Light Echoes Reveal Exploded Stars - Space.com  The explosions occurred centuries ago, the astronomers said, with the oldest having erupted about 600 years ago in Earth-time. All three occurred in the Large Magellanic Cloud (LMC), a satellite galaxy to our Milky Way. The LMC is about 160,000 light-years away. In images taken years apart, researchers found concentric, circular-shaped arcs best explained as light moving outward over time and being scattered as it encounters dense pockets of interstellar dust    
ZeroG Launches Space Tourism For The Masses - Seattle Times  Starting at $49, anyone can enter the space frontier by sending a small item into orbit. Items suggested include business cards, small boxes filled with keepsakes, or even ashes. Following each trip, items are returned with detailed flight information and an official ZeroG Certified Space Seal to authenticate their space travel. In addition, people who send items into space will become a part of history as names are entered in the International Space Registry. ZGS-1 will blast into space at 4,000 MPH on a high performance sub-orbital rocket developed by UP Aerospace, Inc.    

Galaxy's Neighboring Spiral Arm Is Closer Than Thought - SpaceDaily  The Perseus spiral arm - the nearest spiral arm in the Milky Way outside the Sun's orbit - lies only half as far from Earth as some previous studies had suggested. An international team of astronomers measured a highly accurate distance to the Perseus arm for the first time using a globe-spanning system of radio dishes known as the Very Long Baseline Array (VLBA), which offers the sharpest vision of any telescope  in existence. Additional VLBA measurements will help astronomers to determine the true structure of the Milky Way. The Perseus spiral arm is located about 6,400 light-years from the Earth.
