First edition of Ångström's early work on thermometrical phenomena.Ångström was one of the early formulators of the science of modern spectroscopy he wrote extensively on terrestrial magnetism, the conduction of heat, and especially spectroscopy. He published a monumental map of the normal solar spectrum that expressed the length of light waves in units of one ten-millionth of a millimeter, a unit of length now known as the angstrom. He discovered that hydrogen is present in the sun's atmosphere, and he was the first to examine the spectrum of the aurora borealis.

First edition. In this paper Ångström deduces the mean period of Halley's Comet by a statistical approach. From his analysis he discovered that the average time between perihelions was 76.93 years and found that thsi period varied in a cyclical manner.Ångström was one of the early formulators of the science of modern spectroscopy" he wrote extensively on terrestrial magnetism, the conduction of heat, and especially spectroscopy. He published a monumental map of the normal solar spectrum that expressed the length of light waves in units of one ten-millionth of a millimeter, a unit of length now known as the angstrom.

First appearance in German of Ångström's famous paper in which he announced the discovery of hydrogen in the atmosphere of the sun and in which he also confirmed the probable existence of of other elements there. The paper appeared in ""Oefversigt af K. Vet. Acad. Förhandl."" in 1861. The German paper here is expanded. At the same time it was translated into English and publishe as ""On the Fraunhofer Lines Visible in the Solar Spectrum"".Ångström was one of the early formulators of the science of modern spectroscopy" he wrote extensively on terrestrial magnetism, the conduction of heat, and especially spectroscopy. He published a monumental map of the normal solar spectrum that expressed the length of light waves in units of one ten-millionth of a millimeter, a unit of length now known as the angstrom.
