Charles Augustus Young (December 15, 1834 – January 4, 1908) one of the foremost solar spectroscopist astronomers in the United States, died of pneumonia after a brief illness, at his home in Hanover, New Hampshire, on 4 January 1908.
In 1869 the astronomers Charles Augustus Young and William Harkness independently observed a novel green emission line in the Sun's corona during an eclipse. This "new" element was incorrectly named coronium, as it was only found in the corona. It was not until the 1930s that Walter Grotrian and Bengt Edlén discovered that the spectral line at 530.3 nm was due to highly ionized iron (Fe 13+ ). Other unusual lines in the coronal spectrum are also caused by highly charged ions, such as nickel and calcium, the high ionization being due to the extreme temperature of the solar corona.

Many years later in 1927, when Henry Norris Russell, Raymond Smith Dugan and John Quincy Stewart wrote their own two-volume textbook, they entitled it Astronomy: A Revision of Young’s Manual of Astronomy.
He studied astronomy at Princeton University, obtaining his B.A. In 1897 and his doctorate in 1899, studying under Charles Augustus Young.

Loomis Observatory

Young's name is inscribed on the Loomis Observatory.
An inscription on the historic marker reads: "Elias Loomis and Charles Augustus Young worked in this Observatory, built in 1838, the third to be erected in the United States, the second oldest standing (1926). "

Martian canal

In 1889, American astronomer Charles A. Young reported that Schiaparelli's canal discovery of 1877 had been confirmed in 1881, though new canals had appeared where there had not been any before, prompting "very important and perplexing" questions as to their origin.

Coronium

During the total solar eclipse of 7 August 1869, a green emission line of wavelength 530.3 nm was independently observed by Charles Augustus Young (1834–1908) and William Harkness (1837–1903) in the coronal spectrum.
