Published Physicists solve durability issue in next-generation solar cells


Physicists jumped a major hurdle standing in the way of the commercialization of solar cells created with halide perovskites as a lower-cost, higher-efficiency replacement for silicon when generating electricity from the sun.
Published How to make hydrogen straight from seawater -- no desalination required


Researchers have developed a cheaper and more energy-efficient way to make hydrogen directly from seawater, in a critical step towards a truly viable green hydrogen industry. The new method splits the seawater directly into hydrogen and oxygen -- skipping the need for desalination and its associated cost, energy consumption and carbon emissions.
Published Four classes of planetary systems


Astronomers have long been aware that planetary systems are not necessarily structured like our solar system. Researchers have now shown that there are in fact four types of planetary systems.
Published Upsurge in rocket launches could impact the ozone layer


Researchers have summarized the threats that future rocket launches would pose to Earth's protective ozone layer.
Published Research reveals thermal instability of solar cells but offers a bright path forward


Researchers reveal the thermal instability that happens within the cells' interface layers, but also offers a path forward towards reliability and efficiency for halide perovskite solar technology.
Published Hubble captures the start of a new spoke season at Saturn


Since their discovery by NASA's Voyager mission in the 1980s, temporary 'spoke' features across Saturn's rings have fascinated scientists, yet eluded explanation. They have been observed in the years preceding and following the planet's equinox, becoming more prominent as the date approaches. Saturn's upcoming autumnal equinox of the northern hemisphere on May 6, 2025, means that spoke season has come again. NASA's Hubble Space Telescope will be on the job studying the spokes, thanks to time dedicated to Saturn in the mission's ongoing Outer Planet Atmospheres Legacy (OPAL) program. Are the smudgy features related to Saturn's magnetic field and its interaction with the solar wind, as prevailing theory suggests? Confirmation could come in this spoke season, as scientists combine archival data from NASA's Cassini mission with new Hubble observations.
Published Space dust as Earth's sun shield


Dust launched from the moon's surface or from a space station positioned between Earth and the sun could reduce enough solar radiation to mitigate the impacts of climate change.
Published 'Game-changing' findings for sustainable hydrogen production


Hydrogen fuel could be a more viable alternative to traditional fossil fuels, according to University of Surrey researchers who have found that a type of metal-free catalysts could contribute to the development of cost-effective and sustainable hydrogen production technologies.
Published Spanish lagoon used to better understand wet-to-dry transition of Mars


In the ongoing search for signs of life on Mars, a new study proposes focusing on 'time-resolved analogs' -- dynamic and similar Earth environments where changes can be analyzed over many years.
Published A new ring system discovered in our Solar System


Scientists have discovered a new ring system around a dwarf planet on the edge of the Solar System. The ring system orbits much further out than is typical for other ring systems, calling into question current theories of how ring systems are formed.
Published New models explain canyons on Pluto moon


In 2015, when NASA's New Horizons spacecraft encountered the Pluto-Charon system, scientists discovered interesting, geologically active objects instead of the inert icy orbs previously envisioned. Scientists have revisited the data to explore the source of cryovolcanic flows and an obvious belt of fractures on Pluto's large moon Charon. These new models suggest that when the moon's internal ocean froze, it may have formed the deep, elongated depressions along its girth but was less likely to lead to cryovolcanoes erupting with ice, water and other materials in its northern hemisphere.
Published Hubble directly measures mass of a lone white dwarf


Astronomers have directly measured the mass of a single, isolated white dwarf -- the surviving core of a burned-out, Sun-like star. Researchers found that the white dwarf is 56 percent the mass of our Sun. This agrees with earlier theoretical predictions of the white dwarf's mass and corroborates current theories of how white dwarfs evolve as the end product of a typical star's evolution. The unique observation yields insights into theories of the structure and composition of white dwarfs.
Published Passive radiative cooling can now be controlled electrically


Energy-efficient ways of cooling buildings and vehicles will be required in a changing climate. Researchers have now shown that electrical tuning of passive radiative cooling can be used to control temperatures of a material at ambient temperatures and air pressure.
Published Seawater split to produce 'green' hydrogen


Researchers have successfully split seawater without pre-treatment to produce green hydrogen.
Published Thin, lightweight layer provides radiation barrier for perovskites in space, protection from elements on Earth


An ultrathin protective coating proves sufficient to protect a perovskite solar cell from the harmful effects of space and harden it against environmental factors on Earth, according to newly published research.
Published Researchers complete first real-world study of Martian helicopter dust dynamics


Researchers have completed the first real-world study of Martian dust dynamics based on Ingenuity's historic first flights on the Red Planet, paving the way for future extraterrestrial rotorcraft missions. The work could support NASA's Mars Sample Return Program, which will retrieve samples collected by Perseverance, or the Dragonfly mission that will set course for Titan, Saturn's largest moon, in 2027.
Published Evidence that Saturn's moon Mimas is a stealth ocean world


When a scientist discovered surprising evidence that Saturn's smallest, innermost moon could generate the right amount of heat to support a liquid internal ocean, colleagues began studying Mimas' surface to understand how its interior may have evolved. Numerical simulations of the moon's Herschel impact basin, the most striking feature on its heavily cratered surface, determined that the basin's structure and the lack of tectonics on Mimas are compatible with a thinning ice shell and geologically young ocean.
Published Will machine learning help us find extraterrestrial life?


Researchers have applied a deep learning technique to a previously studied dataset of nearby stars and uncovered eight previously unidentified signals of interest.
Published Stability of perovskite solar cells reaches next milestone


Perovskite semiconductors promise highly efficient and low-cost solar cells. However, the semi-organic material is very sensitive to temperature differences, which can quickly lead to fatigue damage in normal outdoor use. Adding a dipolar polymer compound to the precursor perovskite solution helps to counteract this. The solar cells produced in this way achieve efficiencies of well above 24 %, which hardly drop under rapid temperature fluctuations between -60 and +80 Celsius over one hundred cycles. That corresponds to about one year of outdoor use.
Published Meteorites reveal likely origin of Earth's volatile chemicals


By analyzing meteorites, researchers have uncovered the likely far-flung origin of Earth's volatile chemicals, some of which form the building blocks of life.
