Scientists Identify Strange Gel-Like Substance On Far Side Of Moon

  • Weird green gel-like substance found on the moon finally identified

This suspicion has now been confirmed in a new study published in the journal Earth and Planetary Science Letters. The unexpected discovery made the past year a moratorium on the planned activities of the rover, which is focused on finding out the nature of the viscous material, something never seen before on the lunar surface.

Now, nearly a year later, a team of researchers at the Chinese Academy of Sciences published a detailed report on the analysis of the substance in the journal Earth and Planetary Science Letters.

Instead, analysis of the imagery and studies of the lunar regolith brought back by Apollo astronauts have proven that the freakish substance is actually rock.

The scientists described the substance as 'dark greenish and glistening, ' and measured it approximately 20 inches (52 cm) wide.

A form of rock, breccia is formed when fragments of rocks or minerals get fused together to form a gel-like structure.

It is really very similar to two samples retrieved by the Apollo 15 and 17 missions, Lunar Sample 15466 and Lunar Sample 70019 respectively. The discovery made the astronomers excited about the new fact as only a limited mission has been able to reach the far side of the moon. "However, the authors do an excellent job of documenting rigorously its approach and assumptions, so that their results can be understood in the context of this problem extremely challenging". Scientists have always been curious about the properties of the lunar soil, or regolith, and understanding how impacts can cause changes and form new materials is a step in the right direction.

The article also pays attention to the surroundings.

By September, China announced that the Yutu 2 lunar rover, which came with Chang'e, had come upon a dark-greenish "gel-like" substance at the floor of Von Kármán crater in the South Pole.

The glistening compound was initial imaged by Yutu-2 in late July of 2019, and discovered the subsequent month on the Yutu-2 push diary posted by Chinese govt-sanctioned science outreach blog Our Area.

Based on the information, researchers suggest that the substance was formed by "impact-generated welding, cementing and agglutinating of lunar regolith and breccia". The ejection of materials from the impact that created the nearby crater Finsen, in effect, is considered as the main source, with possible contributions from the crater Alder.
