Celestial Seasonings

The Ejs Celestial Globe model simulates the Two Sphere Universe theory of the Ancient Greeks. This theory supposes the stars to be fixed on the surface of a Celestial Sphere, with the spherical Earth at the center of this sphere. The simulation shows the motion of Sun and stars in this model, as...

PP3 creates celestial charts. It generates resolution independent sky maps of very high graphical quality. They can be used for example as illustrations in books or on web pages. Databases are included but you may use own data if you wish.

A simple java 3d virtual celestial globe. Rotate the globe, magnify it, select the level of detail to show stars and constellations, and the ecliptic. Source code available to everyone to modify it.No Open GL. Star catalogue from Wikipedia. Available plain text star catalogue.

The Equatorial Coordinates model displays the position of a star in equatorial (Right Ascension/Declination --- RA/Dec) coordinates. The horizon is shown along with the four cardinal directions (N, E, S, and W). The Latitude slider changes the latitude of the observer which is shown by the change...

The Stellar Aberration 3D Model illustrates the phenomenon known as the aberration of starlight, first reported by James Bradley in 1729. Aberration occurs because light has a finite speed, and thus light from a star takes a finite amount of time to travel through the tube of a telescope. During...

The EJS Parallactic Proper Motion Model illustrates the phenomenon known as parallactic proper motion. Proper motion refers to the progressive (non-oscillatory) apparent motion of a star relative to more distant background stars. If this apparent motion is due to actual motion of the star through...
