Enhance your photography with an in-depth look at the star explosion effect. Learn what settings and approaches you need to capture beams of light, and how Star Filter Kit is your goal for creative brilliance. What is the effect of a star explosion? ‘Diffraction’ is a photographic term you may be familiar with. Otherwise, diffraction basically means scattering of light. As photographers, we understand this optical phenomenon as a bad thing because it is associated with a loss of sharpness. But diffraction is also responsible for creating the dreamy starburst effect in photos where the sun or a harsh light source creates a pointed beam of light. What does aperture have to do with the starburst effect? The starburst effect in photography is largely controlled and determined by your aperture, and more specifically, your aperture blade. If you ask two photographers to capture the same sun, they will likely produce different starburst effects due to their choice of lenses and the numb

Space launches, particularly early morning space launches, cause spectacular glowing clouds to appear in new places, according to new research published in the journal Advancing Earth and Space Science. About 50 miles (80 kilometers) above the ground floats the tallest clouds in Earth’s atmosphere. Called noctilucent, mesosphere, or polar mesosphere clouds, these crystallized pools of water vapor are high enough to reflect sunlight, even after sunset or even before sunrise. Because of their position in the upper atmosphere, when they are present at the right time, noctilucent clouds (i.e. “night rays”) sparkle with otherworldly light. They can make the sky at dusk or dawn look like the surface of the sea on a clear day — silvery ripples of light between patches of darkness. “You see it for about 30 minutes to an hour and a half after sunset, or before sunrise,” Cora Randall, an atmospheric scientist at the University of Colorado, Boulder, and one of the researchers on the new study,

Graphical representation of phase transitions. Credit: Koen Pieterse In Science TU/e researchers have published their study of new phase transitions of solutions and gels in water, which seem to contradict the basic principles of chemistry, and which they discovered by accident. In chemistry, hydrogels turn into liquids by diluting them with water. For the reverse transition, you increase the hydrogel concentration. However, TU/e ​​researchers led by Bert Meijer accidentally discovered that their liquid solution turned into a hydrogel when diluted. This phenomenon has never been studied or described before and can have consequences in many fields in chemistry and biology. This study focuses on the formation of certain hydrogels. This means that it starts with an aqueous solution of, in this case, two substances (a surfactant and a monomer). Research shows that gels form at a certain ratio of these two substances in water. This gel
