Not every object in the sky has been curated in WWT yet. You can still see this object as it appears in the all-sky surveys by entering specific coordinates (also under the “Search” tab), but there will not be additional images from other telescopes included yet.
To use Finder Scope to get information from Wikipedia, click on the “Research” button at the bottom of the Finder Scope screen. Click on “Information” and then select “Look up on Wikipedia.” Make sure to align the Finder Scope with the image that lists only the name of the object, not a title from a press release or from a specific photograph.
Also, keep in mind that not every object in WWT has a Wikipedia page. Many objects that have names that like HIP91792 that seem to be just a string of letters and numbers do not have Wikipedia pages. You may have...
If you cannot manually line up the Finder Scope with your desired object, you can find the thumbnail of your desired object in the bottom context bar, right click on the thumbnail, and select “Properties.” This will bring up the Finder Scope screen.
First, check to make sure the Finder Scope is lined up with the correct object. You can do this by reading the name listed on the Finder Scope and comparing it to the name of your desired object. If the object the Finder Scope is focused on is not the object you want, try moving it slightly and see if you can detect your object.
You can also check that the thumbnail that shows up on the Finder Scope matches the image you want to research. You may sometimes find that your Finder Scope is looking at an infrared image when you were trying to...
Try restoring your defaults. Click the sub-menu under the “Settings” tab (click on the little rectangle at the bottom of the tab) and click “Restore Defaults." If that still doesn't work, try closing WorldWide Telescope and then restarting it.
These "UFO's" are created by the processing of the data and images. They are likely caused by internal reflections of the telescope. They are not real objects, just a projected image from the telescope.
The streaks and lines that appear in WWT, but are not astronomical objects, are usually imperfections in the imagery of the telescopes. Many line segments are the result of things like meteors, aircraft, and satellites. Meteors usually show up as lines with pointy ends and a brighter middle, and are sometimes green. Satellites can present as dashed blue lines. Aircraft lines are usually fairly solid and uniform, but sometimes wiggle a bit from turbulence in the air. White lines are often "seams" between images.
