An aurora [a] (pl. aurorae or auroras), [b] also commonly known as the northern lights (aurora borealis) or southern lights (aurora australis), [c] is a natural light display in Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic). Auroras display dynamic patterns of brilliant lights that appear as curtains ...
The North geomagnetic pole (Ellesmere Island, Nunavut, Canada) actually represents the South pole of Earth's magnetic field, and conversely the South geomagnetic pole corresponds to the north pole of Earth's magnetic field (because opposite magnetic poles attract and the north end of a magnet, like a compass needle, points toward Earth's South ...
The northern lights are caused by interactions between the sun's solar winds and the Earth's protective magnetic field, according to NOAA. Those two phenomenons result in geomagnetic storms and ...
Substorms can cause magnetic field disturbances in the auroral zones up to a magnitude of 1000 nT, roughly 2% of the total magnetic field strength in that region. The disturbance is much greater in space, as some geosynchronous satellites have registered the magnetic field dropping to half of its normal strength during a substorm.
The northern lights — light produced when particles from space collide with atoms and molecules in the upper atmosphere centered on Earth’s magnetic pole —are a manifestation of geomagnetic ...
One of the most common manifestations of a CME's impact on Earth are the emergence of aurora borealis, or northern lights. The interaction between the CME and Earth's magnetic field, or ...
The outflow of ions due to the ambipolar electric field end up accumulating in the plasmasphere if they follow closed magnetic field lines but ions following open magnetic field lines exit the Earth system. [13]: 167 Ions following open magnetic field lines are push away from the Sun by forces of the solar wind (anti-solar convection).
The northern lights could dazzle millions of Americans in some northern states this weekend. An eruption of solar material from the sun earlier this week could lead to a show of the aurora ...
