Over 800 Galaxies Found Hiding Behind The Milky Way

Astronomers in Australia have found 883 new surrounding galaxies, one third of which were not known to exist until now.  This discovery was made possible by their new method of observing stars, which uses a radio telescope to see through the Milky Way, our home galaxy.  Prior to the use of the radio telescope, these distant galaxies had been hidden by the dust and surrounding stars of the Milky Way, which made them impossible to be seen using conventional telescopes.  According to the study published in the Astronomical Journal on Tuesday, the galaxies are 250 million light years from Earth.

This discovery could help researchers understand the “Great Attractor,” a region of space that is drawing the Milky Way and other galaxies toward it at speeds more than 1.2 million mph.  Currently, it’s not understood why this strange gravitational force is happening, or where it’s coming from.

This is just another reminder of how much “unknown” there is out there, even within our own cosmic neighborhood.  Leave a comment if you have any questions.
