In South America, intense heat turned the Atacama DesertвЂ™s sandy soil into vast areas of glass stretching for 46.6 miles (75 kilometers) about 12,000 years ago. While the discovery of a child fossil can help researchers understand how this enigmatic species developed, they are even more fascinated by how Leti ended up in the cave in the first place. The fragments of the childвЂ™s skull were found in an incredibly narrow passage of South AfricaвЂ™s Rising Star cave, where Homo naledi fossils were initially unearthed in 2013. The skull, from a child that was 4 to 6 years old at the time of death, is the first known to belong to Homo naledi. Meet Leti, the small child of an ancient human relative that lived between 236,000 and 335,000 years ago. One way to cut back on emissions? Converting classic cars, like a six-seat Rolls-Royce Phantom and James BondвЂ™s favorite Aston Martin DB5, into electric vehicles. Curtailing fossil fuels could limit long-term global warming. The gap is widening between the impacts of the climate crisis and the worldвЂ™s effort to adapt to them, according to a new United Nations report that will publish during the conference.ДЄ historic breakthrough was reached at the summit when 20 countries agreed to end financing for fossil fuel projects abroad in a deal announced Thursday. One mission that could help in this search is a large telescope, slated to launch in the 2040s and similar in scale to Hubble, that could seek signatures of life on about 25 potentially habitable exoplanets.ДЄs for our home planet, all eyes have been on the COP26 climate summit in Scotland as world leaders try to avert a global climate catastrophe. But astronomers need more information to find actual signs of habitability and life. There are over 4,000 known exoplanets across the galaxy, including the intriguing Earth-size planets of the Trappist system. Over the next decade, scientists will aim to unlock the secrets of the universe and identify Earth-like planets outside of our solar system to find other habitable worlds. ThatвЂ™s the consensus of the highly anticipated Astro2020 decadal survey published this week, which acts as a road map for agencies like NASA when planning their missions. ItвЂ™s time to find other planets like Earth and understand if weвЂ™re truly alone in the universe.

And perhaps space isnвЂ™t so alien after all. If our future really is out there, at least weвЂ™ll have a way to spice up our food. Space may seem cold, dark and alien, but itвЂ™s not as far removed from us as we may think.ДЄstronauts even hosted an out-of-this-world taco party on the International Space Station last week to celebrate and snack on the first chile peppers grown in space.
