Water Discovered in Moon Shadow . ... Credit Copyright: LCROSS , NASA Explanation: Why is there water on the Moon? Last month, the LCROSS mission crashed a large impactor into a permanently shadowed crater near the Moon's South Pole. A plume of dust rose that was visible to the satellite , although hard to discern from Earth. The plume is shown above in visible light. Last week, the results of a preliminary chemical analysis gave a clear indication that the dust plume contained water . ...

XMM-Newton Science Analysis System . ... Meta Index / Home Page / Description / Exposure corrections in detail: . A proportion of detected events are `minimum ionising particles' (MIPs). During each ccd frame, pixels occupied by a MIP are not free to detect an xray; hence MIPs lead to xray flux loss. The fraction of affected pixels is stored in the FRACEXP column of the EXPOSUnn extensions (the `nn' indicating the ccd/node) of the event list. ... XMM-Newton SOC/SSC -- 2006-06-28 ...

We present the analysis of supernova remnants (SNRs) in the Large Magellanic Cloud (LMC) and their influence on the environment at far-infrared (FIR) and submillimeter wavelengths. ... Most of the dust that is seen is pre-existing interstellar dust in which SNRs leave imprints. ...

... The degree of correlation between two parameters can visually be estimated by plotting them. Numerically this is expressed by the correlation coefficient : . ... When the correlation coefficient indicates a significant correlation, the functional relation is given by the regression line which is computed by least squares methods for normal distributions or maximum likelihood procedures (see Section ). ... Such transformation may also be used to make the variance of a variable homogenous. ...

... We present an analysis of an optical blue spectrum of the pulsating helium star V652 Her (=BD+13 3224$) in order to determine its effective temperature, surface gravity and chemical composition. ... The surface composition is characterised by abundances of nH=0.009, He=0.988, nC~0.000040, nN=0.0025 and nO=0.00010 (number fractions). ... If V652 Her was formed by the merger of two white dwarfs, its surface composition demands that they should both be helium white dwarfs. ...

... The effect of the bug has been that timestamps indicating when data was taken (FITS-header keyword CRVAL5) may be off by one second. ... DETAILED DESCRIPTION -------------------- AFFECTED KEYWORD: The affected keyword is: CRVAL5 (time stamp indicating start time of subscan) Synchronisation errors between the 1PPS pulses and the NTP-controlled system clocks have frequently caused the timestamps indicating the start of each subscan (CRVAL5) to be off by one second. ... That problem has also been fixed...

... The improvement will be more pronounced in our crowded Wide Field Camera (WFC) images, and may be increased further through use of a more sophisticated method of combining the individual dithered images. Our analysis allows us to check for point spread function shape variations in the HST Planetary Camera (PC) field. ... In crowded field images, we are deriving information about the faint end of the luminosity function (LF) from the texture of the image background. ...

... A correlation between metal abundance and orbital elements (the eccentricity and angular momentum) has been found for three semples of disk stars of our Galaxy with abundance derived from detailed analysis. The correlation indicates that metal abundance in the Galaxy kept increasing after the birth of old disk stars and that the Galaxy kept collapsing during the formation of its disk subsystems. ...
