Solar prominences

Advancements in astronomical photography allowed for the detailed capture of solar phenomena. This included solar prominences which are gouts of flame around the edge of the sun during a total eclipse. This was the first astronomical discovery made as a result of photography, and required de la Rue to quickly travel to Spain.
