New Celestia Planetarium Scripts for schools.

adminLeave a comment

I have now made it quicker and easier to download the scripts for the moving journey through the solar system that is great for KS2 up school presentations. These can be run on a PC or MAC and can even be connected to an interactive whiteboard. I have used this for school science week shows.

Just click on the Inner or Outer Solar system product and enter your email and it will be sent FREE to your computer.

There are notes on the home page on how to install Celestia first on PC or MAC (Simple and FREE)

Calm message to you all from Selsey
I will need to give the telescope a once over and clean.  Then back to my stars!!

  3. Abstract: Post-common envelope binary systems evolve when matter is transferred from the primary star at a rate that cannot be accommodated by its secondary companion. A common envelope forms which is subsequently ejected resulting in a system with a binary period frequently between 2 and 3 hours. Where circumbinary companions are predicted, it remains unclear whether they form before or after the common en…
