The visual exploration tools built for the SkyServer make it easy to visualize and explore detailed astronomical data in regions of the sky covered by the Sloan Digital Sky Survey. One can specify regions of interest by central position and size. An underlying web service then combines the relevant images to form a JPEG mosaic* at the requested wide range of resolutions. One can overlay additional useful information, including:
*Note: The Finding Chart, Navigate and Image Lists tools build mosaics on the fly by overlapping SDSS fields that may or may not belong to different runs. The field area displayed in the overlap region is determined by the (arbitrary) order in which the fields are being superimposed by the mosaicing software. However, the sky may have changed from one run to the next. Observations of moving or variable objects like meteors, satellites, comets, variable stars, etc. may appear in one run but not in the other, or be different from one run to the other. We suggest that if you want to carefully examine any object(s) close to a field boundary, you should use either the Get Image by Field tool which displays the whole JPEG frame for individual fields in each run, or get the FITS file from the Explorer or the Data Archive Server.
