A pair of clear glass balls, each more than half an inch thick, have been spotted in the impact crater near the moon. South Pole. TIt is the first of its kind to be found on the moon.

new Research In the Science Bulletin he describes “the first detection of a macroscopic and transparent glass ball on the Moon.” It is possible that the beads were formed by the heat generated by the violent effect Or maybe from early volcanic activity. Results are importantbecause the glass ball “records important information about mantle formation and the history of lunar volcanoes and impact craters,” according to the study.Dipimpin oleh Zhiyong Xiao, aAssociate Professor di Planetary Environmental and Astrobiological Research Laboratory Universitas Sun Yat-sen di Guangzhou, China.

“Transparent glass ball,” say scientists Describing them, they were spotted by the eight-wheeled Yutu.2 explorers. adventureras part of China The Chang’e 4 mission is currently investigating the chemical differences (the lunar equivalent of a “geologist”) and the chemical differences between the near and far sides of the Moon. The small rover landed 115 miles (186-kilometer) Von Kármán Crater on January 3, 2019. This large crater is located inside a much larger crater Aitken Basin– Largest lunar impact basin – near the south pole of the moon.

it’s Yutu-2 Glass stumbling is hardly special, with objects scattered over much of the moon’s surface. What makes this special item unique is its large size and translucent nature. Moon glass tends to be small, measuring less than 1 mm (0.04 in), but the Apollo astronauts managed to find some large beads like this one. The two balls in the von Karmann nozzle measure between 0.5 and 1 inch (1.5 cm-2.5 cm), hence its description as “macroscopic” in size.

But while the Apollo samples were dark and dim, the newly discovered beads were “transparent or semi-transparent and exhibited a vitreous luster,” the researchers wrote. Four other similar things had been discovered by Yutu-Panoramic camera 2, but the image resolution is not clear enough for scientists to be able to identify it as a glass ball.

Indicate the shape and location of these balls They are effect glasses, aren’t they Objects sent from other planetary objects or products volcanic activity. The glass ball is formed from the intense heat of the great shock, as the silicates are melted and spherical when transmitted through the air. The liquid ball is thrown into the sky, and cools down rapidlyback to the glass-like surface.

Volcanic eruptions can do the same, but volcanoes haven’t been active on the Moon for some time. What’s more, the nature of these beads isn’t exactly consistent with volcanic activity, the scientists say, arguing that they were glass collisions caused by “anorthosic melting.” Lunar anorthosite is a type of igneous rock common in the lunar highlands near the South Pole. A limitation of the paper is that the exact composition of the beads cannot be determined.

Scientists say that glass beads were formed recently or were recently exposed. The top of the lunar regolith closed in less than 100,000 years, “suggesting that the grains may be very small,” according to the paper. The recent collision event likely caused the beads to move, depositing them on the surface.

A similar object was found on Earth, and was named tact. Scientists suspect that this macroscopic Things are common features of the moon and that other spheres “will abound in the heights of the moon.”
