Another great program that came with the EeePC is Star Map or Stellarium. You
put in your Lat Long and tell it what direction you are facing and it shows you
what the night sky looks like and names the stars and planets  at that very
second. I wish I had this when I was learning to navigate using s sextant. The
only way it could be better is with a plug in GPS and a compass :) This free
program alone is worth the price of the EeePC. http://www.stellarium.org/

Google Earth version 4.3 has that now. If you locate a spot on the
earth, in the Google Earth we normally use, then click the Saturn icon
(labeled "Sky") in the toolbar row, it shows the sky over that
location.  Starting with the constellations, and zooming out from there.
You can zoom in or out, and move around just as you do on the Earth part
of the program. All the objects are labeled and have links (if you click
them) to more information about them.

Tours and tutorials are included that can also be turned on and off.

The program lists the declination and right ascension of the cursor as
you move it around, and the arcdegrees (the width of the view at it's
current zoom level).

Although I couldn't find a reference to it, as you scroll around the
universe, placemarks that were placed in normal Google Earth keep
showing up (like my home address).  I assume the view at that point is
directly over those placemarks.

It also has a timeline so you can pick a date and time, or allow to
advance at a selected rate by itself.
