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 ."
The six volumes in the fundamental catalogue series are as follows: The Fundamental-Catalog (FC) was compiled by Auwers and published in two volumes. The first volume, published in 1879, contains 539 stars.
This print, published in Richard Blome's "The Gentleman's Recreation" (1686) shows the diverse ways in which cosmography can be applied Celestial cartography , [ 1 ] uranography , [ 2 ] [ 3 ] astrography or star cartography [ citation needed ] is the aspect of astronomy and branch of cartography concerned with mapping stars , galaxies , and ...
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 .
Astrometry is the study of the positions, distances between, and motions of astronomical objects. Subcategories This category has the following 10 subcategories, out of 10 total.
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. 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]
