In 2002 November the Earth will pass near the trails released at the 1866 and 1767 returns, i.e. 4 revolutions and 7 revolutions of the comet ago. The Earth's passage right through the centre of trails is associated with the most spectacular meteor displays (studies show that, as well as how close to the centre of the trail you are, the strength of the display also depends on how far along a trail's length you are). ...

... We present a comparison of the surface density of young stars (неБ‹†) and dust surface density (неdust) across NGC 346 (N66) in 115 independent pixels of 6 ц— 6 pc2. ... We convert неdust to gas surface density (неgas) and неБ‹† to star formation rate (SFR) surface densities (неSFR), using simple assumptions for the gas-to-dust mass ratio and the duration of star formation. ... On small scales the неSFR derived using Hн± systematically underestimates the count-based неSFR, by up to a factor of 10. ...

... From the peculiar shape of the light curve in the visible spectral region (a long phase interval of light constancy was observed by Hensberge et al. in 1981 ), HD 56022 had been expected to show unambiguously the nonequatorial symmetry of its surface brightness distribution. However, analysis of the light curve has yielded a possible equatorial position of a spot. ... A solution seems only possible, if the light constancy over the long phase interval in the visible is not observed in the UV. ...
