But the images suggest that scientists will want to take advantage of the DNB's images in multiple ways: not just to study clouds, but also to assess disasters such as power outages (such as before and after Superstorm Sandy last month), to study gas flares and estimate volumes of CO2 emissions, or to keep an eye on illegal unreported fishing (the boats emit light to draw in their stocks).

Collapsing out of dense pockets of hydrogen gas early in the universe's history, the first stars flickered on, emitting ultraviolet light that interacted with the surrounding hydrogen.

The energy concentration is now so high that the residual gas contained within the bubble is heated to incandescence temperatures and emits light.

In fact it's positively chilly, with more than half the energy emitted by normal matter coming from clouds of gas and dust too cold to radiate visible light — and which therefore can not be seen with traditional telescopes.

The spectrum of light emitted by these jets, says Dopita, reveals that they are made of «common or garden interstellar gas».

WHAM telescope The Wisconsin Hydrogen - Alpha Mapping telescope focuses on the light emitted by hot hydrogen gas.

LEDs are also more efficient than fluorescent light bulbs, which require less electricity than Edison's invention to excite gases to emit light.

The gas glows because young, extremely hot stars like these are emitting intense ultraviolet light which strips the surrounding gas of its electrons and causes it to emit the faint glow seen in this image.

In their paper, Townes and Schawlow presented the idea of arranging mirrors at each end of a cavity containing a gas or substance that could be excited to emit light.

[2] Neutral hydrogen gas absorbs all the high - energy ultraviolet light emitted by hot young stars very efficiently.

Astronomers have found an enormous, glowing blob of gas in the distant universe, with no obvious source of power for the light it is emitting.

As they heat and compress the gas, the shock waves emit light.

The light emitted by old stars and clumps of hot pristine gas from the early universe suggest helium made up some 25 per cent of the ordinary matter created during the big bang.

Albert Einstein proposed in 1917 that the right wavelength of light can stimulate an excited atom to emit light of the same wavelength, essentially amplifying it, but Townes was stymied by how to corral a gas of excited atoms without them flying apart.

Webb's giant sunshield will protect it from stray heat and light, while its large mirror enables it to effectively capture infrared light, bringing us the clearest picture ever of space objects that emit this invisible radiation beyond the red end of the visible spectrum — early galaxies, infant stars, clouds of gas and dust, and much more.

However, testing these predictions has proven to be extremely challenging, because such gas at the edges of galaxies is so rarefied that it emits very little light.

The blue colour of this nebula is typical of a reflection nebula - the gas and dust in the nebula do not emit any light, instead it is merely reflecting light from stars within the nebula.

The moss consists of hot gas at about two million degrees Fahrenheit which emits extreme ultraviolet light observed by the TRACE instrument.

Solar moss consists of hot gas at about two million degrees Fahrenheit which emits extreme ultraviolet light observed by the TRACE instrument.

That cooler gas barely emits any light.

That the nebula is so much brighter than the star shows that the star emits primarily highly energetic radiation of the non-visible part of the electro - magnetic spectrum, which is absorbed by exciting the nebula's gas, and re-emitted by the nebula, at last to a good part in the visible light.

This condition is produced by the strong ultraviolet light emitted from the very luminous, hot stars embedded in the gas.

As we pass up through the photosphere, the temperature drops and the gases, because they are cooler, do not emit as much light energy.

Their nuclei emit jets of high - velocity gas (near the speed of light) above and below the galaxy — the jets interact with magnetic fields and emit radio signals.

Some ghost GRBs also may be so far away that many wavelengths of light emitted by them may become absorbed by intergalactic gas.

These star - formation rate estimators include the ultraviolet light that is emitted from young stars, the infrared light that shows how much of the ultraviolet light was absorbed by dust, and the nebular emission lines that are caused by young stars making the clouds of gas around them glow and radiate.

In the collision region, the hot gas emits strong amounts of light.

An even more interesting possibility, however, is that x-ray flashers come from explosions in even more distant regions of the universe, where cosmic expansion since the Big Bang would have shifted emitted gamma rays into the x-ray range and intergalactic gas blocks visible afterglow, as none of these x-ray flashes have been observed to have a detectable, visible - light afterglow.
