Scientists are optimistic about the possibility of finding life on other planets. Nasa's James Webb Space Telescope (JWST) found a possible sign of a gas that, on Earth, is produced by simple marine organisms. It was detected this month in the atmosphere of a planet named K2-18b, which is 120 light years away. The planet is in what astronomers call ''the Goldilocks zone' - the right distance away from its star for the surface temperature to be neither too hot nor too cold, but just right for there to be liquid water, which is essential to support life. The team expects to know in a year's time whether the hints are confirmed or have gone away. "We live in an infinite Universe, with infinite stars and planets. And it's been obvious to many of us that we can't be the only intelligent life out there," Prof Catherine Heymans, Scotland's Astronomer Royal told the BBC. "We now have the technology and the capability to answer the question of whether we are alone in the cosmos." Prof Nikku Madhusudhan of the Institute of Astronomy at Cambridge University, who led the study, told the BBC that if the hints are confirmed "it would radically change the way we think about the search for life". "If we find signs of life on the very first planet we study, it will raise the possibility that life is common in the Universe." He predicted that within five years there will be "a major transformation" in our understanding of life in the Universe. If his team don't find life signs on K2-18b, they have 10 more Goldilocks planets on their list to study - and possibly many more after that. Even finding nothing would "provide important insights into the possibility of life on such planets", he said. Meanwhile there are other separate projects all looking for signs of life in the universe. Pretty exciting. Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

The name “core” suggests something hard and fixed but, it turns out, the Earth’s core is leaking. That is, at least, according to a team of top scientists, who drew the conclusion after analysing 62-million-old Arctic rocks. Geochemists from the California Institute of Technology and Woods Hole Oceanographic Institution detected record concentrations of helium 3 (3He) and helium 4 (4He) isotopes in the rocks, which suggest a slow trickle up from the very heart of our planet. They believe there could be reserves of the elusive gas buried some 2,900km underground. Helium is a surprisingly rare element on the Earth’s surface and experts have yet to establish just how much of it remains trapped deep beneath our feet. However, the new discovery has provided them with a fresh insight into the most mysterious region of our world. Understanding the presence of these helium isotopes could illuminate key processes in the core, such as how the Earth generated its life-protecting magnetic field. Most helium in the universe dates back to the Big Bang which occurred 13.8 billion years ago. The Earth swallowed up some of this as an infant planet, but mostly burped it all away during its 4.6 billion-year-long formation, as Science Alert reports. This means that any traces of helium found in volcanic rock – such as the samples unearthed in the Arctic – are believed to come either from pockets of mantle that are yet to release their helium, or from a vast, slow-leaking reserve. Basaltic lavas on Canada's Baffin Island contain some of the world's highest ratios of 3He to 4He, which geologists believe indicates that the gas's presence is not to do with the atmosphere, but rather the sign of deeper terrestrial origins. Several years ago, geochemist Forrest Horton uncovered helium isotope ratios of up to 50 times that of atmospheric levels in samples collected from Baffin's lava fields. This unusual concentration was also detected in lavas collected from Iceland. Horton and his team wondered if the helium in both samples may have derived from an ancient reservoir deep within the crust. And, it seems, their hunch may have been right. Their latest analysis – including specimens of the mineral olivine taken from dozens of sites across Baffin and surrounding islands – has delivered the highest ratio of 3He to 4He ever recorded in volcanic rock – measuring nearly 70 times anything previously detected in the atmosphere, as Science Alert notes. The team also considered ratios of other isotopes in order to rule out factors that may have altered the helium’s composition post-volcanic eruption, and found that the ratio of isotopes in the gas neon also matched the conditions present during the Earth’s formation. Despite advances in geology, the Earth’s core remains a great mystery, given that we have no way of directly exploring its core. The deepest hole humans have ever dug – branded the "entrance to hell" – extended an impressive 12,263m (40,230ft) down, but even that doesn’t come close to breaking through the crust to the layers beneath. Still, thanks to techniques like seismic tomography – which analyses how waves of energy travel through different materials during earthquakes – we’ve been able to map out the world’s interior. And carefully crafted simulations, based on the thermodynamics and pressures of our planet’s innards, suggest reserves of noble gases (like helium and neon) trapped in the core could have been protected as the Earth grew before seeping into the surrounding mantle over time. If the core is leaking, this could teach us a thing or two about how planets like ours form and how life, eventually, emerges.
