Search a position for all known information

Use DataScope to find everything that's known about a given target or region of the sky. DataScope will query hundreds of VO-enabled data resources and organize the results for your viewing.

Use a target name (e.g., 3c273) or position (e.g., 10 10 10.1, 20 20 20.2)
(in degrees, max is 2)
Some recent queries:

333.5523,-26.5831 (0.0125)
MESSIER 041 (0.25)
ngc 3115 (0.25)

Positions may be entered in decimal (dd.f, sdd.f) or sexagesimal (hh mm ss.f, dd mm ss.f) notation or as targets recognized by NED or SIMBAD.

The Size should be entered in decimal degrees.

Use the Skip cache flag to ensure that you get the latest results from all services.

The Refresh registry flag queries the VO registry to get the latest services. The registry is normally queried every hour.

By default the last few queries anyone has made are shown at the bottom of the page but there is a checkbox to keep your query from being recorded on this list.
