Jul 23, 2024 · The northern lights are created when energized particles from the sun slam into Earth's upper atmosphere at speeds of up to 45 million mph (72 million kph), but our...
The aurora's characteristic wavy patterns and 'curtains' of light are caused by the lines of force in the Earth’s magnetic field. The lowest part of an aurora is typically around 80 miles above the Earth's surface. However, the top of a display may extend several thousand miles above the Earth. What are the different colours in the aurora?
Jun 10, 2021 · Nothing can ruin our joy in the aurora borealis, or northern lights, those ribbons of blue, green and violet light that cascade from the sky. Not even knowing for sure what causes them.
As a simple answer, the Northern Lights happen when high-energy particles from the sun (solar wind) collide with the oxygen and nitrogen atoms present in our magnetosphere. The energy released from this interaction is what produces the light we see in the sky.
Oct 12, 2024 · What causes northern lights? The sun sends more than heat and light to Earth — it sends energy and charged particles known as the solar wind. But sometimes that solar wind becomes a storm. The sun’s outer atmosphere occasionally “burps” out huge bursts of energy called coronal mass ejections.
In northern latitudes, the effect is known as the aurora borealis or the northern lights. The southern counterpart, the aurora australis or the southern lights, has features almost identical to the aurora borealis and changes simultaneously with changes in the northern auroral zone. [ 13 ]
The northern lights, or aurora borealis, are a spectacular, colourful display of light commonly seen in the night sky in the northern hemisphere. Auroras in the southern hemisphere are known as the southern lights, or aurora australis.
Sep 8, 2022 · Storms on the sun that cause events such as coronal mass ejections and solar wind from coronal holes send charged particles hurtling across space. Because our sun is 93...
It creates a phenomenon called solar wind. When such charged particles enter the upper atmosphere or ionosphere, auroras emerge. In the northern pole, it is called aurora borealis (northern lights), while in the southern pole, it is called aurora australis (southern lights).
Mar 13, 2022 · The northern lights are a phenomenon that appear in the sky when charged particles coming from the sun slam into oxygen and nitrogen molecules in the atmosphere, ionizing those molecules and...
