. F IGURE . 6. Metallicities of the RR Lyrae stars as a function of apogalactic distance (a,b,c) and maximum distance from the Galactic plane (d,e,f). The straight lines are least-squares fits.The five most distant stars in each panel (in boxes) were excluded from our calculations.

... We have measured this "redshift" for the pink black holes, and allowed for it in our calculations. ... We see this effect in the emission from gas around these pink black holes, but it is far too small an effect to account for the pinkness. Thus the swirling motions of gas around or into the black holes cannot produc the colour. ... At first we thought that these things were normal blue black holes hidden behind clouds of interstellar dust, that absorbed the blue light and made them appear pink. ...

News & Views There seems to be something very healthy about astronomical research when, under the same cover, an event which took place in 1333 AD (Leonid bursts as a resonance meteoroid component from Comet Temple/Tuttle) is discussed followed by a paper on how we might more effectively search for extraterrestrial intelligence (in the optical). In this issue we also have a further paper on young clusters (Praesepe) and the low end of the stellar mass function (see IAJ , 1999, 26(1), 17). ...

... This document and the attached postscript figure document an analysis that I did to determine the optimum midpoint and required ranges for both the rotator and azimuth for the 2.5 M telescope. ... I simulate a series of drift scans on the sky for tracks that cover the northern survey area. These tracks cover the range in survey latitude of -60 to +60 degrees, spaced by 10 degrees. ... Along each track the azimuth, elevation, and position angle of the CCD is computed at 1 minute intervals. ...

... Currently, there is very little information on comets which are active beyond the orbit of Jupiter. ... Previous observations conducted by our team with the SAO RAS 6-m telescope showed that some of these comets have extended tails dissimilar to the tails of comets forming at close heliocentric distances. ... We for the first time measured the linear polarization of scattered emission for the two distant comets C/2010 S1 (LINEAR) and C/2010 R1 (LINEAR) at heliocentric distances of 5.9-7.0 au. ...

This is a copy of a Press Release from E.S.O. Eight years after the passage of Comet Halley in early 1986, astronomers at the European Southern Observatory have succeeded in obtaining an image of this famous object at a distance of no less than 2,820 million km from the Sun. ... The image shows the 6 x 15 km avocado-shaped nucleus as an extremely faint point of light without any surrounding dust cloud. ... This observation was made with the ESO 3.58 metre New Technology Telescope (NTT). ...
