Published Hunting Venus 2.0: Scientists sharpen their sights
(via sciencedaily.com) With the first paper compiling all known information about planets like Venus beyond our solar system, scientists are the closest they've ever been to finding an analog of Earth's 'twin.'
Published Ultra-lightweight multifunctional space skin created to withstand extreme conditions in space
(via sciencedaily.com) A new nano-barrier coating could help protect ultra-lightweight carbon composite materials from extreme conditions in space, according to a new study.
Published Uracil found in Ryugu samples
(via sciencedaily.com) Samples from the asteroid Ryugu collected by the Hayabusa2 mission contain nitrogenous organic compounds, including the nucleobase uracil, which is a part of RNA.
Published 3000+ billion tons of ice lost from Antarctic Ice Sheet over 25 years
(via sciencedaily.com) Original source Scientists have calculated that the fastest changing Antarctic region?-?the Amundsen Sea Embayment?-?has lost more than 3,000 billion tonnes of ice over a 25-year?period.??
Published Galaxy changes classification as jet changes direction
(via sciencedaily.com) A team of international astronomers have discovered a galaxy that has changed classification due to unique activity within its core. The galaxy, named PBC J2333.9-2343, was previously classified as a radio galaxy, but the new research has revealed otherwise.
Published ESO telescopes on the aftermath of DART's asteroid impact
(via sciencedaily.com) Using ESO's Very Large Telescope (VLT), two teams of astronomers have observed the aftermath of the collision between NASA's Double Asteroid Redirection Test (DART) spacecraft and the asteroid Dimorphos. The controlled impact was a test of planetary defence, but also gave astronomers a unique opportunity to learn more about the asteroid's composition from the expelled material.
Published Genome research: Origin and evolution of vine
(via sciencedaily.com) Cultivation and growth of grapevines have strongly influenced European civilizations, but where the grapevine comes from and how it has spread across the globe has been highly disputed so far. In an extensive genome project, researchers have determined its origin and evolution from the wild vine to today's cultivar by analyzing thousands of vine genomes collected along the Silk Road from China to Western Europe.
Published 'Terminator zones' on distant planets could harbor life
(via sciencedaily.com) In a new study, astronomers describe how extraterrestrial life has the potential to exist on distant exoplanets inside a special area called the 'terminator zone,' which is a ring on planets that have one side that always faces its star and one side that is always dark.
Published Evidence that Venus is volcanically active
(via sciencedaily.com) Venus appears to have volcanic activity, according to a new research paper that offers strong evidence to answer the lingering question about whether Earth's sister planet currently has eruptions and lava flows.
Published Remains of a modern glacier found near Mars' equator implies water ice possibly present at low latitudes on Mars even today
(via sciencedaily.com) Scientists revealed the discovery of a relict glacier near Mars' equator. Located in Eastern Noctis Labyrinthus at coordinates 7° 33' S, 93° 14' W, this finding is significant as it implies the presence of surface water ice on Mars in recent times, even near the equator. This discovery raises the possibility that ice may still exist at shallow depths in the area, which could have significant implications for future human exploration.
Published Extensive catalog of exploding stars
(via sciencedaily.com) The largest data release of relatively nearby supernovae (colossal explosions of stars), containing three years of data is publicly available via the Young Supernova Experiment (YSE).
Published Mix-and-match kit could enable astronauts to build a menagerie of lunar exploration bots
(via sciencedaily.com) The Walking Oligomeric Robotic Mobility System, or WORMS, is a reconfigurable, modular, multiagent robotics architecture for extreme lunar terrain mobility. The system could be used to assemble autonomous worm-like parts into larger biomimetic robots that could explore lava tubes, steep slopes, and the moon's permanently shadowed regions.
Published Webb Telescope captures rarely seen prelude to supernova
(via sciencedaily.com) The rare sight of a Wolf-Rayet star -- among the most luminous, most massive, and most briefly detectable stars known -- was one of the first observations made by NASA's James Webb Space Telescope in June 2022. Webb shows the star, WR 124, in unprecedented detail with its powerful infrared instruments. The star is 15,000 light-years away in the constellation Sagittarius.
Published New study finds early warning signs prior to 2002 Antarctic ice shelf collapse
(via sciencedaily.com) In 2002, an area of ice about the size of Rhode Island dramatically broke away from Antarctica as the Larsen B ice shelf collapsed. A new study of the conditions that led to the collapse may reveal warning signs to watch for future Antarctic ice shelf retreat, according to a new scientists.
Published Scientists call for global push to eliminate space junk
(via sciencedaily.com) As almost 200 countries agree a legally-binding treaty to protect the High Seas, a collaboration of experts in ocean plastic pollution and satellite technology has urged world leaders to learn lessons from the management of the High Seas and act now to protect Earth's orbit.
Published Major North American oil source yields clues to one of earth's deadliest mass extinctions
(via sciencedaily.com) Geologists studying the Bakken Shale Formation discovered a critical kill mechanism behind a series of extinctions some 350 million years ago.
Published Short-distance migration critical for climate change adaptation
(via sciencedaily.com) Short-distance migration, which accounts for the vast majority of migratory movements in the world, is crucial for climate change adaptation, according to new research. Contrary to common assumptions, most migratory movements are people moving short distances, largely due to economic, social and environmental factors, such as climate change.
Published How does the immune system react to altered gravity?
(via sciencedaily.com) Space travel has always tested the human body by the effects of the new conditions of altered gravity on biological systems. It has long been known that continuous exposure to microgravity conditions human physiology and causes effects that compromise muscular, sensory, endocrine and cardiovascular functions. But is it also risky to be exposed to altered gravity for short periods of time?
Published Flat, pancake-sized metalens images lunar surface in an engineering first
(via sciencedaily.com) Astronomers and amateurs alike know the bigger the telescope, the more powerful the imaging capability. To keep the power but streamline one of the bulkier components, a research team created the first ultrathin, compact metalens telescope capable of imaging far-away objects, including the moon.
Published Elegantly modeling Earth's abrupt glacial transitions
(via sciencedaily.com) Original source Milutin Milankovitch hypothesized that the timing of glacial transitions has been controlled by the orbital parameters of the Earth, which suggests that there may be some predictability in the climate, a notoriously complex system. Now researchers propose a new paradigm to simplify the verification of the Milankovitch hypothesis. The new 'deterministic excitation paradigm' combines the physics concepts of relaxation oscillation and excitability to link Earth's orbital parameters and the glacial cycles in a more generic way.
