Illuminations Reflections Of Earth

SunClock is a lightweight Dashboard widget that displays the sunlight portion of the Earth. It is based on the code from the Konfabulator widget EarthFall by Nate Barkei. Currently, you can choose between two maps, a realistic one and a Macintosh System 7 one. Platforms: Mac

Earth is under fire by Colossus, a battleship the size of a city. Using powerful laser cannons, it has destroyed most of Earth's defence forces, while its many troops clean up the rest of the planet. All expect for 5 warriors. The Battletoads, who are well aware of evil forces in the galaxy, join... Platforms: Windows

The Stellar Aberration 2D 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... Platforms: Mac

This screensaver shows you off the beautiful images of smart dolphins. People like dolphins very much and it is believed that they are one of Earth's most intelligent animals. Dolphins occasionally leap above the water surface, sometimes performing acrobatic figures that look very... Platforms: Windows

The Eratosthenes model displays the shadows cast by two gnomons (sticks) at different locations on Earth. For one gnomon, Sun is directly overhead (as would be the case if the gnomon was on the Tropic of Cancer at the summer solstice). The other gnomon is due north of the first gnomon. The sizes...

The Ejs Copernican System model illustrates Copernicus' system of planetary motions. The entire system is centered on the center of Earth's uniform, circular orbit. Sun is placed near, but not at, this center point. The orbit of each planet (other than Earth) consists of a deferent circle,... Platforms: Mac

The Astronomical Parallax 2D Model illustrates the phenomenon of parallax in astronomy. Parallax is the apparent displacement of an object relative to the background that is caused by the motion of the observer (rather than the motion of the object itself, or of the background). This simulation... Platforms: Mac

GEOPoint is an easy to use satellite antenna pointing calculator, for geostationary communications satellites. It calculates the azimuth and elevation pointing angles from a given location on the earth towards a specified geostationary satellite. The program also calculates polarisation tilt...

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...
