The Sloan Digital Sky Survey only has about 25% of the sky covered, but in much more detail, comprising hundreds of millions of images.įor all the images captured by Hubble, you can see bigger versions of the images, and then link out to press releases and additional resources on the web. The Digitized Sky Survey covers almost the entire sky, contains about a million objects.
The images of the entire sky are made up from the Digitized Sky Survey and the Sloan Digital Sky Survey. You can click on the special objects, like the Orion Nebula, and then see the Hubble photograph of the region. It allows you to zoom around the heavens, with various Hubble Space Telescope images highlighted. This new addition to Google Earth is called “Sky in Google Earth”. Well, some clever Google engineers have flipped the software inside out, letting you explore the Universe with a similar interface. You know Google Earth, that cool software application that lets you explore satellite photography of the whole planet. They then use a kmz file, compiled by the author, which includes layers showing seafloor age, locations and depths of 20 years worth of large earthquakes, USGS dynamically updated near-real time earthquakes, volcano locations, 'hot-spot' tracks with age dates.
All right, this is the coolest thing ever. Students are introduced to Google Earth, and then start by exploring the major physiographic features of the continents and seafloor.
