Exquisite views of distant galaxies      (via sciencedaily.com)     Original source 

For decades, the Hubble Space Telescope provided us with the most spectacular images of galaxies. This all changed when the James Webb Space Telescope (JWST) launched and successfully completed commissioning. For astronomers, the universe is now revealed in a new way never imagined by the telescope's Near-Infrared Camera (NIRCam) instrument.

Sound recording made of dust devils (tiny tornadoes of dust, grit) on Mars      (via sciencedaily.com) 

When the rover Perseverance landed on Mars, it was equipped with the first working microphone on the planet's surface. Scientists have used it to make the first-ever audio recording of an extraterrestrial whirlwind.

First ultraviolet imaging of Sun's middle corona      (via sciencedaily.com) 

Researchers have discovered web-like plasma structures in the Sun's middle corona. The researchers describe their innovative new observation method, imaging the middled corona in ultraviolet (UV) wavelength. The findings could lead to a better understanding of the solar wind's origins and its interactions with the rest of the solar system.

Hubble detects ghostly glow surrounding our solar system      (via sciencedaily.com) 

Imagine walking into a room at night, turning out all the lights and closing the shades. Yet an eerie glow comes from the walls, ceiling, and floor. The faint light is barely enough to see your hands before your face, but it persists. Sounds like a scene out of a scary movie?" No, for astronomers this is the real deal. But looking for something that's close to nothing is not easy.

Climate whiplash increased wildfires on California's west coast about 8,000 years ago      (via sciencedaily.com) 

Researchers have been studying the effects of the sudden decrease in global temperatures that occurred about 8,200 years ago, the so-called 8.2-kiloyear event, with the help of mineral deposits present in White Moon Cave in Northern California. New indications show that oscillations between extreme wetness and aridity in California were closely linked with the occurrence of wildfires. The researchers have concluded that such events are likely to become more common in the face of human-induced climate change.

Americans flocking to fire: National migration study      (via sciencedaily.com) 

Americans are leaving many of the U.S. counties hit hardest by hurricanes and heatwaves -- and moving towards dangerous wildfires and warmer temperatures, says one of the largest studies of U.S. migration and natural disasters. These results are concerning, as wildfire and rising temperatures are projected to worsen with climate change. The study was inspired by the increasing number of headlines of record-breaking natural disasters.

For 400 years, Indigenous tribes buffered climate's impact on wildfires in the American Southwest      (via sciencedaily.com)     Original source 

Devastating megafires are becoming more common, in part, because the planet is warming. But a new study suggests bringing 'good fire' back to the U.S. and other wildfire fire-prone areas, as Native Americans once did, could potentially blunt the role of climate in triggering today's wildfires.

Meteorites plus gamma rays could have given Earth the building blocks for life      (via sciencedaily.com) 

Even as detailed images of distant galaxies from the James Webb Space Telescope show us more of the greater universe, scientists still disagree about how life began here on Earth. One hypothesis is that meteorites delivered amino acids -- life's building blocks -- to our planet. Now, researchers have experimentally shown that amino acids could have formed in these early meteorites from reactions driven by gamma rays produced inside the space rocks.

Tiny underwater sand dunes may shed light on larger terrestrial and Martian formations      (via sciencedaily.com)     Original source 

Researchers have been studying the dynamics of how crescent-shaped sand dunes are formed. Known as barchans, these formations are commonly found in various sizes and circumstances, on Earth and on Mars. Using a computational fluid dynamics approach, the team carried out simulations by applying the equations of motion to each grain in a pile being deformed by a fluid flow, showing the ranges of values for the proper computation of barchan dunes down to the grain scale.

Giant mantle plume reveals Mars is more active than previously thought      (via sciencedaily.com) 

Orbital observations unveil the presence of an enormous mantle plume pushing the surface of Mars upward and driving intense volcanic and seismic activity. The discovery reveals that Mars, like Earth and Venus, possesses an active interior, which challenges current views on the evolution of the red planet.

'Digital footprints' central to new approach for studying post-disturbance recreation changes      (via sciencedaily.com) 

A new social media-based study of recreation visitation in the Gorge following the Eagle Creek Fire expands on research launched in 2016 -- and holds promise for other large, multi-ownership landscapes. The study shows how using new approaches that draw from social media data can help us better understand the complex relationships between wildfire, natural resource management, and people.

Small asteroids are probably young      (via sciencedaily.com)     Original source 

The impact experiment conducted on the asteroid Ryugu by the Japanese Hayabusa2 mission which took place two years ago resulted in an unexpectedly large crater. With the use of simulations, a team has recently succeeded in gaining new insights from the experiment regarding the formation and development of asteroids.

Major fires an increasing risk as the air gets thirstier, research shows      (via sciencedaily.com) 

Greater atmospheric demand for water means a dramatic increase in the risk of major fires in global forests unless we take urgent and effective climate action, new research finds. Researchers have examined global climate and fire records in all of the world's forests over the last 20 years.

When cyclones and fires collide...      (via sciencedaily.com) 

As strong winds and torrential rains inundate Australia's south-eastern coast, new research suggests that high intensity bushfires might not be too far behind, with their dual effects extending damage zones and encroaching on previously low-risk residential areas.

NASA's Webb catches fiery hourglass as new star forms      (via sciencedaily.com) 

NASA's James Webb Space Telescope has revealed the once-hidden features of the protostar within the dark cloud L1527, providing insight into the beginnings of a new star. These blazing clouds within the Taurus star-forming region are only visible in infrared light, making it an ideal target for Webb's Near-Infrared Camera (NIRCam).

Mars was once covered by 300-meter deep oceans, study shows      (via sciencedaily.com) 

When Mars was a young planet, it was bombarded by icy asteroids that delivered water and organic chemistry necessary for life to emerge. According to the professor behind a new study, this means that the first life in our solar system may have been on Mars.
