The Sky Screen Saver shows the sky above any location on Earth, including stars (from the Yale Bright Star Catalogue of more than 9000 stars to the 7th magnitude), the Moon in its correct phase and position in the sky, and the position of the Sun and all the planets in the sky. Outlines, boundaries, and names of constellations can be displayed, as well as names and Bayer/Flamsteed designations of stars brighter than a given threshold. A database of more than 500 deep-sky objects, including all the Messier objects and bright NGC objects can be plotted to a given magnitude. The ecliptic and celestial equator can be plotted, complete with co-ordinates. To fulfill its mission as a screen saver, the sky map shifts position on the display every 10 minutes to avoid burning in those few components of the display which do not move as the Earth revolves. Installation Instructions are here.

Dark Solar System is a new 3D screensaver for Windows that shows all of the planets of our solar system, including Saturn's rings. It tells you more about dark matter and dark energy in our planetary system. In cosmology, dark energy is a hypothetical form of energy which permeates all of space and has strong negative pressure. According to the theory of relativity, the effect of such a negative pressure is qualitatively similar to a force acting in opposition to gravity at large scales. Invoking such an effect is currently the most popular method for explaining recent observations that the universe appears to be expanding at an accelerating rate, as well as accounting for a significant portion of the missing mass in the universe.
