The northern lights, explained. What caused the most recent outburst of the northern lights? ... The electrons from the sun interact with the Earth's magnetic field and collide with various ...
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 ...
What causes the northern lights. ... As auroras form, Earth's magnetic field redirects the particles toward the poles through a process that produces a stunning display of rays, spirals and ...
The northern lights, seen here in Oregon in May, might be visible in parts of the U.S. on New Year's Eve. ... A CME explosion is caused by the sun’s magnetic field and, like in this case, can ...
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 sun and the intense magnetic activity it generates which causes the northern lights, waxes and wanes on an 11-yearlong solar cycle. The peak of activity – the solar maximum – occurs when ...
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 may be visible as far south ... Strong eruptions aimed at Earth can cause disturbances in the planet’s magnetic field, knocking out power grids and damaging infrastructure ...
