Published The metalens meets the stars
(via sciencedaily.com) Original source Researchers have developed a 10-centimeter-diameter glass metalens that can image the sun, the moon and distant nebulae with high resolution. It is the first all-glass, large-scale metalens in the visible wavelength that can be mass produced using conventional CMOS fabrication technology.
Published Study delivers detailed photos of galaxies' inner structures
(via sciencedaily.com) Original source High-resolution images captured by the James Webb Space Telescope are offering powerful insights into the complex dust patterns of nearby star-forming galaxies.
Published Astronomers produce most sensitive radio image ever of ancient star cluster
(via sciencedaily.com) Original source Astronomers have created the most sensitive radio image ever of a globular cluster, an ancient ball of tightly-packed stars.
Published 'Smart glove' can boost hand mobility of stroke patients
(via sciencedaily.com) Original source This month, a group of stroke survivors in British Columbia will test a new technology designed to aid their recovery, and ultimately restore use of their limbs and hands. Participants will wear a new groundbreaking 'smart glove' capable of tracking their hand and finger movements during rehabilitation exercises.
Published Earth-sized planet discovered in 'our solar backyard'
(via sciencedaily.com) Original source Astronomers have discovered a planet closer and younger than any other Earth-sized world yet identified. It's a remarkably hot world whose proximity to our own planet and to a star like our sun mark it as a unique opportunity to study how planets evolve.
Published NASA scientists discover a novel galactic 'fossil'
(via sciencedaily.com) Original source Researchers at NASA's Goddard Space Flight Center have discovered X-ray activity that sheds light on the evolution of galaxies.
Published Close encounters of the supermassive black hole kind
(via sciencedaily.com) Original source Astrophysicists have confirmed the accuracy of an analytical model that can unlock key information about supermassive black holes and the stars they engulf.
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 Potential solvents identified for building on moon and Mars
(via sciencedaily.com) Original source Researchers have taken the first steps toward finding liquid solvents that may someday help extract critical building materials from lunar and Martian-rock dust, an important piece in making long-term space travel possible. Using machine learning and computational modeling, researchers have found about half a dozen good candidates for solvents that can extract materials on the moon and Mars usable in 3D printing. The powerful solvents, called ionic liquids, are salts that are in a liquid state.
Published NASA's Webb discovers dusty 'cat's tail' in Beta Pictoris System
(via sciencedaily.com) Original source Beta Pictoris, a young planetary system located just 63 light-years away, continues to intrigue scientists even after decades of in-depth study. It possesses the first dust disk imaged around another star -- a disk of debris produced by collisions between asteroids, comets, and planetesimals. Observations from NASA's Hubble Space Telescope revealed a second debris disk in this system, inclined with respect to the outer disk, which was seen first. Now, a team of astronomers using NASA's James Webb Space Telescope to image the Beta Pictoris system (Beta Pic) has discovered a new, previously unseen structure.
Published Artificial intelligence helps unlock advances in wireless communications
(via sciencedaily.com) Original source A new wave of communication technology is quickly approaching and researchers are now investigating ways to configure next-generation mobile networks.
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 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.
