Introducing Comet ISON . ... Credit Copyright: Ligustri Rolando Explanation: Could this dim spot brighten into one of the brightest comets ever? ... Sky enthusiasts the world over are all abuzz, though, from the more optimistic speculations -- that the newly discovered C/2012 S1 (ISON) could develop a spectacular tail or briefly approach the brightness of the full Moon toward the end of 2013. Comet ISON currently is very faint but is just visible at magnitude 18 in the above image. ...

... Content Model: Optional list header (LH), followed by one or more terms (DT) and definitions (DD). A definition list is a list of terms and corresponding definitions. Definition lists are typically formatted with the term on the left with the definition following on the right or on the next line. ... The definition list element can take the COMPACT attribute, which suggests that a compact rendering be used, and is appropriate if the list elements are small and/or the entire list is large. ...

Detected Supernovae . The search have produced till now the detections of 4 SNe. ... This result highlights the power of infrared monitoring in detecting Obscured SNe and indicates that optical surveys are probably missing a significant fraction of SNe, especially in obscured systems such as starburst galaxies. ... In Fig. we show the archival SOFI image of NGC3256 (left) and the first image obtained in 2001 (right) where SN2001db has been detected. ...

... A technique allowing automatic representation by a relatively small number of independent parameters based on the principal component analysis of data sequences is presented. ... In recent years the spectrum of observed astronomical data can be characterized as greatly varied. ... In this instance, the problem of initial description and classification of newly-observed data becomes most urgent, especially if there is a lack of preliminary observational material and theoretical expectations. ...

... The width of hydrogen lines is known to depend on the pressure in the photosphere, and then on the luminosity and effective temperature of the star. We have studied this dependence using the spectra of normal B stars from the databases by Jacoby et al., ... The resolution of Jacoby spectra (4.5А) coincides with the resolution of our BTA/UAGS spectra (4.4A). ... Dependence of full width FWZI of hydrogen lines on star spectral type and luminosity class. ...

... The variability of the spectrum of the optical component of the IR-source IRAS01005+7910 was discovered for the first time in the BTA spectra [1]. ... The spectral features include absorptions that form in near-photospheric layers, narrow envelope emissions, and emission-absorption profiles that form in photosphere-to-envelope transition layers (the wind). ...

. ArtistтАЩs impression of an active volcano on Venus. Results from a long-term study of Venus find evidence of a clear injection of sulfur dioxide into its upper atmosphere. One possible interpretation is that volcanic activity increased the sulfur dioxide component of the upper atmosphere, although an alternative is that a change in atmospheric circulation dredged up the gas. // Credits: ESA/AOES
