If you have an object name, coordinates in the sky, some keywords, an image or catalog, this page can help you answer questions, provide additional data, or make custom data products. Listings below give some avenues for how the VO can bring answer questions, provide additional data, or make custom data products.

IF I HAVE an object name:
Convert to position in the sky:-
Use the Sesame Name Resolver
Look up known information about the object:

-
Go to NED Photometry
-
-
IF I HAVE a sky position/radius:
Get color image:-
Use the SDSS finding chart tool
-
Use Virtual Sky
-
Use Skyview
Find images from multiple surveys
