Joining the Sisters

image by Peter Rosén, Stockholm, Sweden

Yesterday evening I took my bike to the eastern part of Stockholm and climbed to the top of a steep hill in the darkness to get to a vantage point, and arrived just in time for the moonrise. Behind the farthest lights lie the Baltic Sea (visible to the left), then Finland and Estonia on the other side. This year's Nobel Prize of Physics is awarded for the invention/discovery of the blue led light that together with the red and green is giving us strong white light at a much lower energy consumption and cost. For astronomers the other side of the coin is that we might get even more light pollution in the cities if we can afford to never turn the lights off in the future. In this view, the Moon and the Pleiades are still bright enough to shine through the thousands of lights from the city.
