Anders is famous because he is the founder of spectroscopy.
Spectroscopy is the branch of science concerned with the investigation and measurement of spectra produced when matter interacts with or emits electromagnetic radiation
He went to the Stockholm Observatory to get experience in practical astronomical work, and was appointed keeper of the Uppsala Astronomical Observatory the next year.
In February, 1853, Ångström presented his “Optiska undersökninger” (“Optical Researches”) before the Stockholm Academy of Science.
He was the first person to examine the spectrum of the aurora borealis.
he found and measured the bright line in its yellow/green area; but he mistakenly said this same line is also to be seen in the zodiacal light.
He proved the sun's atmosphere contains hydrogen and a few other elements with his combination of the spectroscope and photography.
