'''ستورپوهنه''' د (ستورو قانون) ده. ستورپوهنه يو داسيې ساينسي پوهه ده، د كومې په واسطه چې د زمكې څخه بهر پېښېدونكو پېښو څېړنه كېږي. پدې كې پر [[اسمان]] كې د ليدونكيو اجسامو پېل، ارتقاء او طبعي او كېمياوي ځانګړتياو څېړنه كېږي، چې دې څېړنې ته په انګرېزۍ كې (Astronomy) وايي.
'''ستورپوهنه''' (چې اکثراً د '''آسټروفيزيکس''' په نامه هم يادېږي) د اسماني شيانو لکه ستوري، سيارې، لکۍ داره ستوري او د کهکشانونو په هکله د څېړنې يوه ساينسي زده کړه ده. په دې زده کړه کې د اسماني شيانو او د هغه شيانو چې د ځمکې د اتموسفير نه دباندې دي، د هغو د پېدايښت او اصل په هکله څېړنې او پېژندنه ترسره کېږي. (such as the [[Cosmic microwave background radiation|cosmic background radiation]]). It is concerned with the evolution, [[physics]], [[chemistry]], [[meteorology]], and [[motion (physics)|motion]] of celestial objects, as well as the [[physical cosmology|formation and development of the universe]].
Astronomy is one of the oldest sciences. Astronomers of early civilizations performed methodical observations of the night sky, and astronomical artifacts have been found from much earlier periods. However, the invention of the [[telescope]] was required before astronomy was able to develop into a modern science.
Since the 20th century, the field of professional astronomy split into [[observational astronomy|observational]] and [[theoretical astrophysics|theoretical]] branches. Observational astronomy is focused on acquiring and analyzing data, mainly using basic principles of [[physics]]. Theoretical astronomy is oriented towards the development of computer or analytical models to describe astronomical objects and phenomena. The two fields complement each other, with theoretical astronomy seeking to explain the observational results, and observations being used to confirm theoretical results.
Historically, [[amateur astronomy|amateur astronomers]] have contributed to many important astronomical discoveries, and astronomy is one of the few sciences where amateurs can still play an active role, especially in the discovery and observation of transient phenomena.
Modern astronomy is not to be confused with [[astrology]], the belief system that claims that human affairs are correlated with the positions of celestial objects. Although the [[Astrology and astronomy|two fields]] share a common origin, most thinkers in both fields believe they are now distinct.<ref name="new cosmos">{{cite book | author=Albrecht Unsöld | coauthors=Bodo Baschek, W.D.
