Published Astronomers uncover risks to planets that could host life
(via sciencedaily.com) Original source A groundbreaking study has revealed that red dwarf stars can produce stellar flares that carry far-ultraviolet (far-UV) radiation levels much higher than previously believed.
Published Scientists pin down the origins of the moon's tenuous atmosphere
(via sciencedaily.com) Original source Scientists say they have identified the main process that formed the moon's atmosphere and continues to sustain it today. The team reports that the lunar atmosphere is primarily a product of 'impact vaporization.'
Published Key to rapid planet formation
(via sciencedaily.com) Original source Researchers have developed a new model to explain the formation of giant planets such as Jupiter, which furnishes deeper insights into the processes of planet formation and could expand our understanding of planetary systems.
Published Scientists devise method to secure Earth's biodiversity on the moon
(via sciencedaily.com) Original source New research led proposes a plan to safeguard Earth's imperiled biodiversity by cryogenically preserving biological material on the moon. The moon's permanently shadowed craters are cold enough for cryogenic preservation without the need for electricity or liquid nitrogen.
Published The rotation of a nearby star stuns astronomers
(via sciencedaily.com) Original source Astronomers have found that the rotational profile of a nearby star, V889 Herculis, differs considerably from that of the Sun. The observation provides insights into the fundamental stellar astrophysics and helps us understand the activity of the Sun, its spot structures and eruptions.
Published The corona is weirdly hot: Parker Solar Probe rules out one explanation
(via sciencedaily.com) Original source By diving into the sun's corona, NASA's Parker Solar Probe has ruled out S-shaped bends in the sun's magnetic field as a cause of the corona's searing temperatures.
Published California a botanical and climate change hot spot
(via sciencedaily.com) Original source Climate-driven shifts in California's biodiversity call for innovation and continued environmental stewardfship, says a new study. California's 30x30 Initiative and efforts to harmonize biodiversity with renewable energy are promising steps, while wildfire strategies need to further adapt.
Published Solar absorption by black carbon in fire clouds quantified
(via sciencedaily.com) Original source Aerosol scientists quantify the extent of light absorption by black carbon in fire clouds to better model climate impacts of extreme wildfire events.
Published Space-trekking muscle tests drugs for microgravity-induced muscle impairment
(via sciencedaily.com) Original source A gentle rumble ran under a researcher's feet as a rocket carrying her research -- live, human muscle cells grown on scaffolds fixed on tiny chips -- lifted off, climbed, and disappeared into the sky to the International Space Station National Laboratory. These chips would help her better understand muscle impairment, often seen in astronauts and older adults, and test drugs to counter the condition.
Published Images of nearest 'super-Jupiter' open a new window to exoplanet research
(via sciencedaily.com) Original source Using the James Webb Space Telescope (JWST), astronomers imaged a new exoplanet that orbits a star in the nearby triple system Epsilon Indi. The planet is a cold super-Jupiter exhibiting a temperature of around 0 degrees Celsius and a wide orbit comparable to that of Neptune around the Sun. This measurement was only possible thanks to JWST's unprecedented imaging capabilities in the thermal infrared. It exemplifies the potential of finding many more such planets similar to Jupiter in mass, temperature, and orbit. Studying them will improve our knowledge of how gas giants form and evolve in time.
Published Researchers warn of unprecedented arsenic release from wildfires
(via sciencedaily.com) Original source The wildfire season of 2023 was the most destructive ever recorded in Canada and a new study suggests the impact was unprecedented. It found that four of the year's wildfires in mine-impacted areas around Yellowknife, Northwest Territories potentially contributed up to half of the arsenic that wildfires emit globally each year.
Published Expiring medications could pose challenge on long space missions
(via sciencedaily.com) Original source A new study shows that over half of the medicines stocked in space -- staples such as pain relievers, antibiotics, allergy medicines, and sleep aids -- would expire before astronauts could return to Earth.
Published Researchers explore the effects of stellar magnetism on potential habitability of exoplanets
(via sciencedaily.com) Original source A study extends the definition of a habitable zone for planets to include their star's magnetic field.
Published Researchers enhance tool to better predict where and when wildfires will occur
(via sciencedaily.com) Original source A newly enhanced database is expected to help wildfire managers and scientists better predict where and when wildfires may occur by incorporating hundreds of additional factors that impact the ignition and spread of fire.
Published Astrophysicists uncover supermassive blackhole/dark matter connection in solving the 'final parsec problem'
(via sciencedaily.com) Original source Researchers have found a link between some of the largest and smallest objects in the cosmos: supermassive black holes and dark matter particles. Their new calculations reveal that pairs of supermassive black holes (SMBHs) can merge into a single larger black hole because of previously overlooked behavior of dark matter particles, proposing a solution to the longstanding 'final parsec problem' in astronomy.
Published Scientists use AI to predict a wildfire's next move
(via sciencedaily.com) Original source Researchers have developed a new model that combines generative AI and satellite data to accurately forecast wildfire spread.
Published Life signs could survive near surfaces of Enceladus and Europa
(via sciencedaily.com) Original source Europa and Enceladus, icy moons of Jupiter and Saturn respectively, have evidence of oceans beneath their crusts. A NASA experiment suggests -- if these oceans support life -- signatures of that life in the form of organic molecules (like amino acids and nucleic acids) could survive just under the surface ice despite the harsh, ionizing radiation on these worlds. If robotic landers were to go to these moons to look for life signs, they would not have to dig very deep to find amino acids that have survived being altered or destroyed by radiation.
Published Early riser! The Sun is already starting its next solar cycle -- despite being halfway through its current one
(via sciencedaily.com) Original source The first rumblings of the Sun's next 11-year solar cycle have been detected in sound waves inside our home star -- even though it is only halfway through its current one. This existing cycle is now at its peak, or 'solar maximum' -- which is when the Sun's magnetic field flips and its poles swap places -- until mid-2025.
Published New dawn for space storm alerts could help shield Earth's tech
(via sciencedaily.com) Original source Space storms could soon be forecasted with greater accuracy than ever before thanks to a big leap forward in our understanding of exactly when a violent solar eruption may hit Earth. Scientists say it is now possible to predict the precise speed a coronal mass ejection (CME) is travelling at and when it will smash into our planet -- even before it has fully erupted from the Sun.
Published Exoplanet-hunting telescope to begin search for another Earth in 2026
(via sciencedaily.com) Original source Europe's next big space mission -- a telescope that will hunt for Earth-like rocky planets outside of our solar system -- is on course to launch at the end of 2026. PLATO, or PLAnetary Transits and Oscillations of stars, is being built to find nearby potentially habitable worlds around Sun-like stars that we can examine in detail.
