The "chemical rays" found by him were afterwards called ultraviolet radiation. [ 7 ] [ 8 ] [ 9 ] Some of Ritter's researches were acknowledged as important scientific contributions, but he also claimed the discovery of many phenomena that were not confirmed by other researchers.
A false color photograph with ultraviolet radiation (335-365nm) mapped to the blue channel, green light (500-600nm) to the green channel and infrared radiation (720-850nm) to the red channel. Ultraviolet photography is a photographic process of recording images by using radiation from the ultraviolet (UV) spectrum only. Images taken with ...
A major piece of evidence for the presence of dark matter in the Universe, discovered by Vera Rubin from observations of galactic rotation curves in the 1970s. Stars luminosity Henrietta Swan Leavitt was an American astronomer who discovered the relation between the luminosity and the period of Cepheid variable stars at the beginning of 20th ...
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]
New research from the University of California, San Diego could solve a mystery that scientists have puzzled over for several years.
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 dull halogen light. The spinning glass plate. The humming that terminates in a “BEEP.” Today the sights, sounds, and smells of the microwave oven are immediately familiar to most Americans.
Doritos are a revered snack for many. Now, scientists have found one of the ingredients in the triangle-shaped tasty tortilla chips has a superpower – it can make the skin of mice transparent.
