Particle radiation is the radiation of energy by means of fast moving subatomic particles.

Quite good. He also invented a word called blas, meaning astral radiation.

Epsilon rays are a form of particle radiation and are composed of electrons.

As they interact with the medium, they generate a faint light called Cherenkov radiation.

The concept of the big bang can be traced back to the discovery of the microwave background radiation in 1965.

As the universe cooled, the rest mass energy density of matter came to gravitationally dominate that of the photon radiation.

The acceleration from this curving motion induces the electron to radiate energy in the form of synchrotron radiation.

This signal is caused by cyclotron radiation from electrons that are accelerated in Jupiter's magnetic field.

However, quantum mechanical effects are believed to potentially allow the emission of Hawking radiation at this distance.

This makes the skin turn paler because less blood reaches the surface, reducing the radiation of heat.

High energy astronomy is the study of astronomical objects that release EM radiation of highly energetic wavelengths.

The word usually refers to visible light, which is visible to the human eye and is responsible for the sense of sight.

Incubation period is the time elapsed between exposure to a pathogenic organism, a chemical or radiation, and when symptoms and signs are first apparent.

BICEP (Background Imaging of Cosmic Extragalactic Polarization) and the Keck Array are a series of cosmic microwave background (CMB) experiments.

In 1804, Sir John Leslie observed that a matte black surface radiates heat more effectively than a polished surface, suggesting the importance of black body radiation.

Research has revealed that on the comparatively small area of the mountain there are 1,500 species of higher plants, 500 species of fungi, 500 species of algae, 326 species of mosses, and 200 species of lichens.

However, you notice, since empty space gives off radiation, there's actually thermal fluctuations, and it cycles around all the different possible combinations of the degrees of freedom that exist in empty space.

If you are going to Jupiter, you have a very high radiation, you know, environment. It's about the same radiation environment close by Jupiter as inside a nuclear reactor.

Since launching their campaign, they have released the first episode, launched their website on the anniversary of the earthquake on March 11 and on March 21 they will share the second episode of the series on their site.

In the 1970s, Stephen Hawking told us that a black hole, even though you think it's black, it actually emits radiation when you take into account quantum mechanics.

And we thought this was a very interesting comment on America, and a kind of self serving, not my responsibility kind of phenomenon.

In every little cubic centimeter of space, whether or not there's stuff, whether or not there's particles, matter, radiation or whatever, there's still energy, even in the space itself.

During most of a black hole's lifetime, the radiation has a low temperature and is mainly in the form of massless particles such as photons and hypothetical gravitons.
