In 1869, based on observations of a solar eclipse proved the reality of the solar corona and found, . that it has a gaseous nature, found in the spectrum of the corona bright green line (as was shown in 1942, . This line belongs to 12-fold ionized atom of iron),
. In 1870 opened the reversing layer in the solar atmosphere - the gas, which formed the spectral absorption line. For the first time observed the spectrum of solar flares, has spectral studies of the chromosphere, prominences, sunspots. First applied to astronomy diffraction grating, measured with the help of the rotational speed of the Sun. Also studied the spectra of planets, comets, double stars and new. From well-known textbooks on astronomy: the Sun (The Sun, 1881), Manual of Astronomy (Manual of Astronomy, 1901). Jung died in Hanover on Jan. 3, 1908.
