Piazzi’s Flying Star” & Stellar Parallax

Western Slope Skies

Throughout history, a belief in the “fixed” and changeless stars was held by many cultures. But at the beginning of the 19th Century, Italian astronomer Giuseppe Piazzi repeatedly measured the position of a star called 61 Cygni. Piazzi’s work overturned such long-held beliefs and led to research that ultimately allowed astronomers to accurately measure the scale of the Milky Way Galaxy and to learn of our location within it.
