Solar High Resolution Studies . Back to . Solar Group . ... The study of photospheric "quiet" structures can have deep implications for a large variety of astrophysical topics, ranging from energy transport in astrophysical plasmas, to MHD problems in fluids with elevated Reynolds number. The wealth of structures and scales visible in the quiet solar photosphere is well exemplified in this white light movie, obtained at the Dunn Solar Telescope at the NSO/Sacramento Peak on Oct. ...

... Supernova 1987A in the Large Magellanic Cloud presents unprecedented opportunity to observe the evolution of a supernova at all wavelengths.

... The remote planet Pluto and its moon Charon orbit the Sun at a mean distance of almost 6,000 million kilometres, or nearly fourty times farther out than the Earth. During a recent investigation by an international group of astronomers [1], the best picture ever of Pluto and Charon [2] was secured with the European Space Agency's Faint Object Camera at the Hubble Space Telescope (HST). ... The new HST image was taken when Charon was near its maximum elongation from Pluto (0.9 arcseconds). ...
