Exoplanets
      Alley has been learning about our solar systems planets in school.  She loves it!  She finds videos on line to learn more - did you know Saturn has Shepard moons to keep the rings together?  And she has a theory about dark matter.  Last night we went to the U of M to their public lectures on space.  It was about exoplanets - planets in other solar systems that have been discovered. We then went up on the roof to look at Jupiter and 4 of its moons. I asked the grad student giving the lecture why bettlejeuse star in the constellation Orion was red - he started to answer then Alley finished saying - it is a very old star that has become a red giant and means it will go supernova eventually.  I guess I should have asked my 9 year old.
