Devi, the ship's de facto chief engineer and leader, is concerned about the decaying infrastructure and biology of the ship: systems are breaking down, each generation has lower intelligence test scores than the last, and bacteria are mutating and evolving at a faster rate than humans. She tells the ship's AI, referred to simply as Ship, to keep a narrative of the voyage. After having some trouble with understanding the human concept of narrative, Ship eventually elects to follow the life of Devi's daughter Freya as a protagonist.
It’s part of the thinking going on in 2312 and Shaman, and so I think the three books will make a kind of argument for what we are and what we can or should try to become in the future.In northern latitudes, the effect is known as the aurora borealis or the northern lights. The former term was coined by Galileo in 1619, from the Roman goddess of the dawn and the Greek name for the north wind. [11] [12] 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 aurora australis is visible from high southern latitudes in Antarctica, Chile, Argentina, South Africa, New Zealand and Australia. The aurora borealis is visible from areas around the Arctic such as Alaska, the Canadian Territories, Iceland, Greenland, Norway, Sweden, Finland, Scotland, and Siberia. On rare occasions the aurora borealis can be seen as far south as the Mediterranean and the southern states of the US. Early work on the imaging of the auroras was done in 1949 by the University of Saskatchewan using the SCR-270 radar. [ citation needed] The altitudes where auroral emissions occur were revealed by Carl Størmer and his colleagues, who used cameras to triangulate more than 12,000 auroras. [18] They discovered that most of the light is produced between 90 and 150km (56 and 93mi) above the ground, while extending at times to more than 1,000km (620mi). Niall Alexander for Tor.com: "its depiction of the ascent of artificial intelligence must be among the most momentous takes on the topic science fiction has ever seen" The conversation was carried on for around two hours using no battery power at all and working solely with the current induced by the aurora, and it was said that this was the first time on record that more than a word or two was transmitted in such manner. [73] Such events led to the general conclusion that These forms are consistent with auroras being shaped by Earth's magnetic field. The appearances of arcs, rays, curtains, and coronas are determined by the shapes of the luminous parts of the atmosphere and a viewer's position.

Loomis, Elias (November 1859). "The great auroral exhibition of August 28 to September, 1859". The American Journal of Science. 2nd series. 28: 385–408. That aurora is thought to have been produced by one of the most intense coronal mass ejections in history. It is also notable for the fact that it is the first time where the phenomena of auroral activity and electricity were unambiguously linked. This insight was made possible not only due to scientific magnetometer measurements of the era, but also as a result of a significant portion of the 125,000 miles (201,000km) of telegraph lines then in service being significantly disrupted for many hours throughout the storm. Some telegraph lines, however, seem to have been of the appropriate length and orientation to produce a sufficient geomagnetically induced current from the electromagnetic field to allow for continued communication with the telegraph operator power supplies switched off. [74] The following conversation occurred between two operators of the American Telegraph Line between Boston and Portland, Maine, on the night of 2 September 1859 and reported in the Boston Traveler: When we last saw Squad 312, they were working together seamlessly (aka, freaking out) as an intergalactic battle raged and an ancient superweapon threatened to obliterate Earth. Everything went horribly wrong, naturally.
An aurora was detected on Mars, on 14 August 2004, by the SPICAM instrument aboard Mars Express. The aurora was located at Terra Cimmeria, in the region of 177° east, 52° south. The total size of the emission region was about 30km across, and possibly about 8km high. By analyzing a map of crustal magnetic anomalies compiled with data from Mars Global Surveyor, scientists observed that the region of the emissions corresponded to an area where the strongest magnetic field is localized. This correlation indicated that the origin of the light emission was a flux of electrons moving along the crust magnetic lines and exciting the upper atmosphere of Mars. [95] [97] N. (2003).

I just finished a starship novel in which people in a multi-generational starship try to get to Tau Ceti and occupy one of the planets around that star (actually a big moon of one of the planets). Problems follow..."

PMC 6710897. PMID 31378171. Acceleration of auroral charged particles invariably accompanies a magnetospheric disturbance that causes an aurora. This mechanism, which is believed to predominantly arise from strong electric fields along the magnetic field or wave-particle interactions, raises the velocity of a particle in the direction of the guiding magnetic field. The pitch angle is thereby decreased and increases the chance of it being precipitated into the atmosphere. Both electromagnetic and electrostatic waves, produced at the time of greater geomagnetic disturbances, make a significant contribution to the energizing processes that sustain an aurora. Particle acceleration provides a complex intermediate process for transferring energy from the solar wind indirectly into the atmosphere.Hamacher, D. W. (2013).

Rotation creates .83 g centrifugal force. St Paul famously wrote that these three things remain faith, hope and love, but the greatest of these is love. Geomagnetic storms that ignite auroras may occur more often during the months around the equinoxes. It is not well understood, but geomagnetic storms may vary with Earth's seasons. Two factors to consider are the tilt of both the solar and Earth's axis to the ecliptic plane. As Earth orbits throughout a year, it experiences an interplanetary magnetic field (IMF) from different latitudes of the Sun, which is tilted at 8 degrees. Similarly, the 23-degree tilt of Earth's axis about which the geomagnetic pole rotates with a diurnal variation changes the daily average angle that the geomagnetic field presents to the incident IMF throughout a year. These factors combined can lead to minor cyclical changes in the detailed way that the IMF links to the magnetosphere. In turn, this affects the average probability of opening a door [ colloquialism] through which energy from the solar wind can reach Earth's inner magnetosphere and thereby enhance auroras. Recent evidence in 2021 has shown that individual separate substorms may in fact be correlated networked communities. [64] Auroral particle acceleration [ edit ]
