Google Sky

Previously only available via Google Earth, which you had to download and run locally, Google have now made Google Sky available online to access anywhere with an internet connection.

Now you can browse the night sky and zoom in on any interesting galaxies or star clusters that you like.

If you haven't tried them, also check out Google Mars and Google Moon for surface maps based on information from various Moon and Mars missions.

Remember you can use the camera function in your interactive whiteboard software to make any screengrabs from any part of the map and bring it into your IWB software to annotate over the top. You can also put these images into your resource library/gallery for later use.
