Here is Shane's interactive Flat Earth Model that can explain Sunrise, Sunset, Moonrise, Moonset, Moon Phases, Moon s apparent rotation, Sun s position on Equinox, Seasons, some aspects of Solar and Lunar Eclipses, Star trails, 24 hours Day Night at the Northpole and Antarctica, Celestial Poles, why people south of the equator can see the same ...

When we refer to the celestial sphere, we are imagining that everything we see on the sky is set on the inside of a huge spherical shell that surrounds the Earth. We will use the reference points of the celestial sphere as the basis for several coordinate systems used to place celestial locations with respect to one another and to us. ”

One way to make a flat ‘map of outer space’ would be to cut the celestial sphere into two halves, press both hemispheres flat, and print the two flattened hemispheres on opposite sides of a disk. We would then have the whole celestial globe in the form of a flat double-sided disk.

The Rotating Sky Explorer consists of a flat map of the Earth, Celestial Sphere, and a Horizon Diagram that are linked together. The explanations below will help you fully explore the capabilities of the simulator. You may click and drag either the celestial sphere or the horizon diagram to change your perspective.

Demonstrates latitude and longitude on an interactive flat map of the celestial sphere. Shows how the declination of the sun varies over the course of a year using a horizon diagram. Shows the paths of the sun on the celestial sphere.

2002年11月6日 · The wheel is a map of the stars. It shows a part of the starry sphere (celestial sphere). When we take a sphere and make a flat map of it, we have to stretch it. The stretching is especially noticeable around the edges of the map.

1979年6月30日 · Here's an article in the NY Times describing the map: New World Map And, here's a Scientific American article about the map: The Most Accurate Flat Map Of Earth Yet

The astrolabe uses stereographic projection to map the celestial sphere onto a flat plane. This projection works because we're observing a dome-like sky above a flat plane, not a curved surface. The astrolabe measures altitude (height above the horizon) and azimuth (direction) of celestial bodies.

Using a globe-earth model, you can create a spherical star map that plots the exact position of every star and constellation visible from Earth. You can test this and show that it works consistently with 100% accuracy from any place and any time on Earth. Astronomy software uses this model. Telescopes are programmed according to this model.

3. Add the following to your celestial sphere flat map a. Place a small circle around Polaris (the north star) b. Draw in the celestial equator c. Draw in the ecliptic d. Label the locations: vernal equinox, summer solstice, autumnal equinox, winter solstice 4. Notate the following positions on your graph a. α = 12 h 45’ δ = -35º b.
