published in 1890 a widely read paper that included Very's Moon observations, but for unknown reasons omitted his name from the list of contributors. In 1891, Very published his own paper, "Distribution of the Moon's Heat," which also included measurements taken during a
lunar eclipse.
Infrared observations by Langley and Very, published in 1890, were used to make the first calculations of the
greenhouse effect
The greenhouse effect is a process that occurs when energy from a planet's host star goes through the planet's atmosphere and heats the planet's surface, but greenhouse gases in the atmosphere prevent some of the heat from returning directly ...
