Scientists discover fluffy 'alien' planet where it rains sand
Scientists discover fluffy 'alien' planet where it rains sand
Experts have discovered a fluffy “alien” planet where it rains sand in stunning new observations from the James Webb Space Telescope. The bizarre-looking planet is officially known as exoplanet WASP-107b and has a cloud of silicate sand that exists high within its atmosphere giving it its strange fluffy appearance. NASA’s James Webb Space Telescope (JWST) has been responsible for some astounding findings since it was launched in 2021, including a mysterious galaxy shaped like a question mark. Now, observations made by the telescope have been used by experts who have been able to determine the atmospheric composition of the exoplanet that was pictured. A team of European astronomers found that water vapour, sulfur dioxide and silicate sand clouds existed in the exoplanet’s diverse atmosphere. The exoplanet WASP-107b is one of the lowest-density planets that astronomers are aware of. To put it into context, it is the same size as Jupiter, but has just 12 per cent of Jupiter’s mass. Thanks to its low density, it has allowed scientists to take a deeper look into the planet’s atmosphere, exploring 50 times deeper than would be possible with denser planets. The discovery of sulfur dioxide was a surprise because the host star it orbits only emits a small amount of high-energy light photons. But, its low-density atmosphere allows the photons to penetrate WASP-107b’s atmosphere where the chemical reaction that creates sulfur dioxide can occur. They also discovered that it essentially rains sand on the exoplanet due to the presence of clouds high in the atmosphere made up of fine silicate particles. Experts believe the clouds of sand form in the same way as rain does on Earth as the droplets continually fall and condense back into cloud form. The lead author of the study, Leen Decin from Katholieke Universiteit Leuven in Belgium, explained: “JWST is revolutionizing exoplanet characterisation, providing unprecedented insights at remarkable speed.” She added: “The discovery of clouds of sand, water, and sulfur dioxide on this fluffy exoplanet… is a pivotal milestone. It reshapes our understanding of planetary formation and evolution, shedding new light on our own solar system.” How to join the indy100's free WhatsApp channel Sign up to our free indy100 weekly newsletter Have your say in our news democracy.

'Lost City' deep in the Atlantic is like nothing else we've ever seen on Earth
'Lost City' deep in the Atlantic is like nothing else we've ever seen on Earth
The reality of what lies within our oceans has fascinated people since time immemorial, so it’s no wonder we’ve created countless myths about the watery depths. But step aside, Atlantis, scientists have discovered a real Lost City beneath the waves, and this one is teaming with life. The rocky, towering landscape is located west of the Mid-Atlantic Ridge mountain range, hundreds of metres below the surface of the Atlantic Ocean, and consists of massive walls, columns and monoliths stretching more than 60 metres (200ft) tall. To be clear, it’s not the home of some long-forgotten human civilisation, but that doesn’t make its existence any less significant. The hydrothermal field, dubbed the “Lost City” upon its discovery in the year 2000, is the longest-lived venting environment known in the ocean, Science Alert reports. Nothing else like it has ever been found on Earth, and experts think it could offer an insight into ecosystems that could exist elsewhere in the universe. For more than 120,000 years, snails, crustaceans and microbial communities have fed off the field’s vents, which spout out hydrogen, methane and other dissolved gases into the surrounding water. Despite the absence of oxygen down there, larger animals also survive in this extreme environment, including crabs, shrimps and eels. Although, they are, admittedly, rare. The hydrocarbons produced by its vents were not created by sunlight or carbon dioxide, but by chemical reactions way down on the seafloor. This is how life on our planet may have originated some 3.7 billion years, and how it could be formed on others. "This is an example of a type of ecosystem that could be active on Enceladus or Europa right this second," microbiologist William Brazelton told The Smithsonian back in 2018, referring to the moons of Saturn and Jupiter respectively. "And maybe Mars in the past." The tallest of the Lost City’s monoliths has been named Poseidon, after the Greek god of the sea, and it measures more than 60 metres high. Meanwhile, just northeast of the tower, is a cliffside where the vents “weep” with fluid, producing "clusters of delicate, multi-pronged carbonate growths that extend outward like the fingers of upturned hands", according to researchers at the University of Washington. There are now calls for the Lost City to be listed as a World Heritage site to protect the natural phenomenon, particularly given humans’ propensity to destroy precious ecosystems. Back in 2018, it was confirmed that Poland had won the rights to mine the deep sea around the thermal field. And whilst, in theory, the Lost City would not be touched by such works, as Science Alert notes, the destruction of its surroundings could have unintended consequences.
