About the Sloan Digital Sky Survey The Sloan Digital Sky Survey , or SDSS , is an international collaboration of scientists gathering data from two telescopes in North and South America to build the most detailed Three-Dimensional Imagery of the Universe ever made. The SDSS has produced deep multi-color images of one third of the sky, and created spectra of more than three million astronomical objects. About SciServer SciServer is an NSF-supported project to build a big data platform that brings the computing to the data for extremely large datasets. Using SkyServer with your free SciServer account unlocks additional features. SciServer hosts the following web-based apps that allow you to query and analyze your data in the cloud. CasJobs Compute SciDrive SkyQueryEducational Resources Voyages is the educational website for the SDSS. Voyages serves up projects, activities, resources, and research experiences for students of all ages that build on data from the Sloan Digital Sky Survey. How do I get data? Use a Visual Tool SkyServer’s Visual Tools make it easy to visualize and explore detailed astronomical data in regions of the sky covered by the Sloan Digital Sky Survey. Search for an object with... Image List : Generate image cutouts from object positions Imaging Search : Form-based query for imaging data IR Spectroscopic Search : Form-based query for infrared spectroscopic data Spectroscopic Search : Form-based query for spectroscopic data Search for an object by location Radial Search : Search the sky around a given point Rectangular Search : Search the sky in a rectangular region EZ Search : Easy search formWhat can I do with my data? Although you don’t need to be logged in to SciServer to use SkyServer, logging in gives you greater ability to integrate with other SciServer web apps. Save your visual search results Navigate, Explore, and Quick Look let you save your results to an online Workbook. Just click Save in Workbook to save your results, and Show Workbook to view your results. Save your search results While you are logged into SciServer search forms allow you to save your data to MyDB, your own personal database. From there, your data is available in any SciServer app. Download your MyDB data from CasJobs Your MyDB tables can be viewed and downloaded from CasJobs Analyze your data with SciServer Compute Compute’s Jupyter Notebooks enable cloud-based analysis next to your data in the cloud, no downloading required. Use Python, R, and MATLAB to analyze your data in the cloud. Compare multiple databases (easy) Cross-ID is a simple tool that enables you to perform dynamic cross identifications of SDSS objects against a user defined list. Compare multiple databases (advanced) SkyQuery is a scalable database system for cross-matching astronomical source catalogs.How do I find help? Read the documentation on SciServer.
