Alexander von Humboldt
Friedrich Wilhelm Heinrich Alexander von Humboldt (14 September 17696 May 1859) was a Prussian polymath, geographer, naturalist, explorer, and influential proponent of Romantic philosophy and science.

Earth's shadow
Earth's shadow or Earth shadow is the shadow that Earth itself casts onto its atmosphere and into outer space, toward the antisolar point.

Ecliptic
The ecliptic is the circular path on the celestial sphere that the Sun follows over the course of a year; it is the basis of the ecliptic coordinate system.

Heiligenschein
Heiligenschein (German for "halo" or "aureola") is an optical phenomenon in which a bright spot appears around the shadow of the viewer's head.

Interplanetary dust cloud
The interplanetary dust cloud, or zodiacal cloud, consists of cosmic dust (small particles floating in outer space) that pervades the space between planets in the Solar System and other planetary systems.

Interplanetary medium
The interplanetary medium is the material which fills the Solar System, and through which all the larger Solar System bodies, such as planets, dwarf planets, asteroids, and comets, move.

Kordylewski cloud
Kordylewski clouds are large concentrations of dust that may exist at the and Lagrangian points of the Earth–Moon system.

Lagrangian point
In celestial mechanics, the Lagrangian points (also Lagrange points, L-points, or libration points) are positions in an orbital configuration of two large bodies, wherein a small object, affected only by the gravitational forces from the two larger objects, will maintain its position relative to them.

Light pollution
Light pollution, also known as photopollution, is the presence of anthropogenic light in the night environment.

Lunar phase
The lunar phase or phase of the Moon is the shape of the directly sunlit portion of the Moon as viewed from Earth.
New!!: Gegenschein and Lunar phase · See more »
Opposition surge
The opposition surge (sometimes known as the opposition effect, opposition spike or Seeliger effect) is the brightening of a rough surface, or an object with many particles, when illuminated from directly behind the observer.

Optical phenomena
Optical phenomena are any observable events that result from the interaction of light and matter.
New!!: Gegenschein and Optical phenomena · See more »
Scattering
Scattering is a general physical process where some forms of radiation, such as light, sound, or moving particles, are forced to deviate from a straight trajectory by one or more paths due to localized non-uniformities in the medium through which they pass.

Sunlight
Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light.

Sylvanshine
Sylvanshine is an optical phenomenon in which dew-covered foliage with wax-coated leaves retroreflect beams of light, as from a vehicle's headlights.

Theodor Brorsen
Theodor Johan Christian Ambders Brorsen (July 29, 1819 – March 31, 1895) was a Danish astronomer.

Zodiacal light
Zodiacal light (also called false dawn when seen before sunrise) is a faint, diffuse, and roughly triangular white glow that is visible in the night sky and appears to extend from the Sun's direction and along the zodiac, straddling the ecliptic.
