translation of 'aurora'
A few years ago it was suggested that 'auroral' phenomena could exist on Mars too.
Birkeland's experiments failed to account for one of the most important traits of 'auroras' : they are common around the polar regions but exceedingly rare at the poles themselves.
Super-energized particles from the radiation belts and from 'auroral' storms can damage the sensitive electronics of satellites.
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.
There was an exceptional 'auroral' glow over the entire sky.
Although the solar wind produces beautiful 'auroras' , it can also cause a variety of undesirable consequences.
Nevertheless, the potential exists for periods of strong 'auroral' storm conditions developing during the next several days (at least).
The eventual physical effects of the storm were minimal - 'auroras' were visible in Boston and other northern U.S. cities, but no satellites or power grids had major failures.
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' .
Radio waves appear to be tied to the brightest 'auroral' spots.
Severe solar weather is often heralded by dramatic 'auroral' displays, northern and southern lights, and magnetic storms that occasionally affect satellites, radio communications and power systems.
The Hubble Space Telescope has spotted 'auroras' near the poles of both Saturn and Jupiter.
A typical example of how both missions will co-operate is the study of the magnetic substorms producing the bright 'aurorae' .
But, as the team observed, although Saturn's aurora do share characteristics with the other planets, they are fundamentally unlike the 'auroral' displays on either Earth or Jupiter.
As it is, 'auroras' on Earth follow magnetic lines of force that converge at the north and south magnetic poles.
Colorful sky lights called 'auroras' may be active at high latitudes and possibly into northern U.S. states and Europe.
He expanded on their work by pulling in historical records of 'auroras' , naked-eye sunspots, and eclipses.
And then last week another big storm that caused 'auroras' and beautiful geo magnetic activity all over the world.
Bound to the Earth, our only naturally occurring experience with space weather comes from what we can see with our eyes: eclipses, comets, 'auroras' , and sunspots.
Vivid red 'auroral' rays glowed over all over North America, stretching as far south as Arizona, southern California, Mississippi, and Texas.
Gaps in the magnetosphere also allow for one of Earth's most beautiful, eerie phenomena: the 'aurora borealis' , or northern lights.
People as far south as Virginia were treated to fantastic 'auroral' displays in the night sky.
During 'auroral' light shows, extraneous electric currents would flow through the wires, superseding the normal telegraph currents and making transmission of messages almost impossible.
