Astronotes Armagh Planetarium's Stellar Blog! ... Saturn as you haven't seen it (Image credit: NASA/ESA) . This false colour image from the Hubble Space Telescope not only shows Saturn in an unfamiliar light, but displays some of the giant planet?s features. ... Viewing Saturn at this time not only allows us to see the famous rings almost edge on but also to observe both polar regions at once. There we see Saturn?s aurorae, analogous to Earth?s Northern lights and Southern Lights. ...

... We describe the software tool bspec which models the dispersion and diffraction of light in the HST Faint Object Spectrograph. ... The HST Faint Object Spectrograph (FOS) uses blazed, ruled gratings and detectors that are sensitive over wide wavelength ranges. ... The program bspec has been developed to model the dispersion and diffraction of light in the FOS with an accuracy sufficient for the estimation of scattered light contamination in observed FOS data. ... We run bspec as follows: . ...

... Light curves resulting from electron scattering absorption in this envelope were computed and compared with observed IBIS/ISGRI and BATSE light curves. ... Assuming approximately 10-6 solar mass/year for the rate of the WR-wind, the observed light curves and accretion luminosity can be re-produced (assuming Thomson scattering opacity in the ionized He-rich envelope). ... Reduced 2-values between the models and ISGRI light curves vs inclination, for different mass ratios and wind velocities. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...
