PITTSBURGH &#8212 The heavens are only a few mouse clicks away with Google Inc.’s latest free tool.

A new feature in Google Earth, the company’s satellite imagery-based mapping software, allows users to view the sky from their computers.

The tool provides information about various celestial bodies, from stars to planets, and includes imagery from the Hubble Space Telescope and other sources.

It also allows users to take virtual tours through galaxies, including the Milky Way, from any point on Earth they choose.

The new software also promises users the ability to see planets in motion and witness a supernova.

“What’s unique about this is you have all of the imaging data over the whole of the sky actually streaming. So I can look at something that covers most of the sky, say our Milky Way galaxy, and I can zoom right into a tiny galaxy that’s in the formation cycle,” said Andrew Connolly, a University of Washington associate professor of astronomy and part of Google’s visiting faculty program.
