China's Yutu-2 is a robotic mission to the dark side of the Moon launched on December 7, 2018. On January 3, 2019, it completes the first-ever soft landing on the lunar far side. It lands not far from the Moon's South Pole. Scientists are interested in this area. Cold, permanently shadowed craters at the poles contain water ice. These ice patches are uneven and are likely to be ancient. In the south, most of the water ice is concentrated in craters. In a few months, when the scientists were looking through the pictures taken by the rover's main camera, they spotted it - a small crater filled with something that looks shockingly different from the surrounding landscape. Unable to identify the gel-like substance, the team ordered the rover to check this bizarre finding. The nature of the unusually colored finding has remained a mystery for over a year. But finally, the mystery seems to have been solved! #brightside
