<br/><br/> "In earlier centuries, astronomers could only watch as the silhouette of Venus marched across the Sun's face. But for the 1874 and 1882 transits, they could take pictures too." (SKY & TELESCOPE) This article describes the 19th century transits of Venus across the Sun's disk and explains what astronomers learned from these infrequent astronomical events.
