The Gods We Can Touch is a highly intimate book, taking readers on a journey to the very heart of Aurora’s world, through her creative process and the inspiration for her acclaimed third studio album. This full-color reproduction of Aurora’s personal notebook also features all the song lyrics from the album, original album artwork and stunning photography. On 26 February 2008, THEMIS probes were able to determine, for the first time, the triggering event for the onset of magnetospheric substorms. [62] Two of the five probes, positioned approximately one third the distance to the Moon, measured events suggesting a magnetic reconnection event 96 seconds prior to auroral intensification. [63] The oldest known written record of the aurora was in a Chinese legend written around 2600 BC. On an autumn around 2000 BC, [80] according to a legend, a young woman named Fubao was sitting alone in the wilderness by a bay, when suddenly a "magical band of light" appeared like "moving clouds and flowing water", turning into a bright halo around the Big Dipper, which cascaded a pale silver brilliance, illuminating the earth and making shapes and shadows seem alive. Moved by this sight, Fubao became pregnant and gave birth to a son, the Emperor Xuanyuan, known legendarily as the initiator of Chinese culture and the ancestor of all Chinese people.

In ancient times, the Chinese did not have a fixed word for the aurora, so it was named according to the different shapes of the aurora, such as "Sky Dog" ( 天狗), "Sword/Knife Star" ( 刀星), "Chiyou banner" ( 蚩尤旗), "Sky's Open Eyes" ( 天开眼), and "Stars like Rain" ( 星陨如雨).

Beware of spoilers! Moreso than your typical KSR novel, Aurora is more plot-driven and contains several plot twists. Green: At lower altitudes, the more frequent collisions suppress the 630nm (red) mode: rather the 557.7nm emission (green) dominates. A fairly high concentration of atomic oxygen and higher eye sensitivity in green make green auroras the most common. The excited molecular nitrogen (atomic nitrogen being rare due to the high stability of the N 2 molecule) plays a role here, as it can transfer energy by collision to an oxygen atom, which then radiates it away at the green wavelength. (Red and green can also mix together to produce pink or yellow hues.) The rapid decrease of concentration of atomic oxygen below about 100km is responsible for the abrupt-looking end of the lower edges of the curtains. Both the 557.7 and 630.0nm wavelengths correspond to forbidden transitions of atomic oxygen, a slow mechanism responsible for the graduality (0.7s and 107s respectively) of flaring and fading.

Auroras are more frequent and brighter during the intense phase of the solar cycle when coronal mass ejections increase the intensity of the solar wind.

The American Journal of Science. 2nd series. 29: 92–97.A full understanding of the physical processes which lead to different types of auroras is still incomplete, but the basic cause involves the interaction of the solar wind with Earth's magnetosphere. The varying intensity of the solar wind produces effects of different magnitudes but includes one or more of the following physical scenarios. Tromholt, Sophus (1881).
