	Reference.com/Encyclopedia/Aurora (planet)
		The planet was the very first extrasolar colony world established by mankind, founded at some point prior to 2064 A.D. (and following the discovery of the hyperspatial jump in 2029 A.D.), with numerous extrasolar colonies being mentioned by Susan Calvin during an interview given in that year.
		Aurora at its height had a population of 200,000,000 humans and 10,000,000,000 robots.
		The largest 'city' on the planet was Eos, the administrative and robotic centre of Aurora where Han Fastolfe and Gladia Solaria lived.

	Saturn's Aurora Defy Scientists' Expectations
		Aurora on Saturn behave in ways different from how scientists have thought possible for the last 25 years, according to new research by a team of astronomers led by John Clarke, a professor in BU’s Department of Astronomy and in the department’s Center for Space Physics.
		The strong brightening of the aurora on 28 January corresponded with the recent arrival of a large disturbance in the solar wind.
		This difference suggests that Saturn’s aurora are driven in an unexpected manner by the sun’s magnetic field and the solar wind and that the planet’s aurora possibly have different physical states at different times.

		The Aurora is a beautiful natural phenomenon, that occurs most often in the Polar regions of Earth, in the form of majestic, colorful, and irregular lights in the night sky.
		The word Aurora Australis refers to the Aurora that occurs in the southern hemisphere (southern lights), whereas Aurora Borealis refers to the Aurora that occurs in the northern hemisphere (northern lights).
		The North American Indians considered the Aurora to be the Gods dancing across the night sky, and the Eskimos in Greenland and the Hudson Bay area thought that the northern light was the kingdom of the dead.

	The Nine Planets Glossary
		the inclination of a planet's orbit is the angle between the plane of its orbit and the ecliptic; the inclination of a moon's orbit is the angle between the plane of its orbit and the plane of its primary's equator.
		A "dwarf planet" is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape2, (c) has not cleared the neighbourhood around its orbit, and (d) is not a satellite.
		A synchronous satellite with an orbital inclination of zero (same plane as the planet's equator) stays fixed in the sky from the perspective of an observer on the planet's surface (such orbits are commonly used for communications satellites).

	Aurora FAQ
		Aurora Alerts Forum and from various e-mails sent to me. For each question there is a short, one-sentence answer, and a paragraph or two with a bit more explanation.
		Aurora is a luminous glow of the upper atmosphere which is caused by energetic particles that enter the atmosphere from above.
		Since all planets are embedded in the solar wind, all planets are subjected to the energetic particle bombardment, and thus all planets that have a dense enough atmosphere will have some sort of aurora.

	NASA - Auroras Spotted from Space
		Aurora were visible as far south as Florida Thursday night after a coronal mass ejection (CME) was hurled into space by sunspot 484.

		The two portions of the aurora finally meet on the opposite side of the planet, where it is midnight local time, forming a ring.

		The cause of these aurora is the capture of the charged particles by the Earth's magnetic field.
		The solar wind is also responsible for the tail seen on comets and the fact that this tail always points away from the sun.
		When the solar wind encounters a comet or planet, a bow shock is formed which is analogous to the shock waves studied in classes on compressible flow and gasdynamics.

		Near the north pole the light show is called the aurora borealis and near the south pole it is called aurora australis.
		UV photographs of Jupiter indicate that auroral phenomena occur in its polar regions.
		Like the aurora near the Earth's poles, the glowing display near Jupiter's poles comes from the interaction of charged particles with the planet's magnetic field, which is more intense near the poles.

	EO Newsroom: New Images - IMAGE Spacecraft Pictures Aurora
		From space, the aurora is a crown of light that circles each of Earth’s poles.
		The IMAGE satellite captured this view of the aurora australis (southern lights) on September 11, 2005, four days after a record-setting solar flare sent plasma—an ionized gas of protons and electrons—flying towards the Earth.
		Though scientists knew that the aurora were caused by charged particles from the Sun and their interaction with the Earth’s magnetic field, they had no way to measure the interaction until NASA launched the Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) satellite in 2000.

		Auroras on Jupiter remain relatively constant in both intensity and extent.
		Saturn's auroras also differ from Earth's in that they become brighter on the sector of the planet where night is turning to day.

		While Hubble observes the aurora, a team of Cassini scientists led by University of Michigan's Dr. David Young, principal investigator for the Cassini plasma spectrometer instrument is measuring variations in the solar wind that might be causing the auroral fluctuations.
		At both planets, auroras are useful indicators of conditions in the magnetic field surrounding the planet, since particles steered by the magnetic field toward the planet's poles are what stimulate the glow.
		Researchers are studying features of the aurora and examining possible relationships to how the solar wind affects Jupiter's magnetosphere, a vast environment of charged particles surrounding the planet under the influence of Jupiter's magnetic field.

	ESA - Aurora Exploration Programme - The European Space Exploration Programme Aurora
		The objective of the Aurora Programme is first to formulate and then to implement a European long-term plan for the robotic and human exploration of solar system bodies holding promise for traces of life.
		Some of the key technologies for a human mission are also very important to the search for life in situ on the red planet and on other solar systems, planets and moons.
		Thus the Aurora Programme can be seen as a road map for human exploration, from which a large number of scientific as well technology spin-offs will emerge, driven by the goal of exploration.
