Under usual circumstances, the MAVEN orbiter extends well beyond the boundaries of the Martian magnetosphere. However, this changed during a solar wind void. Credit: NASA's Goddard Space Flight Center The MAVEN Mars orbiter recently observed a transient restoration of the Martian magnetosphere and a temporary tripling of its ionosphere, a region where the Sun ionizes...
Credit: Syfy Penn State researchers have uncovered a planet significantly larger than its ultracool host star, challenging previous beliefs about planet formation. Published in Science, their findings showcase a planet more than 13 times Earth's mass orbiting a star nine times less massive than our sun. This discovery contradicts existing theories on small star planet...
Recent Studies Indicate the Sun is Marginally Smaller Than Official Estimates. Credit: NASA/SDO/AIA Physicists' insistence on celestial bodies being non-perfect spheres raises questions about our understanding of their true dimensions. In the case of the Sun, renowned for its familiarity, discrepancies emerge when various methods are employed to measure its size. The International Astronomical Union, in...
The sun and the sea, both bountiful and freely available, are at the heart of a groundbreaking project aiming to create vertical sea farms that float on the ocean. These farms have the potential to produce fresh water for drinking and agriculture in a self-sufficient manner, all without human intervention. A world-first initiative by researchers...
Credit: Pixaobay While outer space lacks traditional air, it experiences a unique form of wind known as solar wind, composed of charged particles emitted by the Sun. The precise process driving this phenomenon remains unclear, but the Solar Orbiter spacecraft from the European Space Agency (ESA) has recently detected hitherto undiscovered "small-scale" eruptions on the...
Eventos disruptivos de geração solar, chamados rampas, mudarão significativamente no futuro. Credit: Pixaobay The stability of grid-connected solar power systems in Australia's renewable energy transition should take into account the potential impact of climate change, which may affect their future performance. Modeling conducted by researchers at UNSW Sydney indicates that disruptive solar generation events, known as...
Credit: iStock Sweat, akin to blood, holds valuable insights into an individual's health, and fortunately, its collection is much less intrusive. This forms the foundation for the creation of wearable sweat sensors, crafted by Wei Gao, an assistant professor of medical engineering, Heritage Medical Research Institute Investigator, and Ronald and JoAnne Willens Scholar. Expanding Substance Measurement...
A group of scientists in China has created an innovative solar-powered contraption that effectively cleanses water, making it safe for consumption. Credit: eduardkraft/Depositphotos The University of Science and Technology of China has made a breakthrough in water purification by introducing a unique wooden device that utilizes bacteria to construct essential nanostructures, enabling evaporation as a...
This innovation allows for the absorption of sunlight without compromising the view through these transparent surfaces.Credit: Masood Aslami/ pexels.com A group of scientists from Michigan State University has created a technology capable of transforming see-through surfaces, such as windows in buildings or cell phone screens, into surfaces that can collect solar energy. This innovation allows for...
The pivotal component in EPFL's innovative solar hydrogen reactor is the parabolic dish. EPFL engineers have successfully constructed and examined a solar reactor capable of harnessing sunlight and water to produce hydrogen gas. This system not only exhibits exceptional efficiency in hydrogen generation but also effectively utilizes the byproducts of oxygen and heat. Hydrogen has a...
