Astronomical Computation & Data

The Wolfram Language provides seamless access to the curated and continuously updated Wolfram Knowledgebase used in Wolfram|Alphawhich includes a wide range of types of data for astronomical science. Free-form linguistics provide a convenient mechanism for accessing all available data; more common categories also have specific associated Wolfram Language functions.
