Beijing, September 22nd - Astronauts have released another breathtaking video that shows the Aurora Australis as seen from the International Space Station as it passed over eastern Australia on September 11th. These spectacular light shows are more common near the Arctic and Antarctic regions.
The charged particle stream released by the sun (also known as solar wind) interacts with the Earth's magnetic field, causing oxygen and nitrogen atoms (the main components of the air we breathe) to collide in the upper atmosphere, creating this stunning visual spectacle. This beautiful image of the aurora was captured during a geomagnetic storm. This storm may have been triggered by a coronal mass ejection from the sun (a phenomenon where the sun ejects particles, often associated with sunspots). When high-energy particles from the sun collide with oxygen atoms in the Earth's atmosphere, they release energy in the form of light particles (or photons). These auroras typically emit light at a wavelength of 0.558 micrometers, which appears to the human eye as green light.
