optical astronomy

(op -tă-kăl) The study of astronomical objects using radiation with wavelengths from about 300 to 900 nanometers. These wavelengths can pass through the Earth's atmosphere so that observations are possible from the ground. The human eye is sensitive to most of this waveband. See also light; reflecting telescope; refracting telescope.

This exceptional technological ensemble illustrates the transition from traditional optical astronomy to radio astronomy (1940s to 1960s), which led to radical changes in the understanding of the universe.

Through communal living, they can be supported to build solar and wind farms and since they have one of the best astronomical sites, they can partner with investors to build an optical astronomy observatory that will attract tourism to the ASAL areas.Income from these investments would go to dispensing capital expenditure as well as for building community resilience.

"I've explored Pluto and the distant reaches of the universe from the comfort of my living room," said Tod Lauer, an astronomer with the National Optical Astronomy Observatory in Arizona.
Wolff (former director of the Kitt peak National Observatory and the National Optical Astronomy Observatory) deftly explores these questions and more by taking a look at the search for life and new planets, the mysteries of dark matter and dark energy, and building bigger and better telescopes.
that's the end of the story," says Joan Najita, an astrophysicist at the National Optical Astronomy Observatory in Tucson.
"Our observations provide a first glimpse at protostars that have just begun to 'glow' at far-infrared wavelengths," said paper coauthor Elise Furlan, a postdoctoral research associate at the National Optical Astronomy Observatory in Tucson, Ariz.
It also takes a financial toll: The federally funded National Optical Astronomy Observatory (NOAO) reports that poorly-aimed, unshielded outdoor lights waste $2 billion (17.4 billion kilowatt-hours) of energy in the U.S.
"The discovery is surprising because previous surveys had not found galaxies this bright so early in the history of the universe," said Mark Dickinson of the National Optical Astronomy Observatory in Tucson, Arizona.
This is strongly motivated by the dark and clear skies in Sutherland for optical astronomy, the vast desolate plains of the Karoo for frequency interference-less radio astronomy, and the urge to develop world class astronomical facilities in order to maintain South African astronomy as world class.
