The Milky Way Galaxy: A brief astronomical history

Aristotle (384-322 BC) wrote in Meteorologica that Anaxagoras (500-428 BC) and Democritus (460-370 BC) thought the Milky Way might consist of distant stars. Aristotle thought that the Milky Way was due to the ignition [that] takes place in the upper part of [Earth’s] atmosphere, in the region of the world which is continuous with heavenly motions . Other contemporaries of Aristotle argued against his idea about the Milky Way, including the argument that the galaxy’s parallax would be measurable if Aristotle’s idea was correct.

Recall, Abū al-Rayhān al-Bīrūnī (973-1048), a Persian astronomer and one of the most-respected Muslim scientists of his time, proposed that the Milky Way was a collection of countless fragments of the nature of nebulous stars.
