The exoplanet 51 Pegasi b lies some 50 light-years from Earth in the constellation of Pegasus. It was discovered in 1995 and will forever be remembered as the first confirmed exoplanet to be found ...

At any given moment, 89,000 terawatts of solar power hits the Earth’s surface. While significant advancements have been made in harvesting this power, existing technologies do not capture the full ...

How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...

A new type of versatile economical photocatalyst that harnesses the visible portion of the sunlight spectrum has been developed by researchers from the University of Johannesburg. It is simple to ...

At any given moment, 89,000 terawatts of raw solar power is slamming into the Earth’s atmosphere. It is a mind-boggling amount of energy. But right now, our best technologies are essentially trying to ...

In a new study published in Science, researchers have developed a new method for detecting infrared light by changing its frequency to a corresponding frequency in the range of visible light.

The experimental setup shown here incorporates on-chip optical parametric oscillator (OPO) technology to generate a frequency comb of laser-like light covering a wide range of frequencies with very ...
