The auroras are the result of a complex interaction between the solar wind and the Earth’s magnetic field. Here’s what happens. The sun’s heat charges the particles in the solar wind, a stream of electrically charged subatomic particles that continually emanates from the sun. As the ...
Auroras are predicted tonight and also tomorrow night, with aforecast of Kp 5. These auroras are the result of an incoming CME. The CME is predicted to be a slow glancing blow. TheKp 5prediction could mean that the storm could reach as far south as the northern USA, Scotland, Ireland, ...
Several active sunspot regions are featured in this image of the Sun's magnetic activity from August 8, 2024. Immense structures known as 'coronal loops' arch out from the Sun's surface, connecting to the Sun at the bright spots. Each of these loops has ...
The auroras occur in the ionosphere.The ionosphere is the layer of the upper atmosphere where high- energy solar radiation strips electrons from oxygen and nitrogen atoms, and leaves them as positively charged ions.The auroras are the result of a complex interaction between the solar wind and the...
答案:B本题细节定位于倒数第二段最后一句话“When the solar flares that result in magnetic storms and aurora activity are very intense, aurora displays may extend as far as the southern regions of the United States”。由此可知,当太阳耀斑和极光活动非常强烈时,在远至美国的南部地区可能会出现极光。因...
Taken by astrophotographer Jeff Dai, a stunning green aurora is seen at its zenith - the highest point in the sky - so we are getting a view of the event from below. The curtain of light is seen curling as though vibrations are going through it, before straightening out again. ...
Auroras on Earth are related to the Sun’s magnetic field. The Sun’s activity increases and decreases over an 11-year period called the solar cycle. We are currently approaching the solar cycle maximum, meaning there’s a higher number of sunspots on the Sun’s surface. ...
The substorms result from the explosive reconfiguration of the tail of the magnetosphere. On Earth, they are strongly related to the variations of the solar wind and the orientation of the interplanetary magnetic field. On Jupiter, such explosive reconfigurations are rather related to an overspill...
The active regions on the Earth-facing side of the Sun on July 29, 2024. AR's 3765, 3766, and 3767 have been emitting moderate to strong solar flares and several coronal mass ejections since July 27, which are expected to result in geomagn...
Solar storms are immense clouds of charged solar particles that sweep out through the solar system. When one passes by Earth, these charged particles interact with the planet's magnetic field, causing a disturbance known as a geomagnetic storm, which can ...
