Like its brighter and fast-moving relative the aurora, night airglow has strong emissions at specific wavelengths. |
|
Thanks to scientific satellites which monitor the sun, it is possible to know in advance when an aurora might occur. |
|
The orangish arc extending to the left from the aurora is airglow viewed edgewise on the limb of the Earth. |
|
By studying how the ionosphere reacts to the experiments, scientists can begin to understand how it behaves during natural airglow and aurora. |
|
I was able to watch the aurora for 30 minutes before the sky began to cloud over. |
|
Seen from space, an aurora appears as a ring of energy circling a planet's polar region. |
|
In the southern hemisphere, sky watchers saw the aurora australis over New Zealand, Australia, and South Africa. |
|
This causes the phenomenon called the northern lights, also known as the aurora borealis. |
|
When geomagnetic activity is low, the aurora typically is located, in the hours around midnight, at about 67 degrees magnetic latitude. |
|
The triangular snowflake is no more interesting than a four-leaf clover, ball lightning, or the aurora borealis. |
|
After dreaming up a death ray and an artificial aurora to light the world at night, he died in a hotel tending his pet pigeons. |
|
Although we can't claim the aurora borealis as our own, Alberta's north is blessed with prime viewing spots. |
|
In the aftermath, the solar particles rain down on the atmosphere and can be seen in remarkable displays of aurora borealis, or northern lights. |
|
During a typical three-hour substorm, the aurora near midnight exhibits a sequence of changes called the auroral substorm. |
|
Connors uses the aurora borealis-a persistent feature of the region's sky-as a tool to forecast space weather. |
|
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 flow of the solar wind around the Earth's magnetosphere is the ultimate power source for the aurora. |
|
At this time of year the aurora borealis can occasionally be seen on the northern horizon during moderate auroral activity. |
|
When it has reached the peak of perfection, my spiritual smile, like an infinite aurora, shall be in all the universe, from which all stains, all misery, all pain, and all imperfection will have passed. |
|
Last night the sky, from twenty to thirty miles in the rear, toward the east, was brilliant, as tho with the glare of the aurora borealis, from dusk to dawn. |
|
|
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. |
|
In Canada, we build and use auroral imagers, magnetometers and ionospheric radars, as well as satellite and rocket instruments for studying the aurora. |
|
The science behind this is not fully understood, but the two equinoctial periods in spring and autumn tend to produce an increase in aurora compared with winter and summer. |
|
The Latin term for gold, aurum, and the earlier Sabine ausum are said to be words of early Italian origin related to aurora meaning the glowing dawn. |
|
For example, in the solar wind they interact with the Earth's magnetosphere giving rise to Birkeland currents and the aurora. |
|
Some Inuit looked into the aurora borealis, or northern lights, to find images of their family and friends dancing in the next life. |
|
Lighting his path are the stars, a sliver of moon and the faint green glow of the aurora australis, the southern lights. |
|
Species stocked include Atlantic salmon, aurora trout, brook trout, brown trout, splake, lake trout, lake whitefish, rainbow trout, walleye, muskellunge and Chinook salmon. |
|
The aurora are created when solar wind particles are guided by the magnetic flux lines into the Earth's polar regions where the lines the descend into the atmosphere. |
|
Mrs B Albrighton, Warks 2BECAUSE of its location in the far north of Britain and the lack of light pollution, the Shetlands are a perfect place to see the aurora borealis. |
