Now Saturn's rings have been known to be made of particles for hundreds of years , but these particles have so far escaped direct imaging. It is therefore particularly exciting that a preliminary hypothesis holds that these jagged shadows are silhouettes of transient groups of ring particles temporarily held close by their own gravity. ...

The diffraction image FWHM at 2.2 microns on the Gemini 8 m telescope is about 0.07". Consequently, a spectrograph with a 0.10" slit is essentially diffraction limited in the K band. ... Slit diffraction causes divergence in the spectral direction of rays through the slit in excess of the geometrical focal ratio; it can be thought of as focal ratio degradation speeding the beam in the spectral direction. ... A perfect image would have no phase coherence across the slit. ...

Telescope Jumps: One Cause is Found . ... One tries to take out the sag of the secondary cage as the telescope is pointed toward the zenith. The second component tries to take out changes in the secondary piston caused by temperature changes of the truss structure. ... Second, the jumps only occur when the temperature data causes motions of the piston which go in a direction opposite to the direction in which the sag component is driving the secondary. ... One has to wonder how this can occur. ...

... An analysis on new observational data taken with the MPFS and SCORPIO spectrographs indicates that we are dealing with the "galactic wind": the gas is blown above the galactic plane with the characteristic velocity of about 130km/s. The gas outflow is caused by a combined action of winds from the supernovae and young massive stars located in the galaxy's circumnuclear region. ... The most probable hypothesis is that the accretion of intergalactic gas clouds is feeding their star formation. ...
