... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...

... Imaging of the core of the OMC-1 region using NICMOS camera 2 through the F212N and F215N filters shows a wide variety of interesting structure on scales of 0.2" at a very high dynamic range (Stolovy et al. ... The application of image restoration techniques, including multi-channel variants of the Richardson-Lucy technique, offers the chance to enhance structure on the finest scales and also to suppress the prominent and richly structured point-spread functions of the many bright stars in the...

... The main field of my investigations is stellar spectrophotometry. As a result of scientific activity of our group spectrophotometric catalog was created including energy distribution data on 900 stars in the range 3200-7600AA and 250 stars in the range 6000-10800AA (Voloshina et al., Spectrophotometry of Bright Stars, ed. I.N.Glushneva, 1982, Moscow, Nauka, in Russian). ...

... The NOTE element is designed for use as admonishments such as notes, cautions or warnings, as commonly used in technical documentation. The CLASS attribute specifies the type of the element and is typically associated with different graphics such as a road traffic warning sign. ... The class names: NOTE, CAUTION and WARNING are recommended for standard admonishments. In the absence of the CLASS attribute, a NOTE element is typically rendered indented, without an accompanying graphic. ...

... This is usually defined as the direction pointing toward the center of the primary body. ... NODE: The place where the plane of one orbit crosses the plane of another. ... ORBITAL PLANE: The flat surface that would result if every point on the orbit of a body was connected to the center of its primary. ... PENUMBRA: The edge of the primary body's shadow. ... PERIOD : The time required for one body to orbit the primary body. ... PROBE: A vessel designed to pass and observe an astronomical object. ...
