Southern aurora Earth from Space

Southern aurora Earth from Space

Two types of polar auroras occur on Earth. The southern ones are those seen at the southern end of the planet, while the borealis are seen at the North Pole. In both cases they occur at a great height, between 100 and 1,000 kilometers above sea level. For this reason they are appreciable from space, as is the case with our image, made from the International Space Station (ISS).

The auroras are produced by the collision of protons and electrons from the Sun, which are trapped in the magnetic field of the pole. In the case of the southern auroras or Southern Lights, the best places to contemplate and photograph them are Antarctica or Antarctica, in the southern regions of South America, in New Zealand and in Australia.

The ideal time to capture the southern auroras is during the autumn and the southern winter, which correspond to the spring and summer months of the Northern Hemisphere. The equinoxes are the most appropriate time. The worst time in Antarctica is between the months of October and February, since during these days there are almost 24 hours of Sun, making it impossible to see an aurora.

Scientific instruments can detect the disturbances caused by the southern auroras in the magnetic field, even if it is day, but the human eye can only see them with darkness.
