Aurora australis seen from the ISS, 2017. An aurora (pl. aurorae or auroras), also commonly known as the northern lights (aurora borealis) or southern lights (aurora australis), 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, rays, spirals, or ...
Feb 9, 2024 · The northern lights, or the aurora borealis, are beautiful dancing ribbons of light that have captivated people for millennia. But for all its beauty, this spectacular light show is a rather ...
This is a short-term forecast of the location and intensity of the aurora. This product is based on the OVATION model and provides a 30 to 90 minute forecast of the location and intensity of the aurora. The forecast lead time is the time it takes for the solar wind to travel from the L1 observation point to Earth.
Jun 13, 2024 · There, the particles interact with gases in our atmosphere resulting in beautiful displays of light in the sky. Oxygen gives off green and red light. Nitrogen glows blue and purple. These green bands of light in the winter sky above Alaska are an aurora borealis. This is the name for an aurora in the Northern Hemisphere. Credit: Sarah Histand.

Jun 22, 2024 · aurora, luminous phenomenon of Earth ’s upper atmosphere that occurs primarily in high latitudes of both hemispheres; in the Northern Hemisphere auroras are called aurora borealis, aurora polaris, or northern lights, and in the Southern Hemisphere they are called aurora australis or southern lights. A brief treatment of auroras follows.
The Aurora Borealis (Northern Lights) and Aurora Australis (Southern Lights) are the result of electrons colliding with the upper reaches of Earth’s atmosphere. (Protons cause faint and diffuse aurora, usually not easily visible to the human eye.) The electrons are energized through acceleration processes in the downwind tail (night side) of ...
Deehr's group contributed to the discovery that there are two great ovals of auroral activity encircling the geomagnetic poles—one for the aurora borealis in the Northern Hemisphere, one for the ...
In the Northern Hemisphere, it is called an aurora borealis or the northern lights. In the Southern Hemisphere, it is called an aurora australis or the southern lights. A brilliant stream of the southern lights or aurora australis is photographed from the International Space Station as it orbits 270 miles above the Indian Ocean near Antarctica on August 17, 2022.
