There are several methods of searching WorldWide Telescope data. Currently only default data is searched, not data that may have been added to your own collections, community data, and so on.
WorldWide Telescope includes the following catalogs in its internal index:
- NGC: New General Catalog
- IC: Index Catalog
- M: Messier Catalog
- BSC: Bright Star Catalog
- PGC: Principal Galaxy Catalog

The Search Panel🔗
You can open the Search panel by clicking Search in the upper panel.
To search on a name, such as Polaris or M51, enter it in the text box top left. As you type the characters the search will be automatic and display thumbnails as image data is found.
Alternatively, enter an RA and Dec if you know the approximate
location of the object you are searching for. The default units are hours. You
02 31 48; any one of these means
2 hours 31 minutes 48 seconds. To enter degrees, enter a "d", for example
89d 15m 51s. These particular co-ordinates, if used for RA and Dec
respectively, are the location of the star Polaris. Click Go
to change the
view to that location, then click Search View
for a search of the current
view to be carried out, with the results again displayed in thumbnail images.
Plot Results On the Windows Client, checking the Plot Results checkbox will make the search results appear both as thumbnails and circle annotations in the view. For example, entering 20 for RA, 18 for Dec, clicking Go , Search View and Plot Results , will reveal a constellation full of objects, as shown below. Use the Finder Scope to further identify the objects.
