Radiant Energy

NASA's newest climate mission has started collecting data on the amount of heat in the form of far-infrared radiation that the Arctic and Antarctic environments emit to space. These measurements by the Polar Radiant Energy in the Far-Infrared Experiment (PREFIRE) are key to better predicting how climate change will affect Earth's ice, seas, and weather—information that will help humanity better prepare for a…

A solar energy absorber that uses quartz to trap heat reached 1050°C in tests and could offer a way to decarbonise the production of steel and cement

NASA's PREFIRE mission will deploy a pair of satellites from twin launches aboard Rocket Lab's Electron rockets that will contribute to climate change...

NASA and Rocket Lab are targeting no earlier than Wednesday, May 22, 2024, for the first of two launches of the agency's PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission to study heat loss to space in Earth's polar regions.

In Spring 2024, NASA will launch two tiny twin satellites as part of the PREFIRE mission that will journey to the poles to collect data that will help...

It's possible to extract energy from primordial black holes, experts say — if they actually exist

In our solar system, little rocky Mercury is the planet orbiting closest to the sun, perpetually fried by solar radiation seven times more intense than what we experience on Earth.

Photosynthesis is a crucial process that allows plants to convert carbon dioxide into organic compounds using solar energy. Light-harvesting complex II (LHCII) is a complex of pigment molecules bound to proteins. It switches between two main functions—dissipating harmful excess light energy as heat under high light intensity through nonphotochemical quenching, and transferring absorbed light to the reaction center…

Experience the joy of The Sun Card's symbolism. Explore its interpretations, illuminating positivity, success, and inner radiance.

Invisible cloaks. Ghost imaging. Scientists are manipulating light in ways that were once only science fiction.

The early years of quantum physics, from Einstein's explanation of the photoelectric effect in 1905 through the introduction of the Schrödinger equation in 1926, was a remarkable time for sci…

Developed at Harvard, and successfully tested at Graz University of Technology (TU Graz), a revolutionary new meta-optics for microscopes with extremely high spatial and temporal resolution has proven its functional ability in laboratory tests at the Institute of Experimental Physics at TU Graz.

An international team of researchers, led by scientists at the University of Manchester, has developed a fast and economical method of converting methane, or natural gas, into liquid methanol at ambient temperature and pressure. The method takes place under continuous flow over a photo-catalytic material using visible light to drive the conversion.

There are many types of energy in the world, from potential and kinetic to electrical and thermal, along with many others. But what exactly is energy?

Atoms are fed into the system just like a pitching machine.

A tiny organism is responsible for the mystic blue-green glow of the famous bio-bays.

Visible light is the portion of the electromagnetic spectrum that can be detected by the human eye.

Shine a flashlight into a murky pond water and the beam won't penetrate very far. Absorption and scattering rapidly diminishes the intensity of the light beam, which loses a fixed percentage of energy per unit distance traveled. That decline—known as exponential decay—holds true for light traveling through any fluid or solid that readily absorbs and scatters electromagnetic energy.

Was there life on Mars? This is the question that the European Space Agency (ESA) is setting out to answer with its ExoMars mission. The mission, in which Russia is a participant, is scheduled to launch this fall, although recent political developments have raised questions as to whether this will be possible. Part of the mission is an exciting analytical system that was designed to operate in space and was created…
