Astronomy & Astrophysics Research Guide: Data Sources & Almanacs

Find open data sets and resources relating to data visualization, analysis, APIs, coding and related advice and search tools.

NOAA's National Geophysical Data Center, Solar-Terrestrial Physics Division's monthly summary of geomagnetic activity & "space weather." Describes variations in the earth's geomagnetic field arising from irregular current systems caused by solar radiation changes, and magnetosphere interactions with solar wind and the ionosphere.

2nd edition of this data resource is freely available online; 3rd edition is available for purchase in print format.

Search, browse and explore planetary data sets covering different aspects of planetary science, including: Atmospheres, Geosciences, Cartography and Imaging Sciences, Planetary Plasma Interactions, Ring-Moon Systems, and Small Bodies.

Use this searchable database to find multiwavelength data (from gamma rays through radio frequencies) for extragalactic objects integrated from hundreds of large sky surveys and tens of thousands of research publications. Provides links to multiple data sources, including NASA astrophysics mission archives (IRSA, HEASARC, MAST); the astrophysics literature via ADS; and other data centers around the world.

Find data, tables, calendars, time-scales, coordinate systems, search tools, notes and glossaries associated with astronomical phenomena (e.g. eclipses), stars, stellar systems, planets, moons, and other Solar System bodies..

Calculate rise/set times for sun/moon/planets.

Provides rise/transit/set times for the sun, moon, planets and stars worldwide; provides sunrise/sunset azimuths, and transit altitudes.
