| Cassini also carries tools to study cosmic dust around Saturn, as well as the planet's auroras and its odd magnetic field. |
|
| Colorful sky lights called auroras may be active at high latitudes and possibly into northern U.S. states and Europe. |
|
| Although the solar wind produces beautiful auroras, it can also cause a variety of undesirable consequences. |
|
| The Hubble Space Telescope has spotted auroras near the poles of both Saturn and Jupiter. |
|
| As it is, auroras on Earth follow magnetic lines of force that converge at the north and south magnetic poles. |
|
| By knowing how auroras react to the solar wind, scientists can better determine the impacts of space weather in the future. |
|
| He expanded on their work by pulling in historical records of auroras, naked-eye sunspots, and eclipses. |
|
| Leaving the grey stone of the city, we stepped into a world of resplendent greens with splashes of colour as bright as the auroras themselves. |
|
| The Roman philosopher Seneca proposed that the auroras were flames slipping through cracks in the heavenly firmament. |
|
| And then last week another big storm that caused auroras and beautiful geo magnetic activity all over the world. |
|
| I chat with a graduate student on his first trip down to the South Pole to make radio measurements of the southern auroras. |
|
| The green airglow and auroras extend above the horizon, evoke sailing vessels, a tribute to Garneau's naval experience. |
|
| The colour and altitude of auroras provide a lot of information on the atmospheric gases that become excited. |
|
| The spectacular auroras form in the regions of the exosphere, the bottom of which is found at 500 kilometres above the Earth's surface. |
|
| That light is very colorful, like auroras, and it filled the whole space like a stream of water. |
|
| The continuous solar wind creates auroras all year round, including summer. |
|
| Most often, auroras are seen closer to Polar Regions as the Earth's magnetic fields direct more charged particles to these regions. |
|
| Experts used to think it was just a matter of the air being heated by particles and electric currents in the regions around the poles, where auroras occur. |
|
| But it turns out the enigmatic waves that cause auroras may actually represent a visible manifestation of complex interactions occurring between our Sun and the Earth's magnetic field. |
|
| Thus, the selection of the 2125 00 UT image as the first brightening is subjective for approximately 1 min. The auroras show faint azimuthally separated structures near the onset MLT, e.g., 2124 40 UT and 2126 20 UT panels. |
|
|
|
| Just as weather experts track hurricanes and predict their landfall, researchers want to be able to predict the onset of powerful auroras so they can safeguard power and navigation systems. |
|
| Just before a dull, faint glow turns into a shimmering dance of colourful light that fills the night sky, bizarre waves of tiny charged particles seem to ripple through continent-wide bands of auroras in the upper atmosphere. |
|
| Interactions of the Earth's electromagnetic field with the interplanetary disturbances are especially strong in the polar areas and in the surrounding 'auroral zones', where most auroras can be seen. |
|
| The interaction of solar wind with the magnetosphere, producing auroras and other phenomena, and magnetohydrodynamic generation are covered next. |
|
| There have been many studies of the Earth's magnetosphere and space weather, but these have never pinpointed exactly how the energy of the solar wind transforms explosively into auroras in the magnetosphere. |
