The Sloan Digital Sky Survey (SDSS) is a project dedicated to mapping the universe. Over eight years of operations, it has obtained deep, multi-color images covering over a quarter of the sky and created 3-dimensional maps containing more than 930,000 galaxies and more than 120,000 quasars.
SDSS provides a SOAP API that enables users to perform a cone search of the night sky. A cone search is a (relatively) simple request for astronomical information, retrieving whatever is available for a given position in the sky and a given radius about that position. Users must describe the area of sky on which they want information in terms of RA (right-ascension), DEC (declination), and SR (search radius).
Of the many APIs we published this week, ten were highlighted on the blog by our team of writers. In this post, we’ll launch those ten into the spotlight, which included the Sloan Digital Sky Survey API. The SDSS has captured images covering more than a quarter of the sky, containing more than 930,000 galaxies and 120,000 quasars. The API allows developers to do a cone search, retrieving whatever is available for a given position in the sky and a given radius about that position.
When I'm deciding which intergalactic data set to work with, I don't want to take any half measures. That's why I'm drawn to the Sloan Digital Sky Survey (SDSS). In their own words, "The Sloan Digital Sky Survey (SDSS) is one of the most ambitious and influential surveys in the history of astronomy." Sounds like their putting the project right up there with the greats like Galileo. You can bring this level of astronomical greatness into your app via the SDSS APIs: SDSS cone search & SDSS image cut-out.
