Metal scar found on cannibal star      (via sciencedaily.com)     Original source 

When a star like our Sun reaches the end of its life, it can ingest the surrounding planets and asteroids that were born with it. Now, researchers have found a unique signature of this process for the first time -- a scar imprinted on the surface of a white dwarf star.

Webb finds evidence for neutron star at heart of young supernova remnant      (via sciencedaily.com)     Original source 

NASA's James Webb Space Telescope has found the best evidence yet for emission from a neutron star at the site of a recently observed supernova. The supernova, known as SN 1987A, was a core-collapse supernova, meaning the compacted remains at its core formed either a neutron star or a black hole. Evidence for such a compact object has long been sought, and while indirect evidence for the presence of a neutron star has previously been found, this is the first time that the effects of high-energy emission from the probable young neutron star have been detected.

Brightest and fastest-growing: Astronomers identify record-breaking quasar      (via sciencedaily.com)     Original source 

Astronomers have characterized a bright quasar, finding it to be not only the brightest of its kind, but also the most luminous object ever observed. Quasars are the bright cores of distant galaxies and they are powered by supermassive black holes. The black hole in this record-breaking quasar is growing in mass by the equivalent of one Sun per day, making it the fastest-growing black hole to date.

Three years later, search for life on Mars continues      (via sciencedaily.com)     Original source 

Scientists suspect Mars once had long-lived rivers, lakes and streams. Today, water on Mars is found in ice at the poles and trapped below the Martian surface. Researchers now reveal that Mars also may have had hydrothermal systems based on the hydrated magnesium sulfate the rover identified in the volcanic rocks.

Method identified to double computer processing speeds      (via sciencedaily.com)     Original source 

Scientists introduce what they call 'simultaneous and heterogeneous multithreading' or SHMT. This system doubles computer processing speeds with existing hardware by simultaneously using graphics processing units (GPUs), hardware accelerators for artificial intelligence (AI) and machine learning (ML), or digital signal processing units to process information.

Little groundwater recharge in ancient Mars aquifer, according to new models      (via sciencedaily.com)     Original source 

Mars was once a wet world. The geological record of the Red Planet shows evidence for water flowing on the surface -- from river deltas to valleys carved by massive flash floods. But a new study shows that no matter how much rainfall fell on the surface of ancient Mars, very little of it seeped into an aquifer in the planet's southern highlands.

New water batteries stay cool under pressure      (via sciencedaily.com)     Original source 

A global team of researchers has invented recyclable 'water batteries' that won't catch fire or explode. The team use water to replace organic electrolytes -- which enable the flow of electric current between the positive and negative terminals -- meaning their batteries can't start a fire or blow up -- unlike their lithium-ion counterparts.

Electrification or hydrogen? Both have distinct roles in the European energy transition      (via sciencedaily.com)     Original source 

A key step to achieving climate neutrality in the European Union is to rapidly shift from fossil fuels to electric technologies powered by renewable energies, a new study shows. At the same time, hydrogen produced from electricity will also be indispensable in hard-to-electrify sectors such as aviation, shipping and chemicals. By 2050, electrification and hydrogen are the key strategies to reach climate neutrality based on renewable power.

Evidence of geothermal activity within icy dwarf planets      (via sciencedaily.com)     Original source 

A team found evidence for hydrothermal or metamorphic activity within the icy dwarf planets Eris and Makemake, located in the Kuiper Belt. Methane detected on their surfaces has the tell-tale signs of warm or even hot geochemistry in their rocky cores, which is markedly different than the signature of methane from a comet.
