When galaxies collide: How the first super-massive black holes were born - August 26 Astronomers believe they have discovered the origin of our universe's first super-massive black holes, which formed some 13 billion years ago. The discovery fills in a missing chapter of our universe's early history, and could help write the next chapter -- in which scientists better understand how gravity and dark matter formed the universe as we know it....Read More
Solar System may be 2 million years older than we thought, meteorite analysis suggests - August 25 Timescales of early Solar System processes rely on precise, accurate and consistent ages obtained with radiometric dating. However, recent advances in instrumentation now allow scientists to make more precise measurements, some of which are revealing inconsistencies in the ages of samples. Seeking better constraints on the age of the Solar System, researchers analyzed meteorite Northwest Africa (NWA) 2364 and found that the age of the Solar System predates previous estimates by up to 1.9...Read More

NASA's Kepler spacecraft has discovered the first confirmed planetary system with more than one planet crossing in front of, or transiting, the same star.
Strange case of solar flares and radioactive elements - August 25 When researchers found an unusual linkage between solar flares and the inner life of radioactive elements on Earth, it touched off a scientific detective investigation that could end up protecting the lives of space-walking astronauts and maybe even rewriting some of the assumptions of physics....Read More
