| By studying how the ionosphere reacts to the experiments, scientists can begin to understand how it behaves during natural airglow and aurora. |
|
| Like its brighter and fast-moving relative the aurora, night airglow has strong emissions at specific wavelengths. |
|
| Click here to view a movie and narrative by Don Pettit describing some of the airglow he has seen. |
|
| The orangish arc extending to the left from the aurora is airglow viewed edgewise on the limb of the Earth. |
|
| This communication deals with the latitude correlation between variations of local zenith airglow and ionospheric data for typical winter and early summer nights. |
|
| Unlike the aurora, airglow does not exhibit structures such as arcs and is emitted from the entire sky at all latitudes at all times. |
|
| The green airglow and auroras extend above the horizon, evoke sailing vessels, a tribute to Garneau's naval experience. |
|
| Particles in the air produce airglow, which causes the background sky never to be completely black. |
|
| Even when operating in those wavelengths that penetrate to Earth's surface, an observatory in space avoids the problems of seeing caused by atmospheric turbulence and airglow. |
|
| In the daytime and during twilight, the process of resonance scattering of sunlight by sodium, atomic oxygen, nitrogen, and nitric oxide seems to contribute to airglow. |
|
| Several major scientific programs were scheduled for Antarctica, dealing with the aurora and airglow, cosmic rays, geomagnetism, glaciology, gravity measurement, ionospheric physics, meteorology, oceanography, and seismology. |
|
| The satellite, equipped with a mini-telescope, is intended to observe airglow, an atmospheric phenomenon visible on the outer fringes of the Earth's atmosphere. |
|
| Cassini scientists have already seen an airglow from Titan's nitrogen molecules caused by X-rays and ultraviolet radiation from the Sun when Titan was illuminated by the Sun. |
|
| Airglow, faint luminescence of Earth's upper atmosphere that is caused by air molecules' and atoms' selective absorption of solar ultraviolet and X-radiation. |
|
| Airglow is an atmospheric phenomenon in which photons from the sun excite air molecules, which eventually emit light at several specific wavelengths. |
