I have a question for all you astronomy lovers... i've been studying our
Local Group of galaxies and find nothing about the shift, red or blue, of the Triangulum Galaxy (M33 and NGC 598). Of the forty or so galaxies in our LG, there are only three that are very large. The largest, Andromeda Galaxy shows a blue shift, which means that its motion is in our general direction (some sources say that this galaxy is heading directly toward us, but i don't see how they can deduce this simply from a blue shift). Our very own Milky Way Galaxy has been measured to be moving away from the Virgo Cluster, a large cluster of galaxies in the constellation Virgo, a prominent Springtime star group (U.S.A.). The Triangulum Galaxy has been found to be moving *toward* the Virgo Cluster. Since the Triangulum and Andromeda constellations are most prominent during Autumn, can we deduce the following? 1) The Andromeda Galaxy is also moving toward the Virgo Cluster, and 2) The Triangulum Galaxy, like Andromeda, also shows a blue shift. I haven't been able to find the answers to these specific points in any of my sources. You come highly recommended! happy days and... starry starry nights! -- Life without love is A lamp without oil, Love without prejudice A world without soil, Tool without toil. Paine Ellsworth |
