Published Three iron rings in a planet-forming disk



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



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 High-performance stretchable solar cells



Engineers have succeeded in implementing a stretchable organic solar cell by applying a newly developed polymer material that demonstrated the world's highest photovoltaic conversion efficiency (19%) while functioning even when stretched for more than 40% of its original state. This new conductive polymer has high photovoltaic properties that can be stretched like rubber. The newly developed polymer is expected to play a role as a power source for next-generation wearable electronic devices.
Published Conflict in full swing: Forest bats avoid large areas around fast-moving wind turbines



Not only do many bats die at wind turbines, the turbines also displace some species from their habitats over large areas. When the turbines are in operation at relatively high wind speeds, the activity of bat species that hunt in structurally dense habitats such as forests drops by almost 80 per cent within a radius of 80 to 450 meters around the turbine.
Published Magnetic fields in the cosmos: Dark matter could help us discover their origin



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.
Published Nature-inspired advanced materials achieves 99.6% solar reflectivity



Scientific researchers draw inspiration from nature's brilliance as they seek to develop transformative solutions to unresolved challenges.
Published A carbon-lite atmosphere could be a sign of water and life on other terrestrial planets



Best chance of finding liquid water, and even life on other planets, is to look for the absence of carbon dioxide in their atmospheres.
Published Further evidence for quark-matter cores in massive neutron stars



New theoretical analysis places the likelihood of massive neutron stars hiding cores of deconfined quark matter between 80 and 90 percent. The result was reached through massive supercomputer runs utilizing Bayesian statistical inference.
Published Hubble sights a galaxy with 'forbidden' light



A whirling image features a bright spiral galaxy known as MCG-01-24-014, which is located about 275 million light-years from Earth. In addition to being a well-defined spiral galaxy, MCG-01-24-014 has an extremely energetic core known as an active galactic nucleus (AGN) and is categorized as a Type-2 Seyfert galaxy. Seyfert galaxies, along with quasars, host one of the most common subclasses of AGN. While the precise categorization of AGNs is nuanced, Seyfert galaxies tend to be relatively nearby and their central AGN does not outshine its host, while quasars are very distant AGNs with incredible luminosities that outshine their host galaxies.
Published Researchers study a million galaxies to find out how the universe began



Researchers have analyzed more than one million galaxies to explore primordial fluctuations that seeded the formation of the structure of the entire universe.
Published New material allows for better hydrogen-based batteries and fuel cells



Researchers have developed a solid electrolyte for transporting hydride ions at room temperature. This breakthrough means that the full advantages of hydrogen-based solid-state batteries and fuel cells can be had without the need for constant hydration. This will reduce their complexity and cost, which is essential for advancing towards a practical hydrogen-based energy economy.
Published Astronomers detect seismic ripples in ancient galactic disk



A new snapshot of an ancient, far-off galaxy could help scientists understand how it formed and the origins of our own Milky Way. At more than 12 billion years old, BRI 1335-0417 is the oldest and furthest known spiral galaxy in our universe. The researchers were able to not only capture the motion of the gas around BRI 1335-0417, but also reveal a seismic wave forming -- a first in this type of early galaxy.
Published New 1.5-billion-pixel image shows Running Chicken Nebula in unprecedented detail



While many holiday traditions involve feasts of turkey, soba noodles, latkes or Pan de Pascua, this year, the European Southern Observatory is bringing you a holiday chicken. The so-called Running Chicken Nebula, home to young stars in the making, is revealed in spectacular detail in this 1.5-billion-pixel image captured by the VLT Survey Telescope.
Published Supernova encore: Second lensed supernova in a distant galaxy



In November 2023, NASA's James Webb Space Telescope observed a massive cluster of galaxies named MACS J0138.0-2155. Through an effect called gravitational lensing, first predicted by Albert Einstein, a distant galaxy named MRG-M0138 appears warped by the powerful gravity of the intervening galaxy cluster. In addition to warping and magnifying the distant galaxy, the gravitational lensing effect caused by MACS J0138 produces five different images of MRG-M0138.
Published Pancake stack of films on a balloon most accurate gamma-ray telescope



A pancake stack of radioactivity-sensitive films carried through the sky by a balloon was able to take the world's most accurate picture of a neutron star's gamma ray beam. To achieve this, researchers combined the oldest method of capturing radioactive radiation with the newest data capturing techniques and a clever time-recording device.
Published Cosmic lights in the forest



Supercomputer helped astronomers develop PRIYA, the largest suite of hydrodynamic simulations yet made of large-scale structure in the universe.
Published Filming the microscopic flow of hydrogen atoms in a metal



Using conventional X-rays and lasers to detect the atomic state of hydrogen is challenging, given its small size. A group of researchers may have overcome this barrier by unveiling a new visualization technique that employs an optical microscope and polyaniline to paint a better picture of how hydrogen behaves in metals.
Published Scientists measure the distance to stars by their music



A team of astronomers has used asteroseismology, or the study of stellar oscillations, to accurately measure the distance of stars from the Earth. Their research examined thousands of stars and checked the measurements taken during the Gaia mission to study the near Universe.
Published New red galaxies turn out to be already known blue galaxies



Not all discoveries turn out to be actual new discoveries. This was the case for the extremely red objects (EROs) found in James Webb Space Telescope (JWST) data. Analysis shows that they are very similar to blue-excess dust obscured galaxies (BluDOGs) already reported in Subaru Telescope data.
Published Astronomers discover first population of binary stripped stars



Astronomers have discovered a population of massive stars that have been stripped of their hydrogen envelopes by their companions in binary systems. The findings shed light on the hot helium stars that are believed to be the origins of hydrogen-poor core-collapse supernovae and neutron star mergers.
