1. Probably a Planet for Beta Pic
Astronomy Picture of the Day . Probably a Planet for Beta Pic . ... 28.11.2008 . ... Explanation: A mere 50 light-years away, young star Beta Pictoris became one of the most important stars in the sky in the early 1980s. Satellite and ground-based telescopic observations revealed the presence of a surrounding outer, dusty, debris disk and an inner clear zone about the size of our solar system -- strong evidence for the formation of planets . ... November 2008 . ... 2007 2008 . ...

2. Hubble Finds Oxygen Atmosphere On Jupiter's Moon Europa
Hubble Finds Oxygen Atmosphere On Jupiter's Moon Europa . Astronomers using NASA's Hubble Space Telescope (HST) have identified the presence of an extremely tenuous atmosphere of molecular oxygen around Jupiter's second moon, Europa . ... Europa's oxygen atmosphere is so tenuous that its surface pressure is barely one hundred billionth that of the Earth," said Principal Investigator Doyle Hall, of Johns Hopkins. ... The oxygen gas slowly leaks into space and must be replenished continuously. ...

6. Armagh Observatory
... Armagh Observatory, College Hill, Armagh BT61 9DG, +44 (0)28 3752 2928 . ... The stars of the middle main sequence have relatively quiescent outer layers, and unusual chemical abundance patterns may develop in their atmospheres. ... At present, little is known about the time evolution of these anomalous abundances, nor about the role that diffusion may play in maintaining them, during the main sequence lifetime of such a star. ...

7. Why do people want to explore Mars
Why do people want to explore Mars? At the present time Mars topography is known sufficiently well to make a Martian map; we cannot distinguish yet the settlements of the inhabitants of this planet, but sooner or later we probably will be able to achieve this as well.. ... US spacecraft "Mariner-4" performed the first successful flyby and transmitted to the Earth twenty one photos of Mars' surface. ... It is supposed that large subsurface ice reservoirs or liquid water exist on Mars. ...

8. Basics of Wind Energy
velocity measured in meters per second . ... High speed propeller (vertical) = 42% Clearly, wind power is a highly variable source and hence energy storage is crucial. ... Electricity generated is then .25 KWH per sq. meter . If wind blows 24 hours per day then annual electricity generated would be about 2200 KWH per sq. meter . ... To Generate 10,000 KWH annual then from a 20 mph wind that blows 10% of the time . windmill area = 10,000 KWH/220 KHW per sq. meter = 45 sq meters . ...

9. Chemical depletion in the Large Magellanic Cloud: RV Tauri stars and the
... By studying the photospheric abundances of 4 RV Tauri stars in the LMC, we test whether the depletion pattern of refractory elements, seen in similar Galactic sources, is also common for extragalactic sources. Since this depletion process probably only occurs through interaction with a stable disc, we investigate the circumstellar environment of these sources. ... One source shows a very small infrared excess, atypical for a disc source, but still has evidence for depletion. ...

10. New data on the cpmplex field structure of chemically peculiar stars
... As a result of BTA observations of 23 chemically peculiar stars with strong magnetic fields, it was found that in 22 of them the longitudinal magnetic field, measured from the hydrogen line cores are considerably lower (by about 1/3) than the value measured from metal lines in the same spectra. ... New approaches need to be developed in order to interpret the data. ... The Zeeman spectrum of a star with a strong magnetic field, 53 Cam. ...
