Abstract:
A blackbody radiation source includes an insulated enclosure having a viewing aperture defining a line of sight through the wall of the enclosure. A heat sink, preferably a pool of liquid nitrogen, is located within the insulated enclosure. There is a viewing surface in thermal contact with the heat sink but having an unobstructed view through the viewing aperture. The viewing surface is inclined to the line of sight through the viewing aperture. A sensor is calibrated by placing the sensor in facing relation to the aperture and measuring an output black body signal of the sensor. The viewing surface may be radiatively heated concurrently with the measuring to produce a higher equivalent radiometric temperature.

Charon was discovered by United States Naval Observatory astronomer James Christy, using the 1.55-meter telescope at NOFS, and was formally announced to the world via the International Astronomical Union on July 7, 1978. Subsequent observations of Pluto determined that the bulge was due to a smaller

How our view of Pluto and its moons has transformed through the decades
scientists used data collected by the Hubble Space Telescope and other observatories to learn more about Pluto and hunt for moons around the tiny planet. The small planet's largest moon Charon was discovered in 1978 by U.S. Naval Observatory astronomer James Christy peering through a telescope in Arizona.
Spencer, it is fair to say, does not have a sparkling reputation among climate scientists, not least because he and UAH colleague James Christy previously maintained that their data showed no warming in Earth's atmosphere, a claim long embraced by deniers but one that Spencer and Christy now concede
