Now, look above it.&nbsp; Do you see something called the Shapley Concentration (yellow arrow)?&nbsp; It&rsquo;s behind the Great Attractor, and much further out.&nbsp; It&rsquo;s also what we&rsquo;re being drawn toward.<\/p><p>I hear gasps of dismay.&nbsp; In 2005, X-ray surveys in the &ldquo;Zone of Avoidance&rdquo; (the area behind the Milky Way which we normally can&rsquo;t study very well) confirmed that it was the Shapley Concentration we were being pulled toward, not the Great Attractor.&nbsp; In all fairness, it was the Great Attractor and its gravity anomaly which caused scientists to study the area so closely, only to rediscover this huge concentration behind it.<\/p><p><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/euvolution.com\/futurist-transhuman-news-blog\/wp-content\/plugins\/wp-o-matic\/cache\/50d29_Shapley.gif\" alt=\"File:Shapley.gif\" width=\"448\" height=\"336\" style=\"padding-left:10px;

Astronomers have long known the Milky Way is moving toward the constellation Centaurus, and at quite a respectable 1.4 million miles per hour.&nbsp; Many thought the pull was the Great Attractor, but with the use of X-rays to peer beyond the Milky Way&rsquo;s dust, they learned the Great Attractor didn&rsquo;t have nearly the matter they had originally thought.&nbsp; They also got a good look at the Shapley Concentration, and saw that it did have the matter.&nbsp; As a matter of fact, the Great Attractor is being pulled toward the Shapley Concentration.<\/p><p>Containing many thousands of times the mass of the Milky Way, and about 650 Mly away (that&rsquo;s million light years), the Shapley Concentration is a rare supermassive cluster of many galaxies.&nbsp; We are being drawn inexorably toward it, and will one day become a part of the cluster ourselves.<\/p><p>Oh, not &ldquo;us&rdquo; as in you and me&hellip; I mean &ldquo;us&rdquo; as in this galaxy.&nbsp; Humanity will be long gone by then, extinct on a planet no longer able to support life as we know it.&nbsp; In fact, we&rsquo;ll probably run into Andromeda long before we become a bug on the windshield of the Shapley Concentration.<\/p><p>So to speak.<\/p><p>Click <a href=\"http:\/\/tomsastroblog.com\/images\/tga010410.jpg\">here <\/a>to see a larger view of the first image.&nbsp;
