Direct link International Dark Sky Parks and Reserves - Just in Time for Summer Vacation!

16 Jun 2009, 00:21 UTC International Dark-Sky Association The world’s national parks and open spaces are a haven for summer tourists interested in hiking, camping, biking, bird watching and a slew of other outdoor activities. Why not add one to the list – stargazing? Many tourists stumble upon the beauty of the natural night sky while at these destinations. Well we’d like to emphasize making them a planned part of your summer vacation; and if you’re headed to the parks, make sure to look up at night, it’s guaranteed to be a celestial site. In addition, learn about collaborative efforts designed to protect these areas from onsite and encroaching light pollution. www.darksky.org Established in 1988, the International Dark-Sky Association is an educational, environmental 501(c)(3) nonprofit dedicated to protecting and preserving the nighttime environment and our heritage of dark skies through quality outdoor lighting.

Direct link Does Dark Matter Really Exist?

Observations of the rotational curves of galaxies and certain properties of the cosmic microwave background can not be explained with current theories unless the universe contains many times the mass that composes the stars and gas that we can observe directly. While the search for dark matter goes on, some scientists are not convinced it exists and have proposed an alternative explanation knows as Modified Gravity Theory or MOG. They believe that Einstein’s theory of gravity is incomplete and that a new gravitational theory can explain these anomalous observations.
