They help answer some of the most frequently asked questions sent to the ROG astronomers, including 'naming a star', sunrise and sunset calculators and terrestial coordinates. We also provide links to the some of the major astronomical organizations such as PPARC, ESA and NASA.

  • HM Nautical Almanac
    In collaboration with the Royal Observatory Greenwich, this site provides celestial data to the public, including a sunrise and sunset time calculator, visibility predictions for the new crescent Moon, maps of forthcoming eclipses and information on UK public holidays.
  • SunHeight
    A site that can compute height and azimuth and the rise and set of solar system bodies at anytime and from anywhere on earth.
  • Getty Thesarus of Geographic Names
    Information on terrestrial coordinates - latitude and longitude. (Please note: the Royal Observatory is unable to provide information on these)
  • Night sky news - National Schools Observatory
    Notes on what you can see in the night sky this month, including phases of the moon, map of the current night sky and this month's highlights.
