Published Extreme complexity in formation of rare earth mineral vital for tech industry
(via sciencedaily.com) Original source Researchers have unveiled that myriad, intricate factors influence the genesis and chemistry of bastnasite and rare earth carbonates, which are critically needed for today's tech industry and its hardware outputs. Their work unveils a newly acquired depth of understanding that had previously been unexplored in this field. In combination, the findings mark a significant advancement and promise to reshape our understanding of rare earth mineral formation.
Published Subduction zone splay faults compound hazards of great earthquakes
(via sciencedaily.com) Original source Groundbreaking research has provided new insight into the tectonic plate shifts that create some of the Earth's largest earthquakes and tsunamis.
Published Hubble views the dawn of a sun-like star
(via sciencedaily.com) Original source Looking like a glittering cosmic geode, a trio of dazzling stars blaze from the hollowed-out cavity of a reflection nebula in a new image from NASA's Hubble Space Telescope. The triple-star system is made up of the variable star HP Tau, HP Tau G2, and HP Tau G3. HP Tau is known as a T Tauri star, a type of young variable star that hasn't begun nuclear fusion yet but is beginning to evolve into a hydrogen-fueled star similar to our Sun.
Published Robotic 'SuperLimbs' could help moonwalkers recover from falls
(via sciencedaily.com) Original source SuperLimbs, a system of wearable robotic limbs, can physically support an astronaut and lift them back on their feet after a fall, helping them conserve energy for other essential tasks.
Published Detection of an Earth-sized exoplanet orbiting the ultracool dwarf star SPECULOOS-3
(via sciencedaily.com) Original source Astronomers have just discovered a new Earth-sized exoplanet around SPECULOOS-3, an 'ultracool dwarf' star as small as Jupiter, twice as cold as our Sun, and located 55 light-years from Earth. After the famous TRAPPIST-1, SPECULOOS 3 is the second planetary system discovered around this type of star.
Published WASP-193b, a giant planet with a density similar to that of cotton candy
(via sciencedaily.com) Original source Astronomers have just discovered WASP-193b, an extraordinarily low-density giant planet orbiting a distant Sun-like star.
Published Clues from deep magma reservoirs could improve volcanic eruption forecasts
(via sciencedaily.com) Original source New research into molten rock 20km below the Earth's surface could help save lives by improving the prediction of volcanic activity.
Published Squeezed by neighbors, planet glows with molten lava
(via sciencedaily.com) Original source Astrophysicists discovered that an exoplanet is covered with so many active volcanoes that seen from a distance it would take on a fiery, glowing-red hue.
Published Astrophysicists discover a novel method for hunting the first stars
(via sciencedaily.com) Original source A recent study has discovered a novel method for detecting the first-generations stars, known as Population III (Pop III) stars, which have never been directly detected. These potential discoveries about Pop III stars hold the promise of unlocking the secrets of the universe's origin and providing a deeper understanding of the remarkable journey from the primordial cosmos to the world we inhabit today.
Published Heavy snowfall and rain may contribute to some earthquakes
(via sciencedaily.com) Original source Episodes of heavy snowfall and rain likely contributed to a swarm of earthquakes over the past several years in northern Japan, researchers find. Their study shows climate conditions could initiate some earthquakes.
Published Possible atmosphere surrounding rocky exoplanet
(via sciencedaily.com) Original source Researchers may have detected atmospheric gases surrounding 55 Cancri e, a hot rocky exoplanet 41 light-years from Earth. This is the best evidence to date for the existence of any rocky planet atmosphere outside our solar system.
Published Rock steady: Study reveals new mechanism to explain how continents stabilized
(via sciencedaily.com) Original source Ancient, expansive tracts of continental crust called cratons have helped keep Earth's continents stable for billions of years, even as landmasses shift, mountains rise and oceans form. A new mechanism may explain how the cratons formed some 3 billion years ago, an enduring question in the study of Earth's history.
Published Ozone's influence on exoplanetary climate
(via sciencedaily.com) Original source In the quest for life beyond our solar system, a new study delves into the atmospheric dynamics of planet Proxima Centauri b, illuminating ozone's pivotal role in shaping planetary climates. This research signifies a significant leap forward in our understanding of habitable exoplanets.
Published Researchers show that slow-moving earthquakes are controlled by rock permeability
(via sciencedaily.com) Original source A research group explores how the makeup of rocks, specifically their permeability -- or how easily fluids can flow through them -- affects the frequency and intensity of slow slip events. Slow slips' role in the earthquake cycle may help lead to a better model to predict when earthquakes happen.
Published From fossils to fuel: Mozambique's Maniamba Basin's energy potential
(via sciencedaily.com) Original source In the ever-expanding search for energy resources, a new study has emerged from Mozambique's Maniamba Basin. Mozambique's Maniamba Basin could be a big source of natural gas.
Published Geologists, biologists unearth the atomic fingerprints of cancer
(via sciencedaily.com) Original source Earth scientists have long turned to minute differences in hydrogen atoms to explore the ancient history of our planet. A new study suggests that these same tiny atoms might also lead to new ways to track the growth of cancer.
Published Venus has almost no water: A new study may reveal why
(via sciencedaily.com) Original source Billions of years ago, Venus may have harbored as much water as Earth. Today, almost all of it has disappeared. A new study may help to explain why.
Published Hubble views a galaxy with a voracious black hole
(via sciencedaily.com) Original source Bright, starry spiral arms surround an active galactic center in a new NASA Hubble Space Telescope image of the galaxy NGC 4951. Located in the Virgo constellation, NGC 4951 is located roughly 50 million light-years away from Earth. It's classified as a Seyfert galaxy, which means that it's an extremely energetic type of galaxy with an active galactic nucleus (AGN).
Published New discoveries about Jupiter's magnetosphere
(via sciencedaily.com) Original source New discoveries about Jupiter could lead to a better understanding of Earth's own space environment and influence a long-running scientific debate about the solar system's largest planet.
Published Did a magnetic field collapse trigger the emergence of animals?
(via sciencedaily.com) Original source Researchers uncovered compelling evidence that Earth's magnetic field was in a highly unusual state when the macroscopic animals of the Ediacaran Period -- 635 to 541 million years ago -- diversified and thrived. Their study raises the question of whether these fluctuations in Earth's ancient magnetic field led to shifts in oxygen levels that may have been crucial to the proliferation of life forms millions of years ago.
