The whole clump of neighboring galaxies were being pulled off course at over one million miles per hour, towards something we couldn&#8217;t see.<\/p>\n<p>They called this region the Great Attractor. But their ability to study it was limited. <\/p>\n<p>&#8220;The Milky Way has millions and millions of stars and a lot of dust, which is blocking all that information that we could be measuring in that direction. So our own galaxy&#8217;s blocking the Great Attractor,&#8221; says Jorge Moreno, a computational astrophysicist at Pomona College.
