There is a lot of astrology in the astronomy tag lately, and I am growing ever more appreciative of Tumblr Savior.
Tumblr users like to play a little fast and loose with the definitions of words sometimes, so I’m going to outline the difference between astrology and astronomy:
Astrology is the idea that astronomical events, such as the position of a planet, affect human life. Many cultures have developed their own different systems of divination based on the stars.
Astronomy is an area of scientific discipline that studies objects in space using physics, math, and chemistry as tools.
Both share a common origin and a common prefix, but they are distinct concepts. One is considered a valid science backed by evidence, the other is not. That’s all I’ll say on that subject.
Your beliefs are your own business, but astrology and astronomy are not interchangeable words.
Since I have no idea how to tackle the subject of seeing pictures of galaxies and whatnot tagged “astroid,” I’m done policing the tags for the day!
