Diffuse Horizontal Irradianceis the amount of radiation received per unit area by a surface that does not arrive on a direct path from the sun, but has been scattered by molecules and particles in the atmosphere. Basically, it is the illumination that comes from clouds and the blue sky. ...
No, photovoltaic modules like solar panels generate electricity under various conditions, including ambient, diffuse, and indirect sunlight.However, the total wattage a PV array generates is negatively impacted when sunlight is obstructed by conditions such as clouds or shade....
WIMPs don't even seem to interact with each other through anything more than gravity, meaning dark matter does not fuse to form larger or more complex molecules and remains in a simple—and highly diffuse—gas-like state. The first-ever composite image of a dark matter "bridge" that ...

Another type of diffuse nebula, a reflection nebula doesn’t emit its own light, but scatters light from embedded stars. (Image credit: NASA, JPL-Caltech, Kate Su (Steward Obs, U. Arizona) et al.) Planetary nebula: The Helix Nebula This is composed of expanding gas that was blown off...
Stellar objects that can be called Nebula come in four major classes. Most fall into the category of Diffuse Nebulae, which means they have no well-defined boundaries. These can be subdivided into two further categories based on their behavior with visible light –“Emission Nebulae” and “Refl...
It's tempting to think of the Local Interstellar Cloud as being like a fog, but it is very diffuse.According to Professor Barbara Ryden of Ohio State University, the ISM's density can get as low as 0.1 atoms per cubic centimeter (although in the biggernebulae, the density can reach 10,...
Space infrared observations from cooled telescopes have been providing significant information on our understanding of interstellar dust grains because they are sensitive to "diffuse emission" from the interstellar medium of the entire Galaxy, which is difficult to observe with warm telescopes. This paper...
Why is methane the worst greenhouse gas? Is it just because its a huge molecule? What are the determinants of how gases diffuse? What is the function of carotenoids? 1. What is global warming? 2. Describe how human activities impact glob...
Answer to: The ozone molecules in the upper atmosphere (stratosphere) absorb much of the UV radiation from the sun. What is the temperature of the...
