WikiSky has a lot of information and images, but not as much as some professional astronomer’s tools. If you are really curious about some object you found on sky map and you want to trace it to the source, try NASA’s SkyView online tool. Well, it may be not that easy to navigate as WikiSky, but it is a great tool.
Check out the gallery of what SkyView’s users found there: http://skyview.gsfc.nasa.gov/userimages/gallery-1.html. I saw there many familiar objects, including our famous “spaceships” and many other “suspicious objects”.
One good thing about all that “spaceships” story, is that many people raised they eyes to the sky, some curious ones did investigation and got some knowledge, some found out about all the beauty and mystery about astronomy. And for me, who loves astronomy and science in general, it is a good thing. After all it is one of the main reason we created and continue working on WikiSky project
