Facts about Astronomy

Astronomy

In ancient Greece and other early civilizations, astronomy consisted largely of astrometry, measuring positions of stars and planets in the sky.

Astronomy

Astronomy is one of the oldest sciences, with a scientific methodology existing at the time of Ancient Greece and advanced observation techniques possibly much earlier as seen in the study of archaeoastronomy.

Astronomy

Astronomy (Greek: ?????????? = ?????? + ?????, astronomia = astron + nomos, literally, "law of the stars") is the science of celestial phenomena that originate outside Earth's atmosphere.

Astronomy

The emergence of astronomy as a science following the scientific method is very important to the development of science in general.

Astronomy

Motions and positions of objects are now more easily determined, and modern astronomy is more concerned with observing and understanding the actual physical nature of celestial objects.

Astronomy

Observational astronomy was mostly stagnant in medieval Europe, but flourished in the Iranian world and other parts of Islamic realm.

Astronomy

Powerful gamma rays can, however be detected by the large air showers they produce, and the study of cosmic rays can also be regarded as a branch of astronomy.

Astronomy

Astronomy is one of the few sciences where amateurs can still play an active role, especially in the discovery and monitoring of transient phenomena.

Astronomy

Optical and radio astronomy can be performed with ground-based observatories, because the atmosphere is transparent at the wavelengths being detected.

Astronomy

The ancient Greeks made important contributions to astronomy, among them the definition of the magnitude system.

Astronomy

Observational astronomy is concerned mostly with acquiring data, which involves building and maintaining instruments and processing the resulting information; this branch is at times referred to as "astrometry" or simply as "astronomy."

Astronomy

Categorization by the region of space under study (for example, Galactic astronomy, Planetary Sciences); by subject, such as star formation or cosmology; or by the method used for obtaining information.
