Published Exoplanets true to size
(via sciencedaily.com) Original source A star's magnetic field must be considered in order to correctly determine the characteristics of exoplanets from observations by space telescopes such as Kepler, James Webb, or PLATO. Researchers show that the distribution of the star's brightness over its disk depends on the star's level of magnetic activity. This, in turn, affects the signature of an exoplanet in observational data. The new model must be used in order to properly interpret the data from the latest generation of space telescopes pointed at distant worlds outside our Solar System.
Published Breakthrough promises secure quantum computing at home
(via sciencedaily.com) Original source The full power of next-generation quantum computing could soon be harnessed by millions of individuals and companies, thanks to a breakthrough guaranteeing security and privacy. This advance promises to unlock the transformative potential of cloud-based quantum computing.
Published The hidden role of the Milky Way in ancient Egyptian mythology
(via sciencedaily.com) Original source Astrophysicists shed light on the relationship between the Milky Way and the Egyptian sky-goddess Nut. The paper draws on ancient Egyptian texts and simulations to argue that the Milky Way might have shone a spotlight, as it were, on Nut's role as the sky. It proposes that in winter, the Milky Way highlighted Nut's outstretched arms, while in summer, it traced her backbone across the heavens.
Published Study shedding new light on Earth's global carbon cycle could help assess liveability of other planets
(via sciencedaily.com) Original source Research has uncovered important new insights into the evolution of oxygen, carbon, and other vital elements over the entire history of Earth -- and it could help assess which other planets can develop life, ranging from plants to animals and humans.
Published Protecting art and passwords with biochemistry
(via sciencedaily.com) Original source A new molecular test method helps to prove the authenticity of works of art. The new method could also help to make passwords secure against quantum computers.
Published How the moon turned itself inside out
(via sciencedaily.com) Original source Linking analyses of the moon's gravity field with models of its earliest evolution, scientists tell a story of the moon turning itself inside out after it solidified from a primordial magma ocean. The process left behind a vestige of dense, titanium-rich material beneath its Earth-facing side that makes its presence known by gravity anomalies.
Published Climate change threatens Antarctic meteorites
(via sciencedaily.com) Original source Antarctica harbors a large concentration of meteorites imbuing the icy continent with an unparalleled wealth of information on our solar system. However, these precious meteorites are rapidly disappearing from the ice sheet surface due to global warming, according to a new study.
Published Neutron stars are key to understanding elusive dark matter
(via sciencedaily.com) Original source Scientists may be one step closer to unlocking one of the great mysteries of the universe after calculating that neutron stars might hold a key to helping us understand elusive dark matter.
Published CHEOPS detects a 'rainbow' on an exoplanet
(via sciencedaily.com) Original source The CHEOPS space telescope is providing new information on the mysterious exoplanet WASP-76b. This ultra-hot giant is characterized by an asymmetry between the amount of light observed on its eastern terminator -- the fictitious line that separates its night side from its day side -- and that observed on its western terminator. This peculiarity is thought to be due to a 'glory', a luminous phenomenon similar to a rainbow, which occurs if the light from the star -- the 'sun' around which the exoplanet orbits -- is reflected by clouds made up of a perfectly uniform substance. If this hypothesis is confirmed, this would be the first detection of this phenomenon outside our solar system.
Published 100 kilometers of quantum-encrypted transfer
(via sciencedaily.com) Original source Researchers have taken a big step towards securing information against hacking. They have succeeded in using quantum encryption to securely transfer information 100 kilometers via fiber optic cable -- roughly equivalent to the distance between Oxford and London.
Published Unlocking supernova stardust secrets
(via sciencedaily.com) Original source New research has discovered a rare dust particle trapped in an ancient extra-terrestrial meteorite that was formed by a star other than our sun.
Published Long-period oscillations control the Sun's differential rotation
(via sciencedaily.com) Original source The interior of the Sun does not rotate at the same rate at all latitudes. The physical origin of this differential rotation is not fully understood. It turns out, long-period solar oscillations discovered in 2021 play a crucial role in controlling the Sun's rotational pattern. The long-period oscillations are analogous to the baroclinically unstable waves in Earth's atmosphere that shape the weather. In the Sun, these oscillations carry heat from the slightly hotter poles to the slightly cooler equator.
Published Distant 'space snowman' unlocks mystery of how some dormant deep space objects become 'ice bombs'
(via sciencedaily.com) Original source Researchers found that the double-lobed object, which is officially named Kuiper Belt Object 486958 Arrokoth and resembles a snowman, may have ancient ices stored deep within it from when the object first formed billions of years ago.
Published Turbulence within solar transients imaged
(via sciencedaily.com) Original source Scientists captured images showing the development of turbulence as a Coronal Mass Ejection (CME) interacted with the ambient solar wind in the circumsolar space.
Published Tiniest 'starquake' ever detected
(via sciencedaily.com) Original source An orange dwarf star has yielded the tiniest 'starquakes' ever recorded, measured by an international team of scientists.
Published Scientists on the hunt for evidence of quantum gravity's existence at the South Pole
(via sciencedaily.com) Original source An Antarctic large-scale experiment is striving to find out if gravity also exists at the quantum level. An extraordinary particle able to travel undisturbed through space seems to hold the answer.
Published James Webb Space Telescope captures the end of planet formation
(via sciencedaily.com) Original source How much time do planets have to form from a swirling disk of gas and dust around a star? A new study gives scientists a better idea of how our own solar system came to be.
Published Signs of life would be detectable in single ice grain emitted from extraterrestrial moons
(via sciencedaily.com) Original source Could life be found in frozen sea spray from moons orbiting Saturn or Jupiter? New research finds that life can be detected in a single ice grain containing one bacterial cell or portions of a cell. The results suggest that if life similar to that on Earth exists on these planetary bodies, that this life should be detectable by instruments launching in the fall.
Published Secrets of the Van Allen belt revealed in new study
(via sciencedaily.com) Original source A challenge to space scientists to better understand our hazardous near-Earth space environment has been set in a new study.
Published Icy impacts: Planetary scientists use physics and images of impact craters to gauge the thickness of ice on Europa
(via sciencedaily.com) Original source New study reveals that Europa's ice shell is at least 20 kilometers thick.
