Rosetta s continued close study of Comet 67P/Churyumov€н Gerasimenko has revealed an unexpected process at work close to the comet nucleus that causes the rapid breakup of water and carbon dioxide molecules. First, an ultraviolet photon from the Sun hits a water molecule in the comet s coma and ionizes it, knocking out an energetic electron. This electron then hits another water molecule in the coma, breaking it apart into two hydrogen atoms and one oxygen, and energizing them in the process. ...

If the Universe is flat, it is forever balanced between open and closed; it will expand forever, but always slowing, just balancing gravity. ... Basically, if the Universe is open (will expand forever), closed (will eventually contract again) or flat (expanding just fast enough to balance gravity), you will see differences in the way the SN behave. ...

... On rare occasions (few times a year or so), ground based observations in the morning sector show highly monochromatic amplitude modulated oscillations in the Pc 4 range (see the sample ). ... As these particles circle the Earth and reach the morning hours only when the ExB drift is small, giant pulsations are observed only during geomagnetically quiet times (Chisham, 1996). ...
