The high-redshift radio-loud quasar PKS 2126-158 is found to have a large number of red galaxies in close apparent proximity.We use the Gemini Multi-Object Spectrograph (GMOS) on Gemini South to obtain optical spectra for a large fraction of these sources. We show that there is a group of galaxies at z 0.66, coincident with a metal-line absorption system seen in the quasar s optical spectrum. ... All confirmed members exhibit early-type galaxy spectra, a rare situation for a MgII absorbing system. ...

... The concerns here are similar to those for observing bright targets; saturation and blooming of the bright companion PSF must not impact the faint target. Also, one may need to consider subtracting the PSF of the bright object, and effects which limit the accuracy of that subtraction. If the bright companion will saturate and bloom, it will be necessary to rotate the CCD so that blooming along the CCD columns does not obliterate the faint target. ...

... The planets are still growing slowly as comets and meteoroids collide with them. ... In the 1950s, American astronomer Fred Whipple suggested that comets are dirty snowballs: clumps of ice mixed with interplanetary dust. ... For most of its orbit, a comet remains far from the Sun, little more than the dirty snowball that it is -- what is usually called a bare nucleus. ... As Comet Hyakutake approached the Sun, jets of dust erupted from the Sun-facing side of its nucleus. ...

... On the base of laboratory simulations (on rotating shallow water) of the formation of spiral arms in galactic gaseous disks, the existence of giant anticyclones in them was predicted. Numerical simulations shown that the vortex structures arise on a linear stage of spiral arms formation simultaneously with the latter. ... Thus second giants structures, after spiral arms, in spiral galactic disks are discovered. ...
