How dark is your sky? How far do you have to travel to reach a dark sky? Originally shared by Friends of NASA The New World Atlas of Artificial Sky Brightness How far are you from a naturally dark night sky? In increasing steps, this world map (medium | large) shows the effect of artificial night sky brightness on the visual appearance of the night sky. The brightness was modeled using high resolution satellite data and fit to thousands of night sky brightness measurements in recent work. Color-coded levels are compared to the natural sky brightness level for your location. For example, artificial sky brightness levels in yellow alter the natural appearance of the night sky. In red they hide the Milky Way in an artificial luminous fog. The results indicate that the historically common appearance of our galaxy at night is now lost for more than one-third of humanity. That includes 60% of Europeans and almost 80% of North Americans, along with inhabitants of other densely populated, ligh...

By way of Alicia Smith. For me, it is deeply moving - a look forward at looking back at an amazing first that is taking place right now . Originally shared by Friends of NASA Ambition: The Film [A Must See!] Ambition is a collaboration between Platige Image and the European Space Agency (ESA). Directed by Tomek Bagiński and starring Aiden Gillen and Aisling Franciosi, Ambition was shot on location in Iceland, and screened on October 24, 2014 during the British Film Institute’s celebration of "Sci-Fi: Days of Fear and Wonder", at the Southbank, London. Excellent work ESA and Platige Image!
