Rotating Galaxies

[jeremy_swinarton]

Our galaxy, the milky way, is slowly rotating. So if we can see objects that aren't part of our galaxy, why don't they appear to be rotating? Galaxies are listed on planispheres and star charts, so technically they shound stay in the same place. How fast does a galaxy rotate? Did I make a mistake somewhere?

Takes 200000000 to 250000000 years for galaxy to rotate once. Be patient, the view will change.<br /><br />Glad you're thinking about these things. <br /><br /><img src="/images/icons/smile.gif" /><br /><br /> <div class="Discussion_UserSignature"> <p><font color="#ff0000"><strong>TPTB went to Dallas and all I got was Plucked !!</strong></font></p><p><font color="#339966"><strong>So many people, so few recipes !!</strong></font></p><p><font color="#0000ff"><strong>Let's clean up this stinkhole !!</strong></font> </p> </div>

You might find this of some interest. Students for the Exploration and Development of Space (SEDS) http://www.seds.org/ They have a chapter in Canada at University of Waterloo (if that's close to you)<br /><br /><br />"SEDS is an independent, student-based organization which promotes the exploration and development of space. SEDS pursues this mission by educating people about the benefits of space, by supporting a network of interested students, by providing an opportunity for members to develop their leadership skills, and by inspiring people through involvement in space-related projects. SEDS believes in a space-faring civilization and that focusing the enthusiasm of young people is the key to our future in space." <div class="Discussion_UserSignature"> <font size="1" color="#3366ff">www.siriuslookers.org</font> </div>
