This x-ray map is much more than a beautiful desktop background. By Allison Kubo On June 19, the eRosita instrument aboard the Russian-German “Spectrum-Roentgen-Gamma” (SRG) mission finished cataloging more that 1 million high energy x-ray sources more than had ever been recorded before this study. The image above shows our sky illuminated in x-rays, the

What Planck saw: does the cosmic microwave background harbour evidence for loop quantum cosmology? (Courtesy: ESA and the Planck Collaboration) A theory of quantum gravity that describes the universe as beginning in a “Big Bounce” rather than a Big Bang has succeeded in explaining several anomalies in the cosmic microwave background (CMB) radiation. Loop quantum
