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 ."
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. 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]
His work is widely published in the media. [2] [3]On 10 April 2009, NASA featured one of his images as its "Astronomy Picture of the Day". [4] An October 2011 image he took of the 2.6-short-ton (2.4 t) defunct German telescope ROSAT was published by various media outlets, including the Washington Post, The New York Times, and Fox News.

Picture of the day. Halos are optical phenomena that appear near or around the Sun or Moon, and sometimes near other strong light sources such as street lights. There are many types of halos, but they are mostly caused by ice crystals in cold cirrus clouds located high (5-10 km, or 3-6 miles) in the upper troposphere. The particular shape and ...
O'Donnell has been awarded with the Astronomy Picture of the Day (APOD) by NASA twice. The first was published on the APOD website on March 20, 2015, entitled "Sunshine, Earthshine". [11] "Earth Shine" depicts the moon 14 hours after perigee, the point where the moon is closest to the earth. [12]
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).
