Amateur Space News May 14, 2014

Crowdsourced reports of light pollution lead today’s headlines. Also follow-up reports on the Team America Rocketry Challenge and Mars One.

Amateur observations of the night sky document light pollution. The citizen science project Globe at Night asks people around the world to observe specific constellations and report the faintest stars they can see. American astronomers at the National Optical Astronomical Observatory and Morehead State University analyzed seven years of Globe at Night data for a paper accepted into the peer-reviewed Journal of the American Association of Variable Star Observers. The paper cites a report that 20% of the world can’t see the Milky Way due to light pollution - a share of the population that rises to 50% in the European Union and 66% in the United States. Their analysis shows that light pollution levels reported by Globe at Night has remained constant despite rising urbanization. You can read the PDF preprint.
