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 electrons from the sun interact with the Earth's magnetic field and collide with various molecules in our atmosphere. "And because of those interactions eventually light is released.
It is believed that the reversal is correlated to the Earth's mantle, although exactly how is still debated. [13] Distortions to the Earth's magnetic field cause the phenomenon Aurora Borealis, commonly called the Northern Lights. [14] The magnetic field stores energy given by cosmic particles known as solar wind, which causes the magnetic ...
This week, marvel at the sun’s complexity, discover a new side to Stonehenge, meet a clever corvid, explore a newly observed region of a black hole, and more.
Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun.
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 ...
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 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 ...
