Someone recently emailed me after reading this post about Google Sky for Android to ask if there were similar tools available for use on laptops. The answer is yes. Here are three tools that students can use to explore space from their desktops.

The Microsoft WorldWide Telescope makes very detailed, high resolution images (scientific quality) from space available to anyone with access to a computer and an internet connection. The goal of the WorldWide Telescope is to enable users to use their computers as virtual telescopes. The WorldWide Telescope can be downloaded and run on Windows-based computers. Mac users will have to use the web client to access the WorldWide Telescope. The educators page on the WorldWide Telescope site has lesson resources and ideas for middle school and high school use.

Celestia is a
free space exploration simulation program. Celestia is a free download
that works on Mac, PC, and Linux systems. The advantage of Celestia over
other satellite imagery programs is that in addition to seeing the
Earth’s surface, students can zoom in on moons, stars, and planets. The
user controls what they see. Operating the program is easy enough to be
used by students as young as six or seven. The user guides for Celestia are very thorough and available in four languages. There is a companion website to Celestia called the Celestia Motherlode that features add-ons to Celestia and educational activities that teachers can use in their classrooms.

Google Sky allows you view images of space in your web browser. Google Sky offers great images of outer space captured by the Hubble Space Telescope and the Sloan Digital Sky Survey. Google Sky has images that have captured x-ray and infrared wavelengths. The Google Sky web browser also has some more basic images in a collection referred to as “backyard astronomy.”
