinosaurs roamed Earth
FILE - This Dec. 2, 2020, file image taken by panoramic camera aboard the lander-ascender combination of Chang'e-5 spacecraft provided by China National Space Administration shows a moon surface after it landed on the moon. Volcanoes were still erupting on the moon when dinosaurs roamed Earth, new research suggests.and brought to Earth in 2020 by a Chinese spacecraft.
Images from NASA's Lunar Reconnaissance Orbiter in 2014 had also suggested more recent volcanic activity. The glass beads are the first physical evidence, Stopar said, although more research is needed to confirm their origin. The Chang’e 5 samples were the first moon rocks brought to Earth since those collected by NASA's Apollo astronauts and by Soviet Union spacecraft in the 1970s. In June, China returned samples from theThe research may help us understand how long small planets and moons — including our own — can stay volcanically active, study co-author He Yuyang from the Chinese Academy of Sciences said in an email.
Researchers studied around 3,000 lunar glass beads smaller than a pinhead and found three with signs they came from a volcano. Glass beads can form on the moon when molten droplets cool after a volcanic eruption or meteorite impact. Existing time lines suggest the moon had already cooled off past the point of volcanic activity by the time frame suggested by the new research, Stopar noted.The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Science and Educational Media Group.
