It's the question that everyone wants answered. And now, with the most powerful telescope of it's kind in the world, Australian astronomers may be about to find out in their search for hidden galaxies. Even with a radio telescope as powerful as the one at Parkes, astronomers can take a long time to search the skies. Any galaxies beyond our own are faint and give out little light. Some are hidden by the stars and the dust of the Milky Way. Astronomers find hidden galaxies by looking for radio waves that come from cool hydrogene gas, the stuff that stars are made from. But the problem in the past has been that the radio waves are so weak that it takes a long time to find them.
