Nothing to see here, just a galaxy or three... hundred:

Hundreds of hidden nearby galaxies have been studied for the first time, shedding light on a mysterious gravitational anomaly dubbed the Great Attractor. Despite being just 250 million light-years from Earth — very close in astronomical terms — the new galaxies had been hidden from view until now by our Milky Way Galaxy.

Using CSIRO's Parkes radio telescope equipped with an innovative receiver, an international team of scientists was able to see through the stars and dust of the Milky Way into a previously unexplored region of space. The discovery may help to explain the Great Attractor region, which appears to be drawing the Milky Way and hundreds of thousands of other galaxies towards it with a gravitational force equivalent to a million billion Suns.

Lister Staveley-Smith, from The University of Western Australia node of the International Center for Radio Astronomy Research, said the team found 883 galaxies, a third of which had never been seen before. "The Milky Way is very beautiful of course, and it's very interesting to study our own galaxy, but it completely blocks out the view of the more distant galaxies behind it," he said.

Statement at the International Centre for Radio Astronomy Research, and another article at Space.com.
