Is the matter in the universe arranged in a fractal pattern? A new study of nearly a million galaxies suggests it is though there are no well-accepted theories to explain why that would be so. Cosmologists trying to reconstruct the entire history of the universe have precious few clues from which to w...

Galaxies are not as isolated as they at first glance may seem; on a cosmic scale they congregate in clumps along with dark matter and hot gas. The colourful blob in this new composite image, based on data from several telescopes including ESA's XMM-Newton, is the group of galaxies known as the Bullet G...
