Published Our surprising magnetic galaxy
(via sciencedaily.com) Original source A team of astronomers has created the first-ever map of magnetic field structures within a spiral arm of our Milky Way galaxy. Previous studies on galactic magnetic fields only gave a very general picture, but the new study reveals that magnetic fields in the spiral arms of our galaxy break away from this general picture significantly and are tilted away from the galactic average by a high degree. The findings suggest magnetic fields strongly impact star-forming regions which means they played a part in the creation of our own solar system.
Published Surprise gamma-ray feature beyond our galaxy
(via sciencedaily.com) Original source Astronomers analyzing 13 years of data from NASA's Fermi Gamma-ray Space Telescope have found an unexpected and as yet unexplained feature outside of our galaxy.
Published Astronomers make rare exoplanet discovery, and a giant leap in detecting Earth-like bodies
(via sciencedaily.com) Original source Astronomers have made the rare discovery of a small, cold exoplanet and its massive outer companion -- shedding light on the formation of planets like Earth.
Published Generating stable qubits at room temperature
(via sciencedaily.com) Original source Quantum bits, or qubits, can revolutionize computing and sensing systems. However, cryogenic temperatures are required to ensure the stability of qubits. In a groundbreaking study, researchers observed stable molecular qubits of four electron spins at room temperature for the first time by suppressing the mobility of a dye molecule within a metal-organic framework. Their innovative molecular design opens doors to materials that could drive the development of quantum technologies capable of functioning in real-world conditions.
Published First direct imaging of small noble gas clusters at room temperature
(via sciencedaily.com) Original source Scientists have succeeded in the stabilization and direct imaging of small clusters of noble gas atoms at room temperature. This achievement opens up exciting possibilities for fundamental research in condensed matter physics and applications in quantum information technology. The key to this breakthrough was the confinement of noble gas atoms between two layers of graphene.
Published Observing macroscopic quantum effects in the dark
(via sciencedaily.com) Original source Be fast, avoid light, and roll through a curvy ramp: This is the recipe for a pioneering experiment proposed by theoretical physicists. An object evolving in a potential created through electrostatic or magnetic forces is expected to rapidly and reliably generate a macroscopic quantum superposition state.
Published NASA's Webb finds signs of possible aurorae on isolated brown dwarf
(via sciencedaily.com) Original source Astronomers have found a brown dwarf (an object more massive than Jupiter but smaller than a star) with infrared emission from methane, likely due to energy in its upper atmosphere. This is an unexpected discovery because the brown dwarf, W1935, is cold and lacks a host star; therefore, there is no obvious source for the upper atmosphere energy. The team speculates that the methane emission may be due to processes generating aurorae.
Published Unlocking the secrets of a 'Hot Saturn' and its spotted star
(via sciencedaily.com) Original source A team of astronomers has unraveled the enigmatic atmosphere of the exoplanet HAT-P-18 b, shedding light on its intriguing blend of gases, clouds, and even the effects of its star's activity.
Published 'Blob-like' home of farthest-known fast radio burst is collection of seven galaxies
(via sciencedaily.com) Original source In summer 2022, astronomers detected the most powerful and most distant fast radio burst (FRB) ever observed. Now, astronomers have pinpointed the extraordinary object's birthplace -- and it's rather curious, indeed. Using images from NASA's Hubble Space Telescope, the researchers traced the FRB back to not one galaxy but a group of at least seven galaxies.
Published Researchers demonstrate that quantum entanglement and topology are inextricably linked
(via sciencedaily.com) Original source Researchers have demonstrated the remarkable ability to perturb pairs of spatially separated yet interconnected quantum entangled particles without altering their shared properties.
Published Meteorite analysis shows Earth's building blocks contained water
(via sciencedaily.com) Original source Analysis of iron meteorites from the earliest years of the solar system indicate that the planetary 'seeds' that ultimately formed Earth contained water.
Published New study uses machine learning to bridge the reality gap in quantum devices
(via sciencedaily.com) Original source A study has used the power of machine learning to overcome a key challenge affecting quantum devices. For the first time, the findings reveal a way to close the 'reality gap': the difference between predicted and observed behavior from quantum devices.
Published Final supernova results from Dark Energy Survey offer unique insights into the expansion of the universe
(via sciencedaily.com) Original source In the culmination of a decade's worth of effort, scientists analyzed an unprecedented sample of more than 1,500 supernovae classified using machine learning. They placed the strongest constraints on the expansion of the universe ever obtained with the DES supernova survey. While consistent with the current standard cosmological model, the results do not rule out a more complex theory that the density of dark energy in the universe could have varied over time.
Published Three iron rings in a planet-forming disk
(via sciencedaily.com) Original source Astronomers have detected a three-ringed structure in the nursery of planets in the inner planet-forming disk of a young star. This configuration suggests two Jupiter-mass planets are forming in the gaps between the rings. The detailed analysis is consistent with abundant solid iron grains complementing the dust composition. As a result, the disk likely harbors metals and minerals akin to those in the Solar System's terrestrial planets. It offers a glimpse into conditions resembling the early Solar System over four billion years ago during the formation of rocky planets such as Mercury, Venus, and Earth.
Published Space oddity: Uncovering the origin of the universe's rare radio circles
(via sciencedaily.com) Original source Astronomers believe they may have found the origin of the universe's giant odd radio circles: they are shells formed by outflowing galactic winds, possibly from massive exploding stars known as supernovae.
Published Functional semiconductor made from graphene
(via sciencedaily.com) Original source Researchers have created the first functional semiconductor made from graphene, a single sheet of carbon atoms held together by the strongest bonds known. The breakthrough throws open the door to a new way of doing electronics.
Published Magnetic fields in the cosmos: Dark matter could help us discover their origin
(via sciencedaily.com) Original source We don't know how magnetic fields in the cosmos formed. Now a new theoretical research tells how the invisible part of our universe could help us find out, suggesting a primordial genesis, even within a second of the Big Bang.
