The New Scientist reports that the gravitational pull of another galaxy, hidden inside our own, could explain the mystery.

Other scientists disagree. Instead, dissenters argue that a supercluster of galaxies, 700 million light years away and many times larger than the Milky Way, is the more likely culprit. —Sarah Pumroy

For a snapshot into our galaxy and beyond, read Anthony Doerr’s “Worlds Without End” from the September/October issue of Utne Reader.

Correction: The hidden galaxy is thought to be in the space behind the Milky Way, not inside it as originally reported.

"hidden inside our own Milky Way" is a gross misinterpretation of the article, and makes absolutely no sense, taken on its own.
