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.

The vents are emitting a black body radiation an IR signature and so they're able to find these vents at considerable distances.

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.

Yes, Divinity.

A lot of smoke from the Tiburtino!

After this happens, the electron is emitted from the nucleus into the electron cloud.

Sonar lash, Herr Kapitän. He has made contact.

California emits only seven percent of U.S. CO2 emissions.

The oxygen exhaled by those stromatolites is what we all breathe today.

Which was emitting the most CO2?

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

living in about 200 times the radiation that would kill you.

His smile, our glow as we talked a universal language of design, invisible to the chaos around us.

It is affected by gravity, but it is invisible to visible light and all other forms of electromagnetic radiation.

Stand on the rock where the people can see you and have hope!

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.

Gas emits less than half the CO2 per kWh produced, and it emits much lower amounts of other pollutants like NOx, SO2, black carbon, CO, mercury, and particulates. If the UK sold its shale gas both domestically and abroad to replace coal, it could reduce local air pollution significantly and reduce global carbon emissions by 170Mt, or more than a third of UK carbon emissions.

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

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

The current geographical location of centres around the world should be reviewed.

So why do hot objects glow? Thermodynamics.

It reduces Earth's heat radiation to space, so there's a temporary energy imbalance.

When a neutrino hits a water molecule it emits a kind of blue light, a flash of blue light, and by looking for this blue light, you can essentially understand something about the neutrino and then, indirectly, something about the dark matter that might have created this neutrino.

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.

The scope of initiatives vary according to the political situation in the programme countries.

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

The best evidence for dark matter today comes from measurements of something called the cosmic microwave background, the afterglow of the Big Bang, but that's another story.

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.

like a white light, it just emits light at particular colors, a red one, a light blue one, some dark blue ones.

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

The background radiation is simply too static to be able to be seen under the normal spectral analysis.

Professor Van Allen told me about observations of Venus, that there was intense microwave radiation.

If you are going to Jupiter, you have a very high radiation, you know, environment.

All I need now is to flip on another beam, and the bottom beam is me talking, right?

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

Use of depleted uranium weapons was weakening the human species because of the exposure to low level radiation and resulting lowering of immune systems.

Many workers in occupations involving exposure to radiation sources or radioactive material are individually monitored.

First, we assumed it was pointing along the wire with the current or perhaps, emanating outwards from the wire as heat would travel.

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

And what we've shown is that doing a sham irradiation this is the thick line here this is shining UV on the arm so it warms up but keeping it covered so the rays don't hit the skin.

Because if you can live in radiation that looks like this, that brings up a whole series of interesting questions.

Yep, the volcano emitted 150,000 tons the grounded planes would have emitted 345,000 if they were in the sky.
