Scientists have just uncovered billions of years’ worth of secrets buried beneath the surface of the moon. Our celestial companion has been a source of awe and mystery since time immemorial, but now, thanks to China’s space programme, we’re starting to piece together its past. In 2018, the Chang’e-4 lander, of the Chinese National Space Administration (CNSA), became the first spacecraft ever to land on the far side (or the dark side, if you'd prefer) of the moon. Since then, it has been capturing incredible images of impact craters and extracting mineral samples, offering a long-sought insight into the structures that make up the top 1,000 feet of the moon’s surface. Earlier this month, the Chang’e-4’s findings were finally published, and the world was invited to delve deep into the history of our cherished natural satellite. The results, published in the Journal of Geophysical Research: Planets, reveal that the top 130 feet (40m) of the lunar surface are made up of multiple layers of dust, soil, and broken rocks. Hidden within these layers is a crater, which formed when a large object slammed into the moon, according to Jianqing Feng, an astrogeological researcher at the Planetary Science Institute in Tucson, Arizona, who co-led the pioneering analysis. Beneath this, Feng and his colleagues discovered five distinct layers of lunar lava that spread across the landscape billions of years ago. Experts believe that our moon formed 4.51 billion years ago, when a Mars-size object crashed into Earth and broke off a chunk of our planet, as Live Science notes. Over the following 200 million years or so, the moon continued to be pummelled by space debris, with numerous impacts leaving cracks in its surface. Just like on Earth, the moon’s mantle contained pockets of molten magma, which infiltrated the newly formed cracks thanks to a series of volcanic eruptions, Feng explained. However, the new data provided by Chang’e-4 showed that the closer the volcanic rock was to the moon’s surface, the thinner it got. "[The moon] was slowly cooling down and running out of steam in its later volcanic stage," Feng said. "Its energy became weak over time." It is understood that volcanic activity on the moon died out between a billion and 100 million years ago, which means it is largely considered “geologically dead”. However, Feng and his co-authors have suggested there could still be magma buried deep beneath the lunar surface. Chang’e-4 still has much work to do, and Feng and his team hope this is just the beginning of their literally ground-breaking mapping of the moon.

Former Phoenix Suns general manager Lance Blanks has died at the age of 56

Mauricio Pochettino believes Premier League managers should be invited to play a more active role in helping shape refereeing guidelines. Chelsea have been involved in a number of controversial fixtures this season, most notably the frenetic 4-1 win away at Tottenham earlier in November in which Spurs had two players sent off, five goals were disallowed and VAR made nine interventions across a match that lasted over 110 minutes. Pochettino has previously complained that the league’s request to meet with coaches in the week before the beginning of the season to discuss changes allowed little room for constructive input from managers and their clubs. The current campaign has seen a barrage of complaints directed at on-field and VAR officials, with referees coming under almost unprecedented scrutiny following a string of errors, particularly relating to the influence of the video referee on the decision-making process. “We all have full respect for the referees, we understand perfectly that their job is really tough,” said Pochettino, whose team face Newcastle at St James’s Park on Saturday. “But the problem is you get frustrated sometimes during the game because of the VAR. The referee is not responsible sometimes. You cannot complain to the VAR. That is a problem. “I’m going to try and control more my emotions. I think all the coaches respect the referees because they’re in a really difficult situation. “I think sometimes we are frustrated. I think coaches need to be more involved in the decisions, and to work together during the season. “It is not (ideal) to arrive the week before the start of the Premier League season and say, ‘OK, the new rules are this. What do you think?’. Nothing, because you have already made the decision. Like the rule that there can only be one coach (in the technical area). Why? “England was always different about the relationship with the referee. You can talk, you can (previously) have four people in the dugout. Which way do we want to evolve in the Premier League? “England is different. Not only because you drive on the right (of the car), but because of the relationship in football. It is the gentleman’s game.” Despite those frustrations, and the ongoing confusion surrounding the proper implementation of VAR and its interpretation of the game’s rules, Pochettino acknowledged that the emotional side of football is ultimately what props up the business side of the sport. “I think people look at football and understand that it is a big business,” he said. “The sport is very honest, with rules. But around that it is a business that we cannot stop. “If the sport doesn’t produce that emotion it is producing, it is difficult to talk about it in this way, to have the chance to have good salaries, to give also to society. “Football provides people with happiness and that is the most important thing. We are all part of this business.” Read More Pep Guardiola puts Jurgen Klopp on pedestal as ‘by far’ his biggest career rival Ange Postecoglou too busy with football matters to worry about agent-rules probe Many Premier League managers have been in contact after FA charge – Mikel Arteta Cristiano Ronaldo’s second-half brace inspires Al Nassr victory over Al Akhdoud Everton points penalty ‘draconian’ and ‘too harsh’ say Premier League protesters Australia see off Finland to reach Davis Cup final for second-successive year
