Solar System formed from 'poorly mixed cake batter,' isotope research shows      (via sciencedaily.com) 

Earth's potassium arrived by meteoritic delivery service finds new research led by Earth and planetary scientists. Their work shows that some primitive meteorites contain a different mix of potassium isotopes than those found in other, more-chemically processed meteorites. These results can help elucidate the processes that shaped our Solar System and determined the composition of its planets.

How a 3 cm glass sphere could help scientists understand space weather      (via sciencedaily.com) 

Space weather can interfere with spaceflight and the operation of satellites, but the phenomenon is very difficult to study on Earth because of the difference in gravity. Researchers effectively reproduced the type of gravity that exists on or near stars and other planets inside of a glass sphere measuring 3 centimeters in diameter, or about 1.2 inches. The achievement could help scientists overcome the limiting role of gravity in experiments that are intended to model conditions in stars and other planets.

Darkest view ever of interstellar ice      (via sciencedaily.com)     Original source 

Astronomers used observations from the James Webb Space Telescope (JWST) to achieve the darkest ever view of a dense interstellar cloud. These observations have revealed the composition of a virtual treasure chest of ices from the early universe, providing new insights into the chemical processes of one of the coldest, darkest places in the universe as well as the origins of the molecules that make up planetary atmospheres.

How was the solar system formed? The Ryugu asteroid is helping us learn      (via sciencedaily.com)     Original source 

Our solar system is estimated to be about 4.57 billion years old. Previous analyses of ancient meteorites have shown that minerals were created through chemical reactions with water as far back as 4.5 billion years ago. New findings from the Ryugu asteroid samples indicate that carbonates were forming from water-rock reactions several million years earlier, even closer to the solar system's beginnings.

The rich meteorology of Mars studied in detail from the Perseverance rover      (via sciencedaily.com) 

Perseverance has now completed its investigation of the atmosphere throughout the first Martian year (which lasts approximately two Earth years). Specifically, astronomers have studied seasonal and daily cycles of temperature and pressure, as well as their significant variations on other time scales resulting from very different processes.

17-pound meteorite discovered in Antarctica      (via sciencedaily.com) 

Antarctica is a tough place to work, for obvious reasons -- it's bitterly cold, remote, and wild. However, it's one of the best places in the world to hunt for meteorites. That's partly because Antarctica is a desert, and its dry climate limits the degree of weathering the meteorites experience. On top of the dry conditions, the landscape is ideal for meteorite hunting: the black space rocks stand out clearly against snowy fields.

New small laser device can help detect signs of life on other planets      (via sciencedaily.com) 

As space missions delve deeper into the outer solar system, the need for more compact, resource-conserving and accurate analytical tools has become increasingly critical -- especially as the hunt for extraterrestrial life and habitable planets or moons continues. A University of Maryland-led team developed a new instrument specifically tailored to the needs of NASA space missions. Their mini laser-sourced analyzer is significantly smaller and more resource efficient than its predecessors--all without compromising the quality of its ability to analyze planetary material samples and potential biological activity onsite.

Theoretical computations identify a solid-state hydrogen storage material's key bottleneck      (via sciencedaily.com) 

Magnesium hydride has long been touted for its potential to store large amounts of hydrogen, something essential if hydrogen is to play a role in powering a sustainable future. Yet, sluggish dehydrogenation kinetics and the high temperature required to decompose and produce hydrogen from the material have stymied its use. Now, researchers have identified why this is so, paving the way for future design guidelines and widespread commercial use.
