Google unveiled another free service today, the Google Sky web browser. The Google Sky web browser lets you view images of space in a web browser instead of having to install Google Earth. This is a great thing for teachers and students in school districts that haven’t installed Google Earth on school computers and aren’t allowed to install programs. (Yes, some districts really don’t let teachers install any programs).

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.”

Here is a short video introduction to the Google Sky web browser.
