Typical night sky brightness at two locations: the top plot is Kitt Peak in Arizona, the bottom is near the center of Berlin. NSU is how bright it is compared to a starry sky.
Distribution of news on the New York times. One of the databases used for this research. Dates correspond to the position of the sun on 2013.
· Analysis of the appearance frequency of these superbolides and big fireballs (meteors brighter than the Full Moon) shows how some dates have a greater abundance, as it does with meteor showers (much smaller meteoroids). This is direct evidence on the existence of small asteroids yet to be discovered, that cross Earth’s orbit and may impact it.
· Researchers and students of Universidad Complutense de Madrid started a citizen science project delving into national and international newspapers archives like New York Times and El País.
· The preliminary results were presented in the XXI National Astronomy Conference hold in Granada, Spain in May 2014 (http://goo.gl/Ngwshw).
Among the research on light pollution by the GUAIX group, we have recently launch the website www.citiesatnight.org which holds the first atlas of night time ISS images. This is a citizen science project leaded by UCM people.
