Published Does this exoplanet have a sibling sharing the same orbit?
(via sciencedaily.com) Astronomers have found the possible 'sibling' of a planet orbiting a distant star. The team has detected a cloud of debris that might be sharing this planet's orbit and which, they believe, could be the building blocks of a new planet or the remnants of one already formed. If confirmed, this discovery would be the strongest evidence yet that two exoplanets can share one orbit.
Published The puzzle of the galaxy with no dark matter
(via sciencedaily.com) New research has found the first evidence of a massive galaxy with no dark matter. The result is a challenge to the current standard model of cosmology.
Published Current thinking on batteries overturned by cathode oxidation research
(via sciencedaily.com) Scientists have made a significant breakthrough in understanding and overcoming the challenges associated with Ni-rich cathode materials used in lithium-ion batteries.
Published Unusual white dwarf star is made of hydrogen on one side and helium on the other
(via sciencedaily.com) Original source In a first for white dwarfs, the burnt-out cores of dead stars, astronomers have discovered that at least one member of this cosmic family is two faced. One side of the white dwarf is composed of hydrogen, while the other is made up of helium.
Published VERA unveils surroundings of rapidly growing black holes
(via sciencedaily.com) Astronomers used the state-of-the-art capability of VERA, a Japanese network of radio telescopes, to uncover valuable clues about how rapidly growing 'young' supermassive black holes form, grow, and possibly evolve into more powerful quasars.
Published Dry manufacturing process offers path to cleaner, more affordable high-energy EV batteries
(via sciencedaily.com) Early experiments have revealed significant benefits to a dry battery manufacturing process. This eliminates the use of toxic solvents while showing promise for delivering a battery that is durable, less weighed down by inactive elements and able to maintain high energy storage capacity after use. Such improvements could boost wider EV adoption, helping to reduce carbon emissions and achieve U.S. climate goals.
Published Astronomers discover striking evidence of 'unusual' stellar evolution
(via sciencedaily.com) Astronomers have found evidence that some stars boast unexpectedly strong surface magnetic fields, a discovery that challenges current models of how they evolve.
Published Hubble views a galactic monster
(via sciencedaily.com) The NASA/ESA Hubble Space Telescope has captured a monster in the making in this observation of the exceptional galaxy cluster eMACS J1353.7+4329, which lies about eight billion light-years from Earth in the constellation Canes Venatici. This collection of at least two galaxy clusters is in the process of merging together to create a cosmic monster, a single gargantuan cluster acting as a gravitational lens.
Published Stellar cradles and graves seen in farthest galaxy ever
(via sciencedaily.com) Original source New observations have distinguished the sites of star formation and a possible site of star death from the surrounding nebula in a galaxy 13.2 billion light-years away. This is the farthest that such structures have been observed.
Published Astronomers identify the coldest star yet that emits radio waves
(via sciencedaily.com) Original source Brown dwarf stars rarely emit radio waves. Here scientists have found the coldest star yet emitting at these long wave lengths. Understanding the science of 'ultracool brown dwarfs' will help deepen our knowledge of how stars evolve.
Published James Webb Telescope catches glimpse of possible first-ever 'dark stars'
(via sciencedaily.com) Three bright objects initially identified as galaxies in observations from the James Webb Space Telescope might actually represent an exotic new form of star. If confirmed, the discovery would also shed light on the nature of dark matter.
Published Rare, double-lobe nebula resembles overflowing cosmic 'jug'
(via sciencedaily.com) Original source A billowing pair of nearly symmetrical loops of dust and gas mark the death throes of an ancient red-giant star. The resulting structure, said to resemble an old style of English jug, is a rarely seen bipolar reflection nebula. Evidence suggests that this object formed by the interactions between the dying red giant and a now-shredded companion star.
Published When the stars align: Astronomers find answers to mysterious action of ghost stars in our Galaxy
(via sciencedaily.com) Original source Scientists have found a source for the mysterious alignment of stars near the Galactic Center.
Published Search for dark matter
(via sciencedaily.com) Original source Scientists have applied a promising new method to search for dark matter particles in a particle accelerator. The method is based on the observation of the spin polarization of a particle beam in a storage ring COSY.
Published Webb celebrates first year of science with close-up on birth of sun-like stars
(via sciencedaily.com) Original source From our cosmic backyard in the solar system to distant galaxies near the dawn of time, NASA's James Webb Space Telescope has delivered on its promise of revealing the universe like never before in its first year of science operations. To celebrate the completion of a successful first year, NASA has released Webb's image of a small star-forming region in the Rho Ophiuchi cloud complex.
Published Reinventing cosmology: New research puts age of universe at 26.7 -- not 13.7 -- billion years
(via sciencedaily.com) Original source Our universe could be twice as old as current estimates, according to a new study that challenges the dominant cosmological model and sheds new light on the so-called 'impossible early galaxy problem.'
Published Record-breaking team of citizen scientists contribute data on pinwheel galaxy supernova
(via sciencedaily.com) Original source Citizen scientists have set a new record for the SETI Institute and Unistellar, comprising the highest number of observers providing data on a single event. Amateur astronomers conducted a groundbreaking observation of supernova (SN) 2023ixf. The observations, which began just one hour after the supernova's first known appearance, have generated the longest continuous light curve of this supernova gathered by citizen scientists.
Published Next-generation flow battery design sets records
(via sciencedaily.com) A new flow battery design achieves long life and capacity for grid energy storage from renewable fuels.
Published New design rule for high-entropy superionic solid-state conductors
(via sciencedaily.com) Solid electrolytes with high lithium-ion conductivity can be designed for millimeter-thick battery electrodes by increasing the complexity of their composite superionic crystals, report researchers from Tokyo Tech. This new design rule enables the synthesis of high-entropy active materials while preserving their superionic conduction.
Published Webb Telescope detects most distant active supermassive black hole
(via sciencedaily.com) Original source Researchers have discovered the most distant active supermassive black hole to date with the James Webb Space Telescope (JWST). The galaxy, CEERS 1019, existed about 570 million years after the big bang, and its black hole is less massive than any other yet identified in the early universe.
