Though the sun produces more energy than we would ever need on Earth, current solar harvesting technologies are limited, and they don’t capture as much sunlight as they could. Now, a team of ...

Researchers at the University of Johannesburg have developed a new type of photocatalyst that harnesses the visible portion of the sunlight spectrum. Currently, economical and environmentally-friendly ...

The importance of solar power as a renewable energy resource is increasing. Sunlight contains high-energy UV light with a wavelength shorter than 400 nm, which can be broadly used, for example, for ...

Understanding the true colou of the Sun, along with concepts such as Rayleigh scattering, Earth's atmosphere, sunlight spectrum, and solar science, helps explain why the Sun appears different when ...

“Here are all the visible colors of the Sun, produced by passing the Sun’s light through a prism-like device. The spectrum was created at the McMath-Pierce Solar Observatory and shows, first off, that ...

Gold supraballs absorb most sunlight, boosting thermoelectric output and pointing to simpler, high-efficiency solar coatings. (CREDIT: ACS Applied Materials & Interfaces / color modification from grey ...

A Yale-led research team has discovered a molecular “device” found in nature that harvests a particular sliver of the sunlight spectrum in order to convert it into chemical energy. In a study led by ...

Ask a child to draw the Sun and they will reach for the yellow crayon. Ask an adult, and they will do the same, without thinking about it. The yellow Sun is a widespread visual convention, familiar ...

Sun is white when seen from space. Earth's atmosphere makes Sun appear yellow. Rayleigh scattering causes Sun's perceived colors. Look at a child’s drawing of the Sun and it will most likely be yellow ...
