Impressive and fascinating. I had no idea our galaxy was going to collide with another one!

Every major galaxy, it turns out, has a black hole at its core. Now, for the first time, scientists have the chance to study the havoc these mind-boggling entities wreak.</blockquote><div style="border-bottom: solid 1px #dcdcdc; white-space: nowrap; margin-bottom: 8px; background-color: #eeeeee ;background-image: url(http://clipmarks.com/images/source-bg.gif); background-repeat: repeat-x; height: 24px; line-height: 24px; vertical-align: middle; padding-bottom: 4px; color: #666666; font-size: 10px;" ><a href="http://clipmarks.com/clip-to-blog/" title="see clips that are hot right now"><img src="http://content9.clipmarks.com/images/clip-icon.gif" alt="" width="19" height="19" border="0" style="vertical-align: middle; margin: 0px 4px; display: inline; border: none; float:none;" /></a>clipped from <a title="http://www.smithsonianmag.com/science-nature/black-holes.html?c=y&page=4" href="http://www.smithsonianmag.com/science-nature/black-holes.html?c=y&page=4" style="font-size: 11px;">www.smithsonianmag.com</a></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.smithsonianmag.com/science-nature/black-holes.html?c=y&page=4">However, a fearsome collision looms. The closest large galaxy, called Andromeda, is on a collision course with the Milky Way. The two will start to merge about two billion years from now, gradually forming a massive galaxy that Loeb and his Harvard-Smithsonian colleague T. J. Cox call "Milkomeda."</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/8FFECC69-3546-4A61-99B9-F7FEDF9E218D/blog/" title="blog or email this clip"><img src="http://content6.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
