Astronomy is a science involving the observation and explanation of events occurring outside Earth and its atmosphere. It studies the origins, evolution, physical and chemical properties of objects that can be observed in the sky (and are outside the earth), as well as the processes involving them.
From its earliest roots in astrometry, astronomy has evolved into various fields of study within observational astronomy and theoretical astrophysics, but it is one of the few sciences where amateurs can still play an active role.
