I saw an article the other day that was very interesting and a little shocking to me, it looks like it has been discovered that our Sun may have a Sister, and there could possibly be more of them also...wow!!!

All these new discoveries related to our Planet, other Planets, and the Solar System around us are just amazing. Almost every week we can read of a new discovery which almost boggles the mind, and makes us realize just what a small part of existence we really are. Also, it puts a new spin on whether or not there are or could be other worlds like ours out there somewhere.
