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 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. ...
