‘Stars At Night’ lunar, solar and planetary information for Otley, West Yorkshire, UK

  • The Stars at Night is a WordPress plugin. It is intended for use by amateur astronomers and others interested in tracking astronomical data for their location. For now, that includes tables for the Moon and planets visible from your local area.
  • This is a WordPress plugin, so it is written in PHP. Since it is available on the WordPress plugin directory, it is also stored in a SVN repository. However, this GitHub project is the single source of truth for the plugin.


Planetary Science Archive (European Space Agency)

  • The European Space Agency’s Planetary Science Archive (PSA) is the central repository for all scientific and engineering data returned by ESA’s Solar System missions: currently Giotto, Huygens, Mars Express, Rosetta, SMART-1, ExoMars 2016, Chandrayaan-1, BepiColombo and Venus Express, as well as complementary ground-based observations. Future missions such as ExoMars 2022 and JUICE will also be hosted in the PSA. The PSA uses Planetary Data System standards as a baseline for the formatting and structure of all data contained within the archive… Learn more HERE.

NASA Planetary Science

  • For decades, NASA’s planetary science program has advanced the scientific understanding of the solar system in extraordinary ways, while pushing the limits of spacecraft and robotic engineering design and operations.

Gaia Archive

  • Gaia is a European space mission providing astrometry, photometry, and spectroscopy of more than 1000 million stars in the Milky Way. Also data for significant samples of extragalactic and Solar system objects is made available.
  • The Gaia Archive contains deduced positions, parallaxes, proper motions, radial velocities, and brightnesses. Complementary information on multiplicity, photometric variability, and astrophysical parameters is provided for a large fraction of sources.


NASA/IPAC Extragalactic Database

  • NED is a comprehensive database of multiwavelength data for extragalactic objects, providing a systematic, ongoing fusion of information integrated from hundreds of large sky surveys and tens of thousands of research publications. The contents and services span the entire observed spectrum from gamma rays through radio frequencies. As new observations are published, they are cross-identified or statistically associated with previous data and integrated into a unified database to simplify queries and retrieval. Seamless connectivity is also provided to data in NASA astrophysics mission archives (IRSAHEASARCMAST), to the astrophysics literature via ADS, and to other data centers around the world.
