Solar flares are the most powerful events in the solar system and the\nbrightest sources of X-rays, often associated with emission of particles\nreaching the Earth and causing geomagnetic storms, giving problems to\ncommunication, airplanes and even black-outs. X-rays emitted by accelerated\n...
electrical power grid(电网) is particularly likely to be affected by these extr a currents, which can go into high-voltage transmission lines, causing transformers to overheat and possibly burn out." Across the nation, electric services and grid operators are preparing to respond to such problems...
it unleashed a rare solar radiation storm, as a cloud of high-energy particles was accelerated to near the speed of light by the energy of the flare. Solar radiation storms are capable of causing problems with orbiting
阅读理解 The 2012 London Olympics had enough problems to worry about.But one more has just been added - a communications blackout caused by solar storms. After a period of calm within
The amount of irradiance that reaches the surface can vary due to Earth’s elliptical orbit, solar flares and the amount of atmosphere the radiation must pass through (due to the sun’s angle to the surface or cloud cover present).
Now scientists believe that this peak could result in vast solar explosions that could throw billions of tons of charged matter towards the Earth causing strong solar storms that could jam the telecommunications (通信) satellites and interact links sending five Olympic broadcast from London. “The ...
I might not have done any further research on solar flares after 1980 if Zdeněk Švestka (memoir by him, Švestka 2010) had not continued, one by one, to present flare-related problems to me that he thought were solvable with high-quality observations in Hα. After completing an early...
There are several ways in which solar storms affect satellites. As solar wind particles mix with molecules of air, for example, the atmosphere warms up and swells, causing the density of the tenuous gases in the atmosphere's upper layers to increase. Spacecraft in low Earth orbit, including...
But it wasn't only solar flares that mesmerized astronomers in recent days. They also got the chance to see a monstrous burst ofplasmaerupt from the sun. An elongated solar filament that extended almost half the sun's visible hemisphere erupted into space on April 28-29, 2015, in a large...
The most powerful geomagnetic storm possible walloped the Earth early Wednesday, knocking out some airline communications but apparently causing no large power outages or other major problems. The storm, the most disruptive to hit Earth since 1989, was unleashed by the fourth-most powerful solar fl...
