Fulldome

Fulldome refers to immersive dome-based video display environments.

An example of computer animation which is produced from the "motion capture" technique

Although the current technology emerged in the early-to-mid 1990s, fulldome environments have evolved from numerous influences, including immersive art and storytelling, with technological roots in domed architecture, planetariums, multi-projector film environments, flight simulation, and virtual reality.

Max Wolf

German astronomer and a pioneer in the field of astrophotography.

In 1910 Wolf proposed to the Carl Zeiss optics firm the creation of a new instrument which would become known as the planetarium.

Orrery

Mechanical model of the Solar System that illustrates or predicts the relative positions and motions of the planets and moons, usually according to the heliocentric model.

Though the Greeks had working planetaria, the first orrery that was a planetarium of the modern era was produced in 1704, and one was presented to Charles Boyle, 4th Earl of Orrery – hence the name.

In 1991, Jenoptik Carl Zeiss Jena was split in two, with Carl Zeiss AG (Oberkochen) taking over the company's divisions for microscopy and other precision optics (effectively reuniting the pre-war Carl Zeiss enterprise) and moving its microscopy and planetarium divisions back to Jena.

Celestial navigation

Ancient and continuing modern practice of position fixing using stars and other celestial bodies that enables a navigator to accurately determine their actual current physical position in space without having to rely solely on estimated positional calculations, commonly known as "dead reckoning", made in the absence of satellite navigation or other similar modern electronic or digital positioning means.

Two nautical ship officers "shoot" in one morning with the sextant, the sun altitude (1963)
The relative longitude to a position (for example Greenwich) can be calculated with the position of the sun and the reference time (for example UTC/GMT).

Celestial navigation training equipment for aircraft crews combine a simple flight simulator with a planetarium.

Star of Bethlehem

The Star of Bethlehem, or Christmas Star, appears in the nativity story of the Gospel of Matthew chapter 2 where "wise men from the East" (Magi) are inspired by the star to travel to Jerusalem.

Adoration of the Magi by Florentine painter Giotto di Bondone (1267–1337). The Star of Bethlehem is shown as a comet above the child. Giotto witnessed an appearance of Halley's Comet in 1301.
