which is collectively known as ‘space weather’. Immense coronal loops stretch away from the Sun’s ‘surface’ (left), with giant prominences arcing across its surface as well. Left of centre, a solar flare causes an immense cloud of solar particles — ...
and using too much in an earthbag structure will weaken it.Gravel, or jagged pieces of rock, is sometimes used in earthbags, mostly at a foundational level, but builders primarily use a mix of clay and sand. Clay serves as the glue to hold sand together, while the loose, gritty particle...
The radius of the disk surrounding AFGL 4176 is roughly 2000 times the average distance between the Earth and the Sun. The total mass is 12 solar masses – this corresponds to just under half the weight of the star itself, which is roughly 25 solar masses. The disk rotates around the st...
“We need two ingredients for a better clarification,” Arca Sedda explains, “one or more processes capable of forming black holes within the mass range of IMBHs, and the possibility of retaining such IMBHs in the host environment. Our study places stringent constraints on the first ingredient...
Solar panels harness the free and renewable energy produced by the sun to generate electricity. While they have many advantages, they face a significant drawback: they're unable to produce electricity without sunlight. Over the years, much research has been devoted into efficiently capturing and ...
Building the International Space Station (ISS) is much like building a toy using a child's LEGO or K'nex building block set. But whereas those playthings tend to be small in scale, the ISS contains thousands and thousands of parts [source: Hollingham]. Some of the major components are li...
One approach to building a monolithic power plant is to eliminate as much heat dissipation from different components or (in the case of the high-grade quality of this waste heat) to transmit this thermal heat to valuable by-products. By materializing such an idea, the energy conversion ...
English publications and one publication in Portuguese language were considered. There were no limitations set on the literature timeline, considering that the concept of NWP is a relatively new and emerging area of scientific research and analysis. Therefore, not many articles related to NWP have ...
Much like the high-pitched sound from a fire-truck siren gets lower as the truck moves away, the movement of stars affects the wavelengths of light that we receive from them. This phenomenon is called the Doppler effect. We can measure the Doppler effect by measuring lines in a star's sp...
Despite being so hot, the corona is less than a millionth as bright as the Sun. As you walk away from a bonfire, you feel less of its heat because you receive less energy due to the inverse square law. Why is the more distant corona so much hotter than parts of the Sun closer to...
