Joseph Louis Gay-Lussac, French physicist and chemist, 1848. Artist: Unknown
Joseph Louis Gay-Lussac, French physicist and chemist, 1848. Gay-Lussac (1778-1850) made balloon ascents to investigate terrestrial magnetism and composition and characteristics of the atmosphere at different altitudes. He determined that the same volume of any gas will expand equally in response to the same increase in temperature. Amongst his achievements in chemistry were recognising iodine as a chemical element, and being one of the discoverers of the element boron.

Comet Shoemaker-Levy colliding with Jupiter, 20 July 1994. Artist: Unknown
Comet Shoemaker-Levy colliding with Jupiter, 20 July 1994. Between 16 and 22 July 1994, some 20 fragments of Comet Shoemaker-Levy 9 struck the atmosphere of Jupiter, creating disturbances which remained visible to astronomers for several days. The largest impact released energy equivalent to an estimated 6 million megatons of TNT and left a mark in the Jovian atmosphere larger than the diameter of the Earth. Astronomers believe that Jupiter plays a vital role in intercepting cosmic debris that might otherwise have reached the inner solar system, enabling the unbroken development of life on Earth to have occurred.
