... 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). ...

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. ...

... ROTATION CURVE: When studying spiral galaxies it is invariably found that the stellar rotational velocity in the disk remains constant, or "flat", with increasing distance away from the galactic center. ... The rotation speed of the stars in galaxies is found NOT to decrease with increasing distance from the galactic center (see emission lines in the spectrum), implying that the overall mass distribution of the galaxy is different from the light distribution. ...

We have obtained simultaneous high resolution H alpha and Na I D spectra of five dwarf M stars that span a wide range in chromospheric activity level. ... However, the H alpha line systematically indicates a value for the mass loading at the onset of the Transition Region and the location of T_min that is 0.4 dex lower in column mass density than that indicated by NaI D. Therefore, the profile of both lines cannot be simultaneously well fit for all but one of our stars. ...

... We can help students grasp the significance of Hubble's extremely keen eye, and learn a bit about angles and math in the process, with the following in-class activity. ... Looking through binoculars or telescopes allows us to magnify a small section of the sky. To measure sizes or distances in that small section, astronomers divide a degree into 60 smaller pieces called arcminutes, and further subdivide minutes into 60 smaller sections called arcseconds. ... 30 feet = . ... 36 seconds . ...
