Sentences with word «airglow»

Trapped beneath Earth's ocean of air, ground - based observatories will be stymied by starlight - warping turbulence, and by airglow — faint light emitted by atmospheric chemical reactions that can corrupt delicate observations.

Fundamental experimental data were derived from the observations of airglows by the Spectroscopy for Investigation of Characteristics of the Atmosphere of Mars (SPICAM) instrument on - board Mars Express: while NO is useful to constrain dynamics around the 100 km level (Gagné et al. 2013), CO and CO2 + UV emissions allow the direct monitoring of the efficiency of ionization processes (Stiepen et al. 2015).

A wide - field ultraviolet imager is designed to track motions of sulphur dioxide in the stratosphere, and a visible - light camera to monitor the planet's night side for airglow emissions and lightning.

Both ICON and GOLD will take advantage of a phenomenon called airglow — the light emitted by gas that is excited or ionized by solar radiation — to study the ionosphere.

To avoid airglow, we can send instruments into orbit, like the Hubble Space Telescope (for which Disney designed instruments).

By measuring the light from airglow, scientists can track the changing composition, density, and even temperature of particles in the ionosphere and neutral atmosphere.

Airglow noticeably dims when the sun is relatively quiescent, as is the case from now through 2007.

Based on the team's analyses, they estimate that the 10 - fold - or - more magnification of airglow occurs somewhere on Earth on 7 % of nights, with observers at any one spot able to see a bright night only once per year — and only then if conditions are just right.

Two upcoming NASA missions will study airglow and other properties of the ionosphere.

Although the team's analyses probably won't help regular stargazers, they could be used to help predict when enhanced airglow might interfere with the sensitive instruments used by many ground - based astronomers.

There is the possibility that they might detect some natural nightside airglow — an emission of light in the upper atmosphere produced when atoms broken apart by the solar wind recombine to form molecules, releasing energy in the form of light.

In his early stage of research, he was involved in the field of the earth's upper atmosphere like observations of terrestrial airglow and aurora, as well as the ozone layer.

From 240 miles above Earth's surface, lightning is visible as bright blotches, and city lights appear as yellow streaks; the atmosphere glows in bands of yellow, green, and red as energetic air molecules interact and emit light, a process (called airglow) that is difficult to see from the ground.

Trapped below Earth's ocean of air, even the largest ground - based observatories will be stymied by starlight - warping turbulence and by airglow, faint light emitted by atmospheric chemical reactions that can corrupt delicate observations.

Still, at altitudes above roughly 80 kilometers (50 miles) lunar tides have been detected in winds, temperature, airglow emissions and a number of ionospheric parameters.

There's still some debate though as to whether Steve is a true aurora, or perhaps a form of airglow, which results from the upper atmosphere releasing a tiny amount of light as it is warmed by the sun and the Earth's surface.

At night, an «airglow» lingers in our atmosphere as molecules radiate away the heat they soaked up during the day.

In the first picture of its kind, scientists photographed these «airglow» ripples as they washed over Hawaii hours after the quake.

This video shows this airglow as seen from the International Space Station.

Most surprising, though, was that the DNB can even see in the dim light of Earth's «airglow,» chemical reactions in the upper atmosphere that produce a faint radiance an order of magnitude brighter than starlight, said atmospheric scientist Steve Miller, deputy director of the Cooperative Institute for Research in the Atmosphere in Fort Collins, Colorado, at a press conference accompanying the unveiling.

Processes in the ionosphere also create bright swaths of color in the sky, known as airglow.

* Airglow, a kind of permanent aurora.

Around midnight the Milky Way will be largely out of view, the moon will have set, and airglow will be near its minimum.

That airglow arises when individual gas atoms — previously created when ultraviolet light blasted gas molecules apart — later recombine, the researchers explain.

Analyzing measurements of high - altitude airglow gathered by a satellite in 1992 and 1996 (years of maximum and minimum solar flare activity, respectively), the scientists found 11 cases where airglow, in theory, brightened enough to be seen by observers on the ground, they report in Geophysical Research Letters.

GLOWING HALO The colorful bands above Earth's surface, known as airglow, form when cosmic and solar rays interact with different gases in the upper atmosphere and emit light.

This enormous reservoir of charged particles plays a still - unexplained role as middleman in the interaction of Earth and sun which is reflected in magnetic storms, in the airglow and in the beautiful displays of the aurora.
