This is a list of astronomical observatories ordered by name, along with initial dates of operation (where an accurate date is available) and location. The list also includes a final year of operation for many observatories that are no longer in operation. ... Nanjing Astronomical Instruments Research Centre: 1958 Nanjing, Jiangsu Province ...

This list of the largest optical reflecting telescopes with objective diameters of 3.0 metres (120 in) or greater is sorted by aperture, which is a measure of the light-gathering power and resolution of a reflecting telescope.The mirrors themselves can be larger than the aperture, and some telescopes may use aperture synthesis through interferometry. ...

This nomination comprises two astronomical observatories. The one at Kazan Federal University was founded in the early 19th century and the one at Engelhardt (pictured) in 1901. They were used to map the positions of stars and objects of the Solar System, as well as to develop astronomical instruments. National Park Kytalyk: Sakha: 2021

The zodiac is a belt-shaped region of the sky that extends approximately 8° north or south (as measured in celestial latitude) of the ecliptic, the apparent path of the Sun across the celestial sphere over the course of the year. The paths of the Moon and visible planets are within the belt of the zodiac.. In Western astrology, and formerly astronomy, the zodiac is divided into twelve …

A solar flare is an intense localized eruption of electromagnetic radiation in the Sun's atmosphere. Flares occur in active regions and are often, but not always, accompanied by coronal mass ejections, solar particle events, and other solar phenomena.The occurrence of solar flares varies with the 11-year solar cycle.. Solar flares are thought to occur when stored magnetic …

This listing is limited to those independent companies and subsidiaries notable enough to have their own articles in Wikipedia. Both going concerns and defunct firms are included, as well as firms that were part of the pharmaceutical industry at some time in their existence.

Engineering on an astronomical scale, or astronomical engineering, i.e., engineering involving operations with whole astronomical objects (planets, stars, etc.), is a known theme in science fiction, as well as a matter of recent scientific research and exploratory engineering.. In the Kardashev scale, Type II and Type III civilizations can harness energy on the required scale.

Astronomical interferometers can produce higher resolution astronomical images than any other type of telescope. At radio wavelengths, image resolutions of a few micro-arcseconds have been obtained, and image resolutions of a fractional milliarcsecond have been achieved at visible and infrared wavelengths.One simple layout of an astronomical interferometer is a parabolic …
