Self-lofting devices propelled by sunlight have been tested for the first time in near-vacuum conditions akin to those in Earth’s upper atmosphere, paving the way for a revolution in atmospheric science. The tiny, lightweight membranes — which are made of aluminum oxide and a layer of chromium — take advantage of a phenomenon known as photophoresis, which occurs when one …

NASA’s Parker Solar Probe has delivered its closest and most detailed view yet of the Sun’s atmosphere, revealing the chaotic origins of the solar wind and space weather events that ripple across the solar system. The findings, based on a historic flyby in December 2024, reported by SciTechDaily, are reshaping scientists’ understanding of how the Sun’s activity can disrupt satellites, …

A study analyzing data from NASA’s Parker Solar Probe has uncovered evidence of a “helicity barrier” in the Sun’s atmosphere. In 2018, NASA launched the Parker Solar Probe on a trajectory that would eventually have it dive into the Sun’s atmosphere (corona), getting seven times closer to our host star than any other spacecraft so far. In June 2025, the …

NASA had a special Christmas gift last year. On December 24, the Parker Solar Probe reached the closest it will ever get to the Sun. As it flew just 6.1 million kilometers (3.8 million miles) from its surface, it snapped a picture of the solar wind, the stream of particles that is released from the Sun, which can travel at …

A groundbreaking global study, recently published in Nature, reveals surprising findings about the state of ancient carbon storage and its impact on the atmosphere. For decades, scientists have assumed that carbon trapped deep in soils and rocks, often for thousands or even millions of years, was securely contained, unaffected by the forces of nature and human activity. However, a new …

“Potentially Huge Implications” – Scientists Discover Ancient Carbon Is Leaking Into the Atmosphere  SciTechDaily Source link

A groundbreaking study using Apollo 16 lunar samples has challenged long-held assumptions about the source of the Moon’s delicate atmosphere. Contrary to the belief that the solar wind plays a dominant role, new findings indicate that micrometeorite impacts are actually the primary drivers of the Moon’s tenuous exosphere. Why Solar Wind Fell Short Of Expectations For decades, scientists have debated …

If you want to capture the majesty of the Sun, you should probably ask an artist, but if you want to capture its raw power, that’s a job for a robot. While generations of artists have painted or photographed sunsets and poets have written sonnets to the Sun, NASA’s Parker Solar Probe (PSP) just sent back the closest solar snapshots …
