His most important work was in measuring the temperature of the surfaces of the Moon and other planets using a bolometer. Samuel Pierpont Langley published in 1890 a widely read paper on the Moon observations, but for unknown reasons omitted Very's name from the list of authors. In 1891, Very published his own paper about the "Distribution of the Moon's Heat," which also included measurements taken during a lunar eclipse. Temperature is the physical property of a system which underlies the common notions of hot and cold; the material with the higher temperature is said to be hotter. ...
