The First Law (1): Energy is Conserved in a closed system: . ... We usually consider work and heat flow as the two kinds of energy . The Second Law (2): The Law of Entropy: . ... The amount of disorder increases . ... You can not go from a disordered system to an ordered system without inputting more energy (this is the most important attribute of the second law) . ... In no way can we recover work of that this disordered system without putting energy into the system. ... More on Thermodynamics . ...

Molecular clouds in the central 200 pc of the Galaxy (the Central Molecular Zone ) exhibit different (and more extreme) physical properties than those in the disk, yet because this is the closest galactic nucleus, detailed studies of this region can provide insight on galactic nuclei in general in the nearby universe. ... In this talk I will present a case study of one of the clouds - a dense and unusual cloud, GCM0.253+0.016 - also known as The Brick . ...

... Compressional Pc 5 ( ULF ) waves, found on the nightside close to the flanks of the magnetosphere , are the dominant pulsations occurring beyond L =8. ... Accordingly, the events are strongly associated with high beta plasma clouds and are much more likely to be observed near the equator than >10њ off the equator (see, e.g., Anderson, 1993). ... Azimuthally polarized toroidal Pc 5 pulsations are thought to be fundamental mode toroidal field line resonances (FLR) with magnetic node at the equator. ...

I was wondering what conditions should be met to have the "darkest" sky .. ... Upon the above publication of the Southern Galactic hemisphere, TunГ Tezel started seeking opportunities to create the Northern counterpart image. ... So, the initial quest of having the darkest possible sky have delivered us these two all-sky images of the two galactic hemispheres as seen from Planet Earth. Zoomable and 'full-screenable' fisheye view of the "darkest sky" Southern Galactic Hemisphere image. ...

The Very Large Telescope Interferometer (VLTI) at ESO s Paranal Observatory in Chile has obtained the sharpest view ever of the dusty disk around the close pair of aging stars IRAS 08544-4431. For the first time, such disks can be compared to the disks around young stars and they look surprisingly similar. ... The inset shows the VLTI reconstructed image, with the brighter central star removed. The background view shows the surroundings of this star in the constellation Vela the Sails. ...

... The frequency and properties of young tidal dwarf galaxies in nearby gas-rich groups . ... Gaseous material pulled from initial close encounters between galaxies can produce second-generation tidal dwarf galaxies (TDGs), which differ from first-generation `classical' dwarfs by their higher metal content and lack of dark matter. I present the results of a multi-wavelength investigation of the dwarf galaxy populations in three gas-rich interacting galaxy groups: NGC 871/7, NGC 3166/9, NGC 4725/47. ...

... Predictions for Leonids 2009 . 55P/Tempel-Tuttle , the parent comet of the Leonid stream, returns to perihelion every 33 years or so (in fact very close to 3 times a century), generating a new trail of meteoroids and dust each time. ... A review article by David Asher entitled `Leonid dust trail theories' is available as paper number 346 in the Armagh preprint/reprint series . ... McNaught and Asher have developed a model to estimate Zenithal Hourly Rates of meteors during trail encounters. ...
