"The almanac module for the DRUPAL CMS provides twilight times, sunrise/set and moonrise/set data for any location. This can be a useful addition to sites that include astronomy, religious, education, energy-related, weather, or astrology information. Sites devoted to a range of outdoor activities, from night photography to fishing, can also benefit from adding an almanac.
Multipurpose planetarium. One of the best around, and still getting better... The organization of the menus is particularly innovative and the graphical display options very flexible. The negative point is its slowness, particularly with all the design trimmings activated; also, it does not allow direct printing.
On the graphical side, it offers the classical representation of the celestial sphere; the situation of the sky over the local horizon; elongations and heliocentric position of the planets and a tool to draft/register your sunspot observations.
AstroCalc enables you to :
- To calculate the position of planets and give their appearance.
- To calculate hours of Rising/Transit/Setting
- Visualization of the apparent diameter of planets ones compared to the others…
- Visualization of the position of planets on the ecliptic.
- Visualization of planets in heliocentric position.
- Positions of the satellites around Jupiter, as seen from Earth.
- Calculate the position of comets...
- Download the appearance of the sun directly on web ( SoHo ).
The Electric Astrolabe is a fully animated planetarium program in the form of a planispheric astrolabe.

Einstein's General Theory of Relativity demonstrates that a large mass can deform space-time and bend the path of light. So, a very massive object, such as a cluster of galaxies can act as a gravitational lens. When light passes through the cluster from an object lying behind it, the light is bent and focused to produce an image or images of the source. The image may be magnified, distorted, or multiplied by the lens, depending upon the position of the source with respect to the lensing mass.
