. 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

... Bad Astronomy . ... Bitesize Astronomy . ... Last week's Snack talked about how black holes can affect the environment around them in such a way as to be very bright . ... It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...

Where and how are we looking for evidence of life? ... Because the universe is an immense place, it makes sense to search for evidence of life in more than one way. In addition to focusing on what we know about life on Earth, especially in extreme environments, astrobiology currently comprises three basic types of searches in space, each employing different technologies, looking in different places, and expecting to find different kinds of data: . ... The search types ? ... Extrasolar Planets vs. ...

I review recent developments in the study of interstellar extinction, specifically findings on the wavelength-dependence of the extinction curve both within the Milky Way and toward nearby galaxies; And how these affect distance determinations to the Galactic centre, and in the context of HubbleтАЩs constant, and toward Type Ia supernovae. ...

... Recent studies indicate that stars are most likely forming within the binary and multiple systems. ... During several years we are conducting the observations of such multiple stellar systems at the BTA telescope in order to find their companions and study the properties therein. ... This star is interesting in that it may be a dynamically unstable multiple star, meaning that over time, such systems will split into individual stars. ... A bright component is a very tight spectroscopic binary star. ...

... The Impact of HST on European Astronomy . ... These range from the study of nearby planets, the processes of star and planet formation, the stellar and interstellar components of galaxies, the discovery that most, if not all, galactic nuclei harbor a massive black hole that profoundly affects their evolution, to the realisation that the universe as a whole is undergoing acceleration as a result of a yet unknown form of dark energy . ... Formation, structure and evolution of galaxies . ...

... The main topics of the Conference were: 1. ... Asteroid-comet hazard (origin and dynamic evolution of objects approaching the Earth, observations, physical properties, cataloguing, data bases, estimation of collision probability with the Earth and other bodies). ... 5) In this connection the problem of concluding the international political agreement within the frames of UN about common active counteractions to the bodies on the orbits leading to collisions with the Earth is urgent. ...

... The circumnuclear GASEOUS disks are often decoupled from the circumnuclear stellar disks and are even stronger inclined to the outer disk planes; in fact, we have found a considerable `population' of inner polar rings. Inner gas polar rings are found as in spiral galaxies with the massive outer gas disks co-planar to the main symmetry planes (e.g. NGC 2841, Sil'chenko et al. 1997, and NGC 7217, Sil'chenko & Afanasiev 2000) as well in many lenticular galaxies (Fig. ...
