New Google Earth 4.2 Beta (with Google Sky!)
Wednesday, 22nd August 2007 by James Turnbull
I strongly suggest you download the latest beta version of Google Earth which has, amongst other improvements, Google Sky.
Head to the View menu and select “Switch to sky” to turn your view upside down and start Sightseeing amongst the stars.
Ogle Earth has the full scoop on all the new features.
