We still really don't know for sure how many arms there are. <BR/><BR/>Since we are right in the middle of things we are not looking at our galaxy from a proper perspective, we can't see the forest for the trees so to speak. Plus the fact that we have so much cosmic dust in the way it is really hard to tell for sure the amount of arms we have.<BR/><BR/>With the use of new technology, like in the book I described in my post we are seeing more clearly, I remember reading the link you cited,excellent link BTW, I love the phrase.<BR/>"Here there be dragons",lol.<BR/><BR/>Masers have really a simple job that is to provide an extremely accurate frequency that we can among other things base time on for example.<BR/><BR/>Awesome post!!Bob Johnsonhttp://www.blogger.com/profile/06582050569176409358noreply@blogger.comtag:blogger.com,1999:blog-7371096836760304449.post-82797907012942664842009-01-09T15:43:00.000-08:002009-01-09T15:43:00.000-08:00I like astronomy too.<BR/>There's a neat site which has the "Astronomy Picture Of The Day".<BR/>You probably already know all about it. :)<BR/><BR/>http://antwrp.gsfc.nasa.gov/apod/astropix.htmlJannahttp://www.blogger.com/profile/04827716404911856909noreply@blogger.comtag:blogger.com,1999:blog-7371096836760304449.post-84898242941702701252009-01-08T12:00:00.000-08:002009-01-08T12:00:00.000-08:00I love astronomy. Even though I'm not pursuing a career in this field, I'm still fascinated by it. There's so much to explore and it looks beautiful.<BR/><BR/>http://dratiffarid.today.comdratiffaridhttp://www.blogger.com/profile/00855903995028334809noreply@blogger.com
