High energy astronomy is the study of astronomical objects that release EM radiation of highly energetic wavelengths. It includes X-ray astronomy, gamma-ray astronomy, and extreme UV astronomy, as well as studies of neutrinos and cosmic rays. The physical study of these phenomena is referred to...
Galileo Galilei was the first person known to have turned a telescope to the heavens and to record what he saw. Since that time, observational astronomy has made steady advances with each improvement in telescope technology. A traditional division of observational astronomy is given by the...

Extreme Ultraviolet Explorer (EUVE) was a space telescope for ultraviolet (UV) astronomy, launched on June 7, 1992. With instruments for UV radiation between wavelengths of 7 and 76 nm, the EUVE was the first satellite mission especially for the short-wave ...
At launch, the announced purpose of Salyut was to test the elements of the systems of a space station and to conduct scientific research and experiments. The craft was described as being 20 m in length, 4 m in maximum ... The mission would measure: * Atmospheric density, temperature and pressure as functions of altitude, latitude and time. * Definition of the planetary surface and its properties. * Chemical composition of the low atmosphere and the planetary surface. * Ionospheric data ...

The song details types of energy transmitted across time and space. The first line mentions “ultraviolet..radio light..to your solar system…” indicating someone or something is attempting to communicate across the galaxy. In astronomy, UV light is emitted by very hot ... Pittendreigh has been a life-long active amateur astronomer and wrote several articles about astronomy in the United States and the United Kingdom. His work, “Pittendreigh’s Law of Planetary Motion” was published in Sky and Telescope magazine in February 1994. During ...
Astrosat is India’s first dedicated astronomy satellite and is scheduled to launch on board the PSLV in 2011 After the success of the satellite-borne Indian X-ray Astronomy Experiment (IXAE), which was launched in 1996, the Indian Space Research Organization (ISRO) ...
Ultraviolet astronomy is generally used to refer to observations 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. Light at these wavelengths is absorbed by ...
Space Telescope Science Institute (STScI) is the science operations center for the Hubble Space Telescope (HST; in orbit since 1990) and for the James Webb Space Telescope (JWST; scheduled to be launched in 2014). STScI is located on the Johns ...
Cosmic Origins Spectrograph (COS) is a science instrument that was installed on the Hubble Space Telescope during Servicing Mission 4 (STS-125) in May 2009. It is designed for ultraviolet (115-320 nm) spectroscopy of faint point sources with a resolving power ...
Stern has over extensive experience in instrument development, with a strong concentration in ultraviolet technologies. Stern is a principal investigator (PI) in NASA’s UV sounding rocket program, and was the project scientist on a Shuttle-deployable SPARTAN astronomical satellite. He was ...
X-ray telescopes can use a variety of different designs to image X-rays. The most common methods used in X-ray telescopes are grazing incidence mirrors and coded apertures. The limitations of X-ray optics result in much narrower fields of view than ...
There are several hypotheses for how solar variations may affect Earth. Some variations, such as changes in the size of the Sun, are presently only of interest in the field of astronomy. Changes in total irradiance * Total solar irradiance ... William Hyde Wollaston in 1802 and Joseph von Fraunhofer in 1814 described the dark lines within the solar spectrum. Later, Gustav Kirchhoff explained the lines by atomic absorption or emission, which allowed the lines to be used for the identification ...
