Stellarium Presentation Notes

  * It’s a planetarium software, it simulates the night sky showing the position of the Moon, planets and distant objects from any location and time.
  * It is available to everyone and easy to use
  *   It can be downloaded on your pc, Mac or android

  * There’s a left and bottom panel
  * To change location use left panel and click on the location window. Choose any location from the list or set coordinates if known. It can be set as default.
  * Move cursor 360° to show night sky at that time.
  * Click on an object and zoom in and out, using page up and down or forward and back slash. Show how to deselect the object.

  * Speed up and show how the celestial sphere rotates about a point.
  * The fixed point appears to be the North Star, Polaris, which much to contrary believes is not the brightest star in the night sky.
  * The sky appears to rotate because the Earth rotates about an axis. If we project an imaginary line this axis points to where this star is located.
  * Earth rotates anticlockwise at about a thousand miles an hour. The sky appears to rotate clockwise, the stars rise and set from East to West.

  * The best object to observe at this time is Jupiter, because it’s at its closest point to the Earth since 1963.
  * It is also called “the amateur’s planet”, because it is bright in the night sky therefore easy to locate and have many features to observe. Its cloud belts and its moons.
  * Click on it and zoom in to show Ganymede, Io, Callisto, Europa and speed up to show how the moons rotate [remember to tell them / make sure to lock].
  * First man to discover its moons was Galileo with an early version of a...
