The Moon has been a subject of awe and fascination for millennia, with its shape-shifting powers and enigmatic dark side. And though it’s the one celestial body on which man has taken (small) steps, we still have big leaps to go in understanding its potential and uncovering its secrets. However, one hidden feature of the Moon has been unearthed by scientists and it’s very, very big, and very, very heavy. Buried beneath its South Pole-Aitken basin – one of the largest preserved craters in the Solar System – is a structure which weighs at least 2.18 billion kilogrammes and measures more than 300km (186 miles) in depth and 2,000km (1,243 miles) in length.

"One of the explanations of this extra mass is that the metal from the asteroid that formed this crater is still embedded in the Moon's mantle,” lead author Peter B. James, from Houston’s Baylor University, said in a statement shared with IFLScience. Illustrating just how gigantic this thing is, he went on: "Imagine taking a pile of metal five times larger than the Big Island of Hawaii and burying it underground. That's roughly how much unexpected mass we detected.” The groundbreaking finding was made thanks to NASA’s Gravity Recovery and Interior Laboratory (GRAIL) mission, which measures changes in the Moon’s gravitational field. Data collected by GRAIL can then be used to study the internal composition of our cratered companion. The South Pole-Aitken Basin has been at the centre of numerous investigations because of just how unique it is. The region offers clues both on the interior composition of our closest satellite and its history, and who knows what other mysteries it holds... Have your say in our news democracy.

Google says it has made a major artificial intelligence breakthrough that could dramatically reduce the climate impact from flying. The company partnered with an airline and data provider to build a new artificially intelligent system that looks to reduce the amount of contrails produced by planes. Contrails are the long, white lines that appear behind planes, and can sometimes make the sky appear cloudy. They are formed as soot from planes’ exhausts turn into ice – and when they merge together, they trap heat in the atmosphere and warm the Earth. Those contrails account for more than a third of the global warming impact of flying, according to the UN. If planes are able to avoid flying through areas that create contrails, however, then they will reduce the amount of warming. If the human-made clouds can be stopped, then their warming effects can be reduced. In an attempt to do so, Google researchers gathered satellite imagery, weather and flight path data and fed it into an AI system. That was then used to try and generate routes for pilots that avoided creating those contrails. Pilots at American then flew some 70 test flights over a period of six months, Google said, following those AI-generated routes. The researchers then examined satellite imagery and found that the contrails produced were reduced by 54 per cent. “This is the first proof point that commercial flights can verifiably avoid contrails and thereby reduce their climate impact,” Google said. The company did also note that the flights burned 2 per cent additional fuel, though Google suggested that the flights could be selectively chosen. Google said it would be “working across the aviation industry to use AI to make contrail avoidance a reality over the coming years” in its announcement. It said it has the “potential to be a cost-effective, scalable solution to reduce the climate impact of flying”. Airlines are currently not charged for their climate impact, however, and there is therefore no indication that they would opt to use the routes that help reduce global warming.

Scientists are learning new things all the time about the early days of life on Earth, and a new discovery could change our understanding of evolution in our oceans. Algae are among the most vital life forms of the planet today – and new research into algae’s ancient ancestors makes for intriguing reading. Palaeontologist Tom Harvey from the University of Leicester believes he’s found fossilised phytoplankton which was key to the makeup of the oceans 500 million years ago. A new study authored by Harvey and published in the journal Proceedings of the Royal Society B focuses on samples he found in rock from Newfoundland, Canada, While there’s more known about the early animals that dominated the food chains at that time, the smaller organisms around 500 million years ago are still relatively unstudied. Harvey’s research focuses on the microscopic creatures – and it all came about by chance. While he was actually looking for animal skin in rocks using a microscope, he instead stumbled upon collections of geometric clusters, which he later concluded were ancient forerunners to algae. “The cells were quite big, they formed quite a large colony that has this amazing geometry,” he said. “It was just too mysterious. I didn’t even want to hazard a guess.” According to Harvey’s findings, it’s evidence that the animals at that time filtered seawater for phytoplankton – which would mark the earliest evidence of them doing so, which is vital to the makeup of ocean ecosystems. Like today’s life forms, it’s thought that chemical signals sent by nearby animals caused the ancient samples to divide and grow. It also fills a space in the records of phytoplankton and helps to paint a well-rounded picture of evolution over time, given that the phytoplankton we see today only traces back around 200 million years ago.
