Astronomy Picture of the Day (APOD) is a website provided by NASA and Michigan Technological University (MTU). It reads: "Each day a different image or photograph of our universe is featured, along with a brief explanation written by a professional astronomer ."
Astrometry, the science of spherical astronomy, is concerned with precise measurements of the location of celestial bodies in the celestial sphere and their kinematics relative to a reference frame on the celestial sphere. [8] In principle, astrometry can involve such measurements of planets, stars, black holes and galaxies to any celestial ...
Astrometry. Professional setups are using astrometric solving to measure accurately the position of minor planets or comets to calculate orbital parameters. [5] Telescope Mount pointing. Astrometric solving is used for pointing the telescope mount accurately by syncing it to the celestial position of the image center. [6]
It relies on the mathematical methods of spherical trigonometry and the measurements of astrometry. This is the oldest branch of astronomy and dates back to antiquity. Observations of celestial objects have been, and continue to be, important for religious and astrological purposes, as well as for timekeeping and navigation. The science of ...
A significant expansion of the catalog, Guide Star Catalog II, was published in 2008. The Guide Star Catalog II (GSC-II) was compiled by the Catalog and Surveys branch of the Space Telescope Science Institute and the astrometry team of the Astronomical Observatory of Torino (Italy). It has entries for 945,592,683 stars, and has positions ...
Astrometry is a branch of astronomy that involves precise measurements of the positions and movements of stars and other celestial bodies. It provides the kinematics and physical origin of the Solar System and this galaxy , the Milky Way .
His photos have been published several times on the websites of NASA and the ESA. [ 7 ] Having set up an observatory behind his house in Byron Bay, O'Donnell began submitting his astrophotographs to a variety of websites, [ 3 ] with some being published by NASA, ESA, Time , and National Geographic .

Full-sky Astrometric Mapping Explorer (or FAME) Full-sky Astrometric Mapping Explorer (or FAME) was a NASA proposed astrometric satellite designed to determine with unprecedented accuracy the positions, distances, and motions of 40 million stars within our galactic neighborhood (distances by stellar parallax possible).
