Ultraviolet astronomy is the observation of electromagnetic radiation at ultraviolet wavelengths between approximately 10 and 320 nanometres; shorter wavelengths—higher energy photons—are studied by X-ray astronomy and gamma-ray astronomy. [1] Ultraviolet light is not visible to the human eye. [2]
George Robert Carruthers (October 1, 1939 – December 26, 2020) [1] [2] was an American space physicist and engineer.Carruthers perfected a compact and very powerful ultraviolet camera/spectrograph for NASA to use when it launched Apollo 16 in 1972.
International Ultraviolet Explorer (IUE or Explorer 57, formerly SAS-D) [2] was the first space observatory primarily designed to take ultraviolet (UV) electromagnetic spectrum. The satellite was a collaborative project between NASA , the United Kingdom 's Science and Engineering Research Council (SERC, formerly UKSRC) and the European Space ...
The principal investigator and chief engineer of the Far Ultraviolet Camera/Spectrograph was Dr. George Robert Carruthers, who was working at the US Naval Research Lab. [9] In 1969, Dr. Carruthers was given a patent for "Image Converter for Detecting Electromagnetic Radiation Especially in Short Wave Lengths".
The terms chemical and heat rays were eventually dropped in favor of ultraviolet and infrared radiation, respectively. [1] 1895 Discovery of the ultraviolet radiation below 200 nm, named vacuum ultraviolet (later identified as photons) because it is strongly absorbed by air, by the German physicist Victor Schumann [2] 1895
The scientists discovered an object 15,000 light-years from Earth in the Scutum constellation. The object, dubbed GPM J1839−10, released radio waves every 22 minutes. The bursts of energy lasted ...
Ultraviolet radiation, also known as simply UV, is electromagnetic radiation of wavelengths of 10–400 nanometers, shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight , and constitutes about 10% of the total electromagnetic radiation output from the Sun.
